Wave makers

[Bremenguppie]

I've got two wave makers that produce 528gph. In my 30 gal tank it seemed fine. I just picked up a 75 gallon. Curious if they would still be big enough for 75 gallon or do I need something bigger and if so what GPH number should I be looking for.

It really depends on what you have in the tank. If it's fish only, sure, that will work. If you're keeping SPS, you are definitely going to need more.

Typically you want 20-30x display tank size in GPH for lower flow tanks..
40-50x medium flow... 60-100x for high flow

So you really need at least 75 x 20 = 1500 to 75 x 30 = 2250 GPH
