Re: [kianliang87] Preparing a new pond with good water quality.
[In reply to]
I'm a newbie in KOI hobby and also new to this forum. I have some questions about preparing a new pond with good water quality.
First of all, the newly built pond is a concrete pond which will leech large amount of high PH right?
So my question is, how do we cycle this tank until the PH stabilize to a level which it will not harm the KOI?
I've seen few different methods, vinegar, pineapple, acid. Can anyone tell me what is the advantages and disadvantages of the methods? As far as i know acid is the cheapest method and has the lowest PH comparing to the rest. But i'm not sure if it is safe. Please help.
The first and formost is to be patient. Often than not, people (me included when I first got started) will always rush in things, and before we realized what's happening, the Kois are in the pond and 1001 problems will occur. So let's start from the beginning, yes you are correct that a freshly made concrete pond will cause the pH to be high i.e. very alkaline. Also the toxic stuff that are in the cement are also lethal to the kois. You would want to get rid of these first! Yes, go ahead and buy enough pineapples and start to rub them on the surfaces of your pond. Sure, it is cumbersome but this will be good for your pond going forward. The banana trunks chop up in chunks will be OK too after this i.e. soak it when you put in your water in the pond. Another alternative is to get rice vinegar (these are very cheap actually), well as a yard stick, one bottle per ton/2 ton of water. Let it sit for 3 to 5 days or even 7 days. This will do wonders to your pond.....thrust me on this! After that drained all of the water, host down the pond surface and clean thoroughly! Then fill your pond with water. This next step is entirely my own and it is up to you to follow or not! It is up to you! Most new pond has a lot of parasites and bacterias that are unknown to us. Not treating this will eventually affect the new introduce kois one way of the other. At this point I would bomb the pond with PP (Potassium Permanganate) at a rate of 3mg per ton of water. Let the water sits for 6 to 8 hours, give it a further 2 additional hours, add at least 0.3% salt to the pond. My recommendation is 0.6% salt. By doing the PP and the salt, it will take care of most of the parasites and the bacterias. At this time I do not wish to be very technical as this will further create confusion. I recommend that after a further 3 - 5 days, drop the water by 50% and top up with fresh water from the tap. Don't forget to put anti chlorine and water conditioner at this point. Give yourself 24 hours, and check the water parameters i.e. pH, Ammonia, Nitrite, Nitrate and kH. The reading at this point should be within acceptable range. Then get one or two local kois (you need to ensure that these are being quarantine already) and put them into the pond. Watch the behavior and on the third day, feed these two fishes sparringly! Just feed a little bit only! You only need a little feaces and waste products to jump start your filter. This is also the right time to introduce nitrosomonas and nitrobacter into your biological filter........At this stage and when you introduce the Nishikigoi, you would want to check the water parameters as frequent as you can.
Hope this helps!
