Pond first fill Can't Post

Hi guys,

The construction of my new first pond has been completed and almost all the equipment has been installed. Other than water, everything else is already there. I have received some advice on the steps of filling the pond for the first time but I would just like to get some more experts' advice here on the most proper way of commissioning the pond before it will finally be ready for me to start put the first fish in, especially on the step-by-step filling and the duration of each stages. Thanks!

FYI, here's the specs of my pond:

Main pond 8' length x 4' wide x 4' deep (concrete with outer pebble wash finishing, with 1.5' raised wall)
Main pond -> sediment chamber -> mechanical filter chamber (brushes) -> japanese mats -> pump chamber (with coral stones) -> bakki shower
cw overflow line, skimmer, air lines in filter chambers & main pond, top up line, drain lines, underwater jetting etc.

dont ever get fish yet!! seriously..wait until at least a month.
here in malaysia is once ur overly-confident that no cement residue or soil and stuff like tha is in yhour system, what we do fill up the pond and put in slices of pineapple, its said to neutralise all the contrustion chemicals and cement so itll be more suitable.
you need to fill in and flush again a lot of times, but once ure done wiht that, the final water should be added with anti-chlorine, let the system flow, then the next day dump in a bio-kick/starter/good bacteria in your bio filter. let the whole system run for a month, lonegr of course better. then happy koing!!

Tancho_boy,

Thanks for the advice. Yes, one month I can do, but I'm sure the agony of waiting can be severely unbearable at times... LaughLaughLaugh

I have been advised to use cooking vinegar to neutralize the construction chemicals. I suppose they have the same effect of sliced pineapple but with this, you at least don't have to fish out the pineapple slices later.

When you mention, "fill in and flush again a lot of times" do you mean total flushing? And how many times at least? I was thinking of only once total flushing and the rest are more of partial flushing and topping up. 3,600+ litre is a lot of water and it seems like quite a waste to dump all those water despite water in Selangor will be FOC! But in any case, if total flushing is really required for the happiness of the fish, I'm willing!

Lastly, do you really need anti-chlorine? Wouldn't exposure of the water during the holding cycle will evaporate the chlorine out? Besides, I'm putting "suicide squad" in first to trigger the nitrogen cycle and hope they survive the chlorinated water.

Thanks again for your time to provide the valuable advice!

Re: [PO] Pond first fill [In reply to] Can't Post

yipey for ts khalid. but only rm 11 free, rest have to pay. well i think u would understand my advise on flushing as many as u could afford. see the thing is not the see-able area of the pond that we're concern about, its rather the pipings and drains. for me, its better to be thorough than having something cropping up once the fishes are in, cus it would be heck of a trouble then if u have problem later to drain. well yours is not big of a volume, i guess its really worth trying. plus one thing i would recommend if u havent finished the pond and to others that might be reading this, if u drain your pond with pumps, normally people use something like a lever or water switch to allow water to enter pond or to drainage (longkang), i suggest pumping the not-usable water to a tangki, so water wont be wasted. u can keep the water, later when u have fish, its free fertilised water AS WELL (nitrates are good for plants)!! problem with this idea tho is the unsightly view of the container/tangki. if u can manage to hide well, then it be good for the conservasion as well.

the idea with either pineapples or vinegar is the acidic nature. i dun really know how that reduces the chemicals from construction, but we'll go with it. but that acidic water MUST be drain, cus kois suit better with ph 7-8/lower alkali. some say slight acidic is good for sumi/black - showas and utsuris, but thats for another discussion. let the acidic water soak up for 2-3 days, what the indons did for me was doing the acidic and draining twice. so thats close to week. patience is the key here fren!!

well i suggest anti-cholrine namely for the bio-filter. u see, once ur confident of pond free from debris, presence of chlorine will kill nitrobactors, so if u add bio-start to your filter (either coral or bio-bhips/rings or mats) itll be quite wasteful. to what extend i dunno. plus itll take about a week for chlorine to evaporate depending on depth of pond and weather. so for your size 2 rm5 big bottle of anti-chlorine is really worth it. if u decide on putting anti-chlorine, ler the whole pump system run overnight so ur sure no chlorine, then add bio-start.

thing about the nitrobactors, it does take awhile for them to really colonise maturely. some say a year. i tell u my hard learned experience. a week after all the draining out process on my pond, we went to sik kedah koi farm and got 30 kois, 20-cm. i was told, rightfully so, to start with local kois. at least IF anything happens, not much waste la- money or tears, becos once u go jap u never turn back!! we have a 16k L pond, inc filters, so thats really overstocking. so within a week my water turn green, next week only 5 of 30 survived!!! then i also learned things about medication after that, but again thats another story. ive learned how to overstock now, u can, but maybe later2 i tell u more secret ok..

i suggest if u really have itchy feet, get a few kois at start. maybe 2-3, to get shit to feed the nitrobactors. other than that please please wait before u buy ok. sincerest of advise. some say u have to wait 2 months from start when u put in bio-start. PATIENCE IS THE KEY HERE FREN!!!!!! HAPPY KOING!!

maybe we'll bump during the weekend at the mid valley koi show....

tancho_boy,

Thanks for the advice. I did exactly as you said. After a couple of days my pond has managed to reach a stable 7.8 pH reading. The high alkaline reading earlier must have come from the concrete dust. A few bottles of cooking vinegar and a few flushes seems to do the job just fine. Later I added a bottle of anti-chlorine and the water looks just as clear. Yesterday I have put in the suicide squad (6 of them from Jalan Pasar Pudu ranging from RM1.50 to RM5.00!) to kick start the nitrogen cycle. The squad looks happy and they started feeding today and hopefully be shitting soon and feed the nitrobactors... Tongue. I will give them a month or more, at least, before I put the real expensive ones in.

I'm still waiting to hear on your "overstocking tips"! Wink

By the way, sadly, I missed the Koi Show in Mid Valley because I was busy moving house. I heard it was great. Unsure Maybe next time, eh...

Re: [PO] Pond first fill [In reply to] Can't Post

overstocking ay??.. the rule of thumb is roughly a comfortable 2k L per fish..thinking ahead. that is for a koi to grow comfortably the density should be that. but i guess if ur starting off with tosai's 20-30 cm ones, your pond would seem pretty empty (remind me..yours is a 13 tonne rite?). so 6 fish in a 13 K is only nice if u have large 70cm plus kois. so i must admit, the temptation is ALWAYS there to overstock.

few things ive learned about coping with overstocking- ie cleaning/collecting as much koi poop in limited filter:

1)fast pump flow/rate.
this works well regardless if ur overstocing or not. normally the advise is once per 2 hours or so. im doing 30k L per hour in my 16k L pond, give and take that should give me about one cycle per half an hour. good thing about this is a lot more than the bad.
good - faster rate to filter, thus more shit in filter. some say that there must be a certain contact time between water and the nitrobactors, so to convert them efficiently. but i think regardless of that theory, even if water passes tru bio media faster, water still comes back to bio media more totalling up. so for me i makes more sense to get faster rate because, as most ponds in malaysia are design, the bulk of koi poop is mainly collected at settlemet chambers and mech filters. PLUS, a vigorous water flow in your pond is actually good for koi. kois are naturally river fish, so water is fast flowing. so a faster pump rate would somehow e quite benficial to kois. the design of ponds in UK and Japan that uses the Bakki shower is that water inflow is only from one point of entry and exit is through one, so this creates a one-way current to develop body shape. Momotaro uses this design. Plus faster rate provides more oxygen. i dont use an aerator, ESPECIALLY not in the filter (to allow settelement). i use to though.
bad - quite costly, but for me the price difference between a 10k L/h and 20k L/h pum is worth it,but the operating cost is between the 2 is very different. on the long run this method is costly, but this is not a cheap hobby. another bad thing about having fast pump rates are the amount of poop in your sttlement chamber. this is of course good, but u have to have regular cleaning routine, once in 2 weeks flush out. new water is also good for koi nevertheless.

2) PP bombing
i have only tried it 3 times. i have read that PP is actually good for colour of koi, but for me this is just say and non-proven. but PP does clean up organic matter quite fast and efficiently. koi keepers in the west especially like this method, PP is quite cheap, and once u'v mastered the technic it really beats cleaning up. i only use like once in 6 months, mainly for any parasites, not really for cleaning up.

3) Water supplements
this is very very costly in the long run. products which help u reduce ammonia nitrites nitrates etc do help you out if ur overstocking. i only use kasuri clay, mainly for the koi rather than cleaning up, but kasuri clay does clump up debrise together so that it is heavier for settlement.

4) Bakki shower/ TT
i have read that towers with the right flo rate is good for overtocking. but for me, tower's main purpose is to reduce nitrates.

Re: [tancho_boy] Pond first fill [In reply to] Can't Post

tancho_boy, I'm embarassed to even mention my pond size here Blush, compared with all you seasoned players. I would call it a "compact" pond, meant for front porch of an intermediate unit of a linked house like mine. I posted my specs earlier: Main pond 8' length x 4' wide x 4' deep (concrete with outer pebble wash finishing, with 1.5' raised wall)
Main pond -> sediment chamber -> mechanical filter chamber (brushes) -> japanese mats -> pump chamber (with coral stones) -> bakki shower
cw overflow line, skimmer, air lines in filter chambers & main pond, top up line, drain lines, underwater jetting etc.
That would give me 3.6 ton for main pond (4.5 ton if include the filter chambers). That means, by your rule, I can only keep 2 kois! Unsure But I hope with the ample filtration system and the bakki shower, I would be forgiven by my kois if I were to "overstock" a bit...Crazy An enthusiast once looked at my pond and told me with the size I have, and the filtration system I use, I should be able to keep 6 full grown ones the most. Hope he's right. (For now I'm just starting up and only have 6 little local kois that make up the "suicide squad" in there). I do keep close watch on the water parameters though. Wish me luck?

Re: [PO] Pond first fill [In reply to] Can't Post

the best thing of koi keeping is, your own satisfaction, from designing the pond, taking care of water (more important than taking care of koi), learning along the way how your koi develops. but im sure, all of us regardless of pond size when water is clear, kois are active, would enjoy the quite time by the pond feeding our fishes :)
BUT of course all of this you enjoy until you go to koi shows!! like the feeling i had at mid valley!! frust man! most of the kois are kept at bigger ponds, some keep it at YTL's janda baik. even kepong koi and atari keeps a huge concrete pond for their customers. it takes a lot to grow competition level koi. but i love my kois nonetheless. 2 of my local koi are growing really fast! but maybe thats because its from a chagoi line i presume. i bought 2 50cms from shah alam (xiang leng) for rm 250 a piece- which claims to be imported- yeah from taiwan maybe! nice colours but only the asagi is growing, the showa though i lke the pattern is stagnant.
then after i was quite confident with my water quality, i went to kepong, got a deal with them bought 5 kois for total of rm 1500, although they were all males. males are not fast growers, but i do see them grow regardless. my largest koi should be aroung 60 cm now. dont think they ever grow beyond 70 in my pond. but i love my kois.
it all depends on what you want really. some are really up for it to go for sizes. sizes u need good bloodline, nonetheless. some go for different types - im looking at getting a shiro!! with the right price la. gila when sentul koi were selling omosako shiro utsuris for rm 3k each at tosai!! that for me is gila, at my current pay la at least. spend so much also cannot, unless uve spent on our pond.
so all and all i can definitely say enjoy what u have, regardless of what temptations are out there! ;)

Yup. Agree with you. No matter what others might say, as far as I'm concern, my pond is THE BEST. And my kois are the most beautiful ones! Wink
Thanks for all your help. I'm done with all the setup including the bakki shower and they are running just fine. The first 6 kois are swimming happily in the pond.

Now, the waiting part... Cool

Smile agree with both of you ! My new pond will be ready soon too, after demolishing my old 8'x6'x2.5' pond, new pond will be 15'x9'x4.5', hopefully all my 11 kois' will be happy with their new home..

hey chanys, most important about designing/building new pond is always your bottom drain, cus thats where most of the poop will flow through. hope it turns out great ;)

Hi Tancho boy,

I have just bought 2 little omosako shiro from Patrick Chia in kepong.. price reasonable unlike in sentul. You can call him at 0122322820. Still plenty to choose from, just arrived last week.

Regards..Wink
