Anubias;3878433; said:I've been using a small "doughnut" pool this winter to temporarily house my koi and goldfish while the pond is rebuilt. I haven't had any problems, I do have a 1500 watt heater to keep the surface open. We have had some cold weather (15 was the low last night) but I haven't seen any ill affects. I plan to use it for some rainbows this summer after the pond is finished.
