john C;2994887; said:paint is cured and not in direct contact with water probably not it. foam top not sure but i probably not. i think you are in the right direction pond is not cycled. i had a power outage last year and 48 hr later got generator and ammonia spiked over 2ppm. with many water changes and about 2 weeks later water back to normal. keep up with water changes and feed very lite. i feel your stress good luck
Paint is ruled out, I called the manufacturer, no ammonia, fungicide, bacteriocide (word?), mildewcides (word?)...
This is text book, tested the ammonia this morning, day 14 and it is 0ppm!!! This means that either: it was a cycle; or the lids I removed 2 days ago (with the insulation) were the problem; or the 6 cyled Hydrosponge V's that I added 2 days ago did the trick.
I think that it was a cycle, next pond will be isolated and cycled fishless.
I am continuing with daily w/c's and very light feedings. Rays are getting pissed about the feedings though!
