water condition	Can't Post

Hello to everyone

Me and my wife have been reading this forum for a while and it is from reading this site that we come to understand the importance of water condition for a koi pond.
We started by using our planter box and two weeks later we dug a 8ft x 8ft x 2 ft pond using pond liner with 22 small koi we brought. Two friends came to our house and each gave 20 mid size koi and we end up with 62 kois. After 2 months we extended the ponds to 22 ft x 8 ft x 3 ft . we had a lot of problem with the water ( green ) which we solved by using uv. we did not know about Ph,Kh,ammonia,nitrades and all of the important parameters that we have to take care.
We visited friends who have koi ponds and ask them but non is as comprehensive as what we have read in this forum. Intially we tested the water and the ph was 5.6 and after reading we added baking soda and how ph is at 7.5. Next step we will test ammonia and the rest.
We partioned a small portion of our pond also using pond liner with over flow to the main pond ( about 15% ) and put water lettuce in it, we also install a simple fibre filter in a proforated basket . Does water lettuce help in any way?
This is the first time we rear koi and once again we would let to thank all of you.
We will try and post the picture of our pond after my business trip to Thailand today.
The whole extension took us 3 days and after that the interior works goes on up to now.

Robert,
Nitrate is food for plant. water lettuce is good as it is "plant" and consume nitrate. Daily water change of 15% will also actually reduce nitrate but make sure your water is dechlorinated prior to enter the pond.

Hello Robert,

Welcome to the forum..... Water plants, in this case water lettuce, has its pros and cons when introducing them to the pond. On a positive side, it helps reduce nitrates, and also provides a more natural picture to your pond. On the down side, you might want to ensure 1st that the plants you will be introducing to your pond are free of parasites. These parasites tends breed and harbor their eggs on the roots or leafs of plants, and if unnoticed when moving the plants to a new environment would more often than not cause an outbreak of unwanted problems ranging from ich, arugus, water leach, blah, bla, blah.... Hope the info helps...

Dear Sunshinejoi

Thanks, Last night did a water change of more than 50% but when test the water Ph,nitrate & nitrite are ok but ammonia is still high .
I used simple test kit brought from fish shop.
Do you know anywhere i can get digital type.?
Thank again for the advice
We should go for tea with kit and the rest and talk more.

Robert,
Your bio bacteria could be lack of activity. May need a few more days/month to mature the bio filter. Add more aeration to the pond, 15% daily water change will help your nitrogen cycle.
Jalan Tutong, simpang 608 will be able to find digital PH reader. Havent seen any nitrite and nitrate meter in Brunei yet.
I am working in Seria, filtering oil.

Re: [Robert Lee] water condition [In reply to]	Can't Post

Hi Robert..

water change of 50% is very stressful to koi.. i would suggest u to provide 'house' for ur good bacteria to grow on, so far the best media for the job would be momotaro's bacteria house. u just need a high capacity water pump and flow the water through them, as simple as dat.. less maintanent n very effective..

ammonia high n zero nitrite n nitrate means ur bacteria need more time to grow , just as sunshinekoi mentioned. in ur case water plant is useless as nitrate is 0...

by the way, in case of emergency if ur ammonia or nitrite is very high..just dissolve 0.3% of salt in a bucket with fresh chlorine free water and pour the salt solution along the side of ur pond.. salt will reduce the toxicity of ammonia n nitrite..

hope the above information is very useful to u.. remember to ask any question u feels like asking as our brunei cifus like kemmer n sunshinekoi is always ard to help n share their knowledge.. Smile

will contact u for a cup of tea... by the way we always have some small gathering on sunday morning visiting pond, helping member clean filter, talk koi for the whole morning.. u r very welcome to join us if u r free..
u can click on my name 'koi@kit' and send me a Private Message of ur handphone number so can contact u easily..

Re: [koi@kit] water condition [In reply to]	Can't Post

Hi Kit,

When you menyioned .3% of salt do you mean compared to the water volume of the pond? and how many times can we do that as salt does not evoprate.
What type of salt? I used to by from the fish shop at Abdul Razak Complex and they cost B$3.00 per KG and when put in the pond they make the water blue.
Is this the correct salt.
I was reading forum from other regions and understand that Oyster shell does help PH buffer and from my trip to Bangkok last week and I managed to go to Pataya for a day trip and look back some oyster shells. I intent to put them at the filter tank this evening.
This Sunday I may be busy and sure would like to join you guys so that I can built a proper filteration system. After reading I think my filteration system is good for Longkan fish only.

Re: [Robert Lee] water condition [In reply to]	Can't Post

hi robert..
0.3% salt is the initial concentration u put into ur pond after dilute with water, as solid salt will cause 'burn' on ur koi.. and yes it is the concentration compare to ur water volume.. remember too much salt will kill ur 'good' bacteria in filter..
i dont add more salt after dat and as i flush my bottom drain or overflow my pond water i add in fresh water..

the salt i use is 250g small pack, i got them from AIKING at kiarong.. the salt is for cooking..

can u take picture of the salt u used that make ur water blue? it might not b suitable for pond use.. i m not sure..cud it be chlorine? Sly

where in abdul razak complex u got them?

yes oyster shell is for pH buffer.. but u must also consider the 'raise in hardness' after u use them.. i wud suggest u to go for momotaro Bacteria House which at this moment the best filter media in the market, why got for the old fashion when u can have the latest and best filter media.. Sly

dont say ur filter for 'longkang' fish.. if u willing to learn from ur mistake or others's mistake.. u sure will improve.. anyway nobody is the best in koi keeping, same for filter system.... always changes to get the best water for ur koi..

cheers

Hi Kit,

Is was nice of you to meet today Paul has mentioned to me when he said clay can help to lower the ammonia level of the pond and what is the name? forgot to write it down.
Tested ph is evening and ph has gone up to almost 9.
Ammonia is .8mg/l
Forgot to ask paul what is the dosage?

Re: [Robert Lee] water condition [In reply to]	Can't Post

Hi Robert..

aactually theres a lot of brand name for clay.. the one i m using is momotaro's "onitaiji".. the dosage for using this type of water purifyer is 1cup for 10ton of water.. over use causes no harm...

i dont understand how can ur pH go soo high.. usually pond made of cement wil have this type of problem, since urs is made of liner, i wonder where the buffer stuffs come from... what u can do is to add diluted vinegar to ur pond slowly to reduce the alkalinity.. get a bucket n put a cup of vinegar in, then dilute the vinegar with ur pond water.. then pour the diluted vinegar to the side of ur pond slowly.. then check ur pH again in abt 1 hr time... high pH dont kill koi but fluctuation of pH can b deadly.. if morning shows 7.0 then evening shows 8.0.... dis can be deadly..

its my pleasure to know u and realise how crazy u r abt koi Sly

cheers

Hi Kit ,

Thanks any equipment or chemical to measure salt content in the pond and what shuold be the reading?
Show the salt to Pual and he said the salt is good and on the recommendation printed it say one teaspoon to 20 litres.
I am going to Sg.Tujoh for a inspection you are right might just pop over after all i will be very near to Miri.

hi robert..

yes i heard the salt is good as it said 'anti bacteria'... but if i were u i wont use it too often coz 'anti bacteria' means it will kill ur 'bad' and also 'good' bacteria.. then forever ur water will have high ammonia wothout the good bacteria..

if u can find the uv light bulb, do u mind to buy for me 2 pc? dont mind to keep spare... many tks..

Re: [Robert Lee] water condition [In reply to]	Can't Post

Hello,

How's oil filtering going on?
Now I know that my filteration system does not allow the bacteria to grow because I change and clean the filters everday. I created a secondary filter basket and will not clean that one for at least 30 days so that the bacteria can grow.
I visited a friend last months and now remember he told to creat a overflow pipe and leave the water from the tap on all the time ( small amount ) so that the ammonia can be drained constantly. Is it correct?

Re: [Robert Lee] water condition [In reply to]	Can't Post

hi robert..

leaving a basket with ur special sponge for 30days will still not allowed any bacteria to grow on.. bacteria need a special home (filter media) to grow and multiply.. Laugh

yes ur fren is rite, by overflowing a small amount of ur pond water will reduce ammonia safely without stressing ur koi and also will remove surface oil or dust..

Hi Kit,

Remember I told that i have a friend that keeps almost 200 kois in one pond? Went to visit his pond this afternoon and the water stings. Called him to change water of 15% to 30% as per advice given to me by members of this forum.
I will testing his pond water tomorrow and the result so that all the cifus can help me to help him.

hi robert..

dats a good advice u give to ur fren.. soon i ave to call u cifu oredi hehehehehhehhhe

yes checking the water parameter will easily find out the problem of the water condition..

sometime when the water smells, its beoze the filter is overload with koi waste, by cleaning the filter and make water change can reduce the smells..

how abt ur ammonia problem? u have added the onitaiji? wats the reading rite now?

Dear Kit,

In orderto become sifu is still a long way to go and needs people like you. I have treated the pond with the clay and the ammonia reading the morning after was 0.4mg/l and since have not tested. We have increased the water level by another six to eight inches in our pond and the fishes seems more willingly go to the upper part now. Is it because they sense the depth?

Re: [Robert Lee] water condition [In reply to]	Can't Post

morning robert..

so the clay do reduce ammonia.. what was ur previous reading? how abt ur pH?

increase pond dept will increase the volume of water, dont think will effect the koi behaviour.. by the way ur koi all look very healthy especially when food touched the water hahahhahahahahha..
the koi willingness to surface might be the result of reduced ammonia..

very well done..
