Never had one before. I have a 20 gallon high. Is that too small of a tank for one? Only 2 feet long
Honestly , just cuz I like the shimmer in the lights you get. But I’m all for the other benefits tooYes, they sell powerheads/wave makers for nano tanks. I think you can get them pretty much anywhere. At least Amazon and Ebay.
I bought one for about $10 just to circulate the CO2 in my 20 long. Works just fine.
Why are you looking for one?
