Hey Bud, good so far, and welcom to the boards. OK a few things, on a bucket I just flushed and filled last night the water temps were about 59F and didn't have a problem, under 57ish is pushing it, but as someone said a aquarium heater is something that can help raise temps and there are fairly cheap. It seems like allot of buckets for that light, but I think that you will do good, and have a good experience.
Oops, have to get off, will fenish later.
Adieu
