I seen a maxijet natural wavemaker system, it has 3 maxijet powerheads and a wavemaker, does anyone know about this? Now this has all 3 Maxijets at the same GPH from 400 to 1200, so you can not buy different GPH rates for you powerheads when they are grouped with this, is that O.K. because from what I have read everyone has different rates for each powerhead in there tanks. Are Maxijets good? I am torn between them and the Koralias what would be better, the Maxijets are cheaper and that is a plus, I want something dependable and works of course.
