    Check ph, ammonia, nitrate , nitrite. The salt the pond. Wait for a week or two. Then add fish. Care to show your pond layout?

    ChengAun,
    Thanks for your quick respond. I have attached my pond, please feel free to comment. Any advise will be grateful. The size 78x52x36(depth) inches. The filter measures 12x20 inches and partially eats into the pond. Can you state in details about checking ph, amonia, etc. How to to this? is there a tool/meter? How to salt the pond? I am totally new to breeding koi.

    Hi David,
    From the picture, it seems you have not coated the pond, and it is bare cement/concrete from the picture. My advice would be to fill it up with water, and let all the toxic/poison from construction of the pond clear out to run in the pond. You may want to clean up using a brush or anything to rid of the excess cement. I would run it in for a week, if not longer (this is a good time to add in all your new filter medias or anything you plan on putting in your filter to run it in). Empty the pond and fill it up with water again. Most importantly add beneficial bacteria, dose it a good amount. If you are still unsure, I would put in tester fish to make sure it can survive for 2-3 days.

    For startup, you may go find aquarium salt to add into you pond (make sure it is not iodized salt as this is basically poison for fish), add increments of salt until it reaches .3% in the space of 3-5 days. Never throw salt into the pond directly, make sure to mix it with a bucket of water and allow it to dissolve completely before adding the mixture into your filter, if you use bay filters, put it into the first one.
    You buy salt measures from most koi shops.

    Ashfaq,
    Thanks your your tips, they sure help me understand better. I did not water-proof my pond, my contractor says it is not necessary. The walls and bottom are already with 5 inches concrete and plastered with cement. How do I determine the tonnage(amount of water) in my pond? You mention .3%, so I need to know amount of water my tank can hold. My pond is 78x52x36(depth) inches. The filter measures 12x20 inches and partially eats into the pond.

    Thanks again.

    I would cycle this pond for 2-3 wks before doing anything. Also put in some small fish and see how the fare. When I started my pond, after cycling for 1 wk and throwing in some small fish, all of them kaput. I cycled the pond for another wk and threw in another batch of small fish which survived happily and procreated, indicating all clear to load up.

    Wongyeng,
    Many thanks. But first , Ineed to know how to calculate the amount of water my pond can hold. Then only I can put in the necessary salts. Can you tell me how to calculate. BTW, the salt is the type that is sold at sudnry shop(coarse type)?

    Hello David,
    Here is the calculation :
    6.5ft x 4.33ft x 3ft = 84.44 cubic feet / 35.315 = 2.39 cubic metres. (1cbm=1ton)
    6.5ft x 1ft x 1.67ft x ft = 0.30 CBM.
    Total Tonnage = 2.69
    You will require less than 9 Kgs of salt for your pond to achieve salinity of 0.3%.

    I would suggest raring goldfish, as koi require more space for growth!

    Kaaj,
    Thanks for the calculation. Anyway, I tested my pond and found it to be leaking water. Overnight, half the water laeked out. I did not water-proof my pond. Now, I need to
    get my contractor to hack off the surface cement plaster and apply with water-proof cement plaster.

    Adlee/Idris,
    you are both right. It seems my contractor forgot to add in the water-proof milk when he plaster the cement. Now it will cost me more to hack-off the layer of cement and replaster with waterproof milk. The water seems to hold at about 1 feet deep. At least the bottom floor is not leaking. I have been refilling with water and I believe the leak is some where between 12" to 16" height.

    Is there any piping at the 12" to 16" height? Most leaks are from the pipes.
    Don't ask me why!!!

    David333, when your contractor is plastering, do request them to round up all the corners to 5" each side, bottom 90 degree corner as well.

    Bro david, ya bro Mike is correct. 90 degree joint where two walls meet or wall & slab meet are always the weakest places and leak the most. If you decided to hack away the plaster surface, suggest to do up the angle filler before apply the water proofing. Hope it helps. With half of pond water gone overnight, think the structure might have some cracks or as other bros suggested leak at the pipes.
