I grabbed it from a thread in the Neptune forum on RC.

I have two koralias (1400s I think) in a 6 hour alternating mode (with the koralia "wave" controller) in my 72x18x18 tank. I find that it works pretty good. I've thought about putting a tiny powerhead in the back on the tank.

Are tunzes way better? They are a lot more money. Is getting a push pull action also worth it? I've got some begginner sps and softies.

Tunzes are way better, due to their ability to pulse. Does the benefit of having this control outweigh the high price? Depends on what you need/want in your tank.

However, as long as you have decent random flow in your tank, you're probably good spending your money on something else :)

Thanks.
