Hi riolow,

FrownFrownFrownFrown..... Green water is coming to my pond again...!!!!!
I install the uv light again, so i think the green water wont bloom.
But i hav to find out why????? would tat b the tap water??
Last time the algae bloom like this also.


Hi Chris,

How's your pond water now? Is the green water under control? Mine is still crystal clear and hope it stays that way. BTW, my UV is still running at 24x7.

Hi Epal63,

My pond water get back to cloudy, Installed the uv light on Monday until now still cloudy.FrownFrownFrownFrownFrownFrownFrown
I think may b the bacteria collapse again cause by the chlorinate tap water.
Have to wait few days or may b some more weeks and see whether the bacteria will grow back or not.
Will update photos on monday....

1. I WC once in every two wks... but I hav dropping water to the C1 every day...
2. If I'm washing the filter in every two wks... It's abt 10 % of my pond... for the dropping water, cant really estimate the % per day... bt it's abt 2% +/- korTongueTongueTongue
3. I wash my brush every two wks... J.mat & bio media, hmmmm, abt 6 mnths... but sure wth pond water ler... (P/S: I do 'sharking' the J.mat when I discharge the filter water...
4. abt 21 tons (see attached excel file)SmileSmile
5. tis I cant really answer U, as I dont know at the pump I used. As my dad ask some1 built it... n I was not know wat is Koi at tat time... n so I dont have dry champer & deep 'charfer' at my filterPiratePiratePirate... Anyway, I have two pipe tat water pump the water to the filter... 1 is abt 1&half" n other is 3"... no sure wil measure next time...

I hav add n change media... as compared to original 1TongueTongueTongue

How is PS? is it work? N water ok now?

Re: [riolow] Diy Protein Skimmer... [In reply to] Can't Post

Chris, i read most of your post and felt very sorry for having to go through it...

just some input though merely a one year old hobbyist but had quite a few years in marine/ reef until i got my first daugther then gave up as high maintenance. though many will not agree to what i'm going to say but just some thoughts.

Honestly, after reading many post for the past months and also experiencing treating diseases, i notice many hobbyist including myself at the beginning are just too cautious and too diligent. What i meant is that, we often change the water too much, clean the sediments, wash the brushes/ matt etc every 2 weeks or 1 month with some at the extreme of weekly.

Honestly, i dont think its necessary at all. The best once a month, we flush out the sediments and dry up the filter chambers and refill with pond water then top up. Touch wood, after a year into this, so far my pond has been clear and readings are good except the few incidence of diseases at the beginning as i didnt quarantine the koi as i just dump them into the pond. Since then, i have stop doing and do quarantine at least 2 to 4 weeks.

I have seen many including my relative pond where they only do the cleaning once in 2 or 3 months and they never had any problems with the water or koi.

Often, problems with water and koi are really self inflated as we change the water too often, not knowingly flushing or cleaning or killing the good bacteria instead of otherwise.

Anyway, in short, in your case, suggest u keep whatever system you have as is for a while. What u really need is at least a 40 w UV light and place it in your last chamber where the pump is and wait for a week or 2. I'm quite sure it will work. Pls dont turn off when the water is clear but keep it on 24/7 and as long as it can last and replace if otherwise. the other thing is your O2, noted u mention about 40 w air pump, not sure what type is it? is it those for aquarium? what u need is something like Hiblow preferably 80 where its much powerful and will reallly oxigenate your pond and bio filter. U can get the cheaper ones made in china which i used to buy but went capput in less than 3 months, then decided once and for all get something which is more reliable since the cost is really nothing much if u compare to the cost of koi that all of us buy. Remember, based on your pond size, place at least 2 airstone (get those flat and round about 6 inch or larger in diameter) in your pond. For filter, just buy the cheap airstone and place a few in each chamber. Suggest just place mid way down and not right at the bottom as it will stir up the sediments.

All in all, try the above and see how it goes as it cost lesser and less energy to reconstruct your filters etc. Personally, for me, koi keeping is a hobby and its something that we enjoy but it cant be a burden to u where u have to spend hours a week cleaning filters etc though we can outsource but again, why? Koi suppose to be hardy fishes even hardier than gold fish or tropical fish. As mention, i kept a 7 feet reef aquarium in the past and i only really need to spend an hour a week to top up the water plus adding nutrients. We cant be spending the same for koi which are suppose to be maintenance less/ free.

Some reservation, as i have said, am only a year into this hence i may be wrong and i dont intend to offend anyone in this forum especially the sifus....just my personal thoughts....

Good luck

Re: [vince68] Diy Protein Skimmer... [In reply to] Can't Post

hi vince..

i agree with u when u said cleaning filter or chamber too frequent is not good. well, it depends on how much ur feeding and ur koi stock inside pond as well.. and i wud suggest to others is to have less stock of koi, then less feeding can b apply thus less waste in chamber..

as for UV light, my suggestion will b in the settlement chamber.. the most dirty water is here, if u put the UV at the last chamber very high % of good bacteria will b killed.. at least if put in the SC the good bacteria from the bip chamber can flow back into pond.. just a suggestion.. any comment are welcome..

Hi vince,

Wow!!! thanks to read all my story...
And ya, u r right... i m too cautious to my pond. I always said the same thing to my friends,
but i m the one doing the worst thing....
Some of my friends also hav koi pond, but their pond is clean and clear.
Not need wash brush or drain water, just adding water once a week or month.
As wat u said, their pond dont hav algae problem....

For now i will keep yr advise and try to get a higher W of uv light to treat the algae problem. Then the next will b more easy to do. Just drain the SC once a week and wash brush once 2-4weeks.... CoolCoolCoolCoolCoolCool..........
Wow... now i feel like throw away a hundred kilo of stuff on my shoulder. kekekeke......

I m using a 40w Hi-blow air pump with 12pcs of air line to the bio chambers only. Do u think i need to take 1 or 2 air line to place into the pond? or just get a new one instead?
I hav water turn back to the pond from T.T, Do u think tat enough O2 for the pond?

Anyway thank u for your advise and very very much appreciated.......SmileSmileSmileSmileSmile

Hi chris..

if u r in KL, visit kepongkoi and see his set up, not the best but personally i think can work..

water coming into a pump /settlement chamber then to another chamber containing UV light shine on to a thin layer of water b4 going through submerged BH then over flow back to a bakki shower, again with bacteria hse inside..
the whole idea is to kill off bacteria from bottom drain (which, theoritically have more bad than good bacteria) thus reduce the 'work' of good bacteria in the bio filter chamber...

in ur case, ur UV light is those built-in with pump type, the type i m talking abt is a germicidal lamp, 2ft in length, look alike those house-hold light bulb.. dont hv the picture at the moment, will post onces got the picture just to share with u..

Re: [chriswu3311] Diy Protein Skimmer... [In reply to] Can't Post

No problem as its a pleasure to read all those views and comments, as we all know, we learn from mistakes.

On the airline, you should have at least 1 or 2 in your main pond at your far corner and if u have diff depth, then the deepest otherwise the corners will do fine. 40w Hiblow should do fine if u have the rest midway in the filter chambers otherwise, may not be strong enough. Though there will be suff O2 from TT but my issue is really how regulated is your pond? ie is there enough current to move the water around? IN short, it would be good if u can have a water pump pushing water either near the surface or mid way level at the other end of the pond where the skimmer, so that the water can move from the inlet to the pond and be pushed in a circular motion into the other end of the pond into the filter. Just like a U shape motion. This is to enable the O2 to be distributed well.
FYI, my pond is also not covered and its open but i dont have any green water problem since day 1. Hence, i honestly think there isnt anything wrong with your set up except those i mention and i still believe UV will do the trick.

We need to enjoy the hobby but not get overly intense into it and instead of spending time wtih your family, u ended up with the fish and family neglected. Thats what really happen at the beginning but now, its otehrwise and everything seems to be fine.

Re: [koi@kit] Diy Protein Skimmer... [In reply to] Can't Post

Chris/ koi kit, i dont think its really significantly diff if its in the last or 1st chamber. The reason for my proposal is first due to my personal experience at the last chamber. Honestly, either chamber would have possibly kill good bacteria but its a matter of how we can minimize it and eliminate what we really want to. Hence, theoreticaly, last chamber would be ideal since whatever good bacter would have stayed in the bio chambers hence minimizing the impact as compared to the first where the main pond being 70% of the entire set up would have plenty of good bacteria within the pond, and if we place the UV in the 1st chamber, we basically wipe off all good bacteria from getting into the bio chambers.
Anyway, am not a scientist nor chemist but just some thoughts.

Re: [chriswu3311] Diy Protein Skimmer... [In reply to] Can't Post

Sorry, didnt see your post with regards to the water flowing into the TT.

I'm not sure if u remember, my set up is almost similar, where my UV is placed in the last chamber and the water will flow both direct to the pond and the other to the water fall (supposedly TT).

As what Koi Kit said, u should have brushes in your last chamber as those brushes are to trap waste. Your last chamber by right in theory should be clean from waste or sediments.

About using the old 5W UV, pls dont waste time as it will never work, just get yourself a 40 W above and place vertically in your last chamber, i dont think it cost u much at all. Then let us know what happen.

Good luck

Thank u so much....WinkWinkWink

Ok back to our topic...
I place the air stone at the midway of the filter chamber (about 8-10" from bottom).
I hav 3 sub. pump for my pond - 1st & 3rd outlet r pass to the 2 different t.t then back to the pond (pond surface)
2nd is pump to 2 outlet which at the midway of my pond and both facing down to the pond bottom.
I hav an idea, wat if i buy a O2 test kit to test the water DO? so tat i can know the actual DO in my pond.
Actually i tried to find it for so long, but still cant buy any.

I hope u didnt tell her the actual cost of each fish!!! i never and always throw away the receipt when i buy and always do it when home minister is away...ha ha... FYI, just got a couple last night (HM is late for home) and just spent RM3K.

Anyway, back to O2, from what i read, i dont think u should waste money in the tester as its not at all accurate and often reading change drastically. With 40 W Hiblow, 3 pumps and based on your pond size, its more than sufficient, doubt the test kit will do much help.

Just go and buy the 40w UV light and test it for a week or two and see how it goes....

I agree with this reasoning as I also have my UV in the last chamber.

Further, the purpose of UV is to get rid of Algea (green water). So, by having the UV in the last chamber, it reduces the "live" algea from being flow back into your main pond. Anyway, that's my thinking only.

Re: [vince68] Diy Protein Skimmer... [In reply to] Can't Post

hi vince..

i think u r rite abt UV placement weither in 1st or last chamber.. coz ur reason is good bacteria will stay 70% in the pond..

i personally think 1st chamber will b the more 'dirty' water ie.. lots of waste thus chances of bad bacteria is higher, dont u think so?.. as for last chamber after the water was purified by the bio chamber the chances of good bacteria is higher, logic? correct me if i m wrong..SlyLaugh..

btw i didnt say brushes in the last chamber, did i??Crazy.. i just said settlement chamber shud b empty, then 1st chamber with brushes, reason is to et the heavier waste to settle in SC soo easier for us to clean, 1st chamber fill with brushes will filter out other escaped waste soo the bio chamber wont clog with waste, as this will give more burden to the good bacteria.. remember good bacteria need oxygen, if cover with waste they will bcome anaerobic, sort of bad bacteria..
just my opinion...Sly

Hi guys,
Just bought 1 x 20w uv light (2ft) this morning. I did not buy 40w bulb bcos tat is 4ft long,
not suitable for my filter chamber.
The uv tube cost rm45 + 13.00 E.ballast with holder = rm58.00 is tat cheap??
1st I will DIY a casing (bcos no casing include) then install it to my pond for 1-2 weeks,
if still not strong enough i will buy another 20w install together in the same casing.

Re: [koi@kit] Diy Protein Skimmer... [In reply to] Can't Post

Hi Koi Kit, honestly if u ask me, there is really no right or wrong as different people has differnt views but as long as u dont face any problems with your pond based on whatever set up u have, u should leave it alone and dont do anything to change for the sake of it. Reason being there is just too many factors causing problems and no one is expert to resolve that. SOme may say is the filter, others may say is the the set up and at the extreme the material your contractor used in building the pond!!!

On the brushes, am referring to CHris comments not yours as u did correct him which i did.

Back to your placement of UV, u have a point but we are not chemist to understand how it really works. To me, there are good and bad bacteria all over but our task is really to minimise bad bacteria but keep as much good bacteria. Hence, placing in the first bacteria will basically kill everything before it goes to bio filter hence chance of good bacteria growing or multiplying is much lower as we have already killed them before they can reside in the bio filter. Noted, those which are already there will continue to multiply but not to the extend that its intended, i suppose.

Placing in the last chamber would be more ideal in that sense. Again, whether bad bacteria will also stay with the good at the bio filter is a question that i have no answer to but presumed only good will reside in bio whilst the bad will want to get out hence into the last chamber where we will kill them with UV. Another question which i have no answer but assumed is UV will kill bad bacteria but what is really bad bacteria? I know for sure UV will kill algae but not sure about bacteria though.

Anyway, as i have said, there is no right or wrong but as long as it works well for you, dont change for the sake of it as it will give more harm than good.

In the case of Chris, nothing is working, hence some some input and hope his will turn out well and stay well for a long time so that he dont have to waste too much time and energy....

Chris, casing? why dont u get from the fish shop where its water proof and i think it cost about the same or a little more and that will include everything, no separage ballast or casing.

DIY electrical stuff is a risky thing as the UV is suppose to be submerged and if there is a crack in your casing, your pond will be electrocuted and you koi may have spasm and if u touch the water, u will also get the shock!! i had it before hence dont risk it....not worth the money...bro

This morning i went to the largest light shop in my place and i ask for 20w or 40w uv tube. Then staffs dont even know wat is uv lights....hahahaha...
They though tat is for trapping fly tube (tat one also purple colour)....
After asking to the Boss and got 1 for me and the boss told me tat only hospital will buy those uv light from him....
