I bought a wave 2k, but decided to sell it rather than use it. The tank I saw it in, it worked great (180), but I wanted to put it in a 90 gallon. For me, the W2K took up way too much room in the tank. You might want to check their website and try to get product dimensions. IMO, if you don't like powerheads in the tank, you won't be able to stand how big the W2K is.
