Update on the "indoor pond/swimming pool" - pictur

[oenology]

As some of you know and as some of you have seen I have a 12 foot diameter inflatable pool in my basement. This is the kind with the inflatable ring at the top of the wall. So far so good. I have about 40 goldfish a varying sizes from this year's spawns to fantails that are a couple years old and a few sarrasins that are about 8". I have a "black box" pond filter powered by a 901 powerhead for filtration. So far I have only lost 2 very small fish. Everyone else seems fine. I feed them maybe 5 times per week and not a lot when I do. The basement is sort of heated as it's more of a hunch space where the furnace is located. There doesn't seem to be any issues with humidity down there. In fact there is less humidity there than in the house with all my tanks
