What are considered the best wave generators? I currently have a 75gal mixed reef tank w/ 3 koralia circulators (#4, #3, and #1) as well as a fluval 305 canister filter. Lots of flow and some variation due to wall reflections etc. but not really waves. I was looking around and found a Red Sea Wavemaster but I understand it would kill my Koralias in short order - although supposedly there is a "Koralia mod" - anyone know what this is? Suggestions?
