I’ve got a 68 gal aquarium setup as a mixed reef. I’ve got 1 MP40 but want to add a second Wavemaker to prevent the flow from all being in one direction. The tank is 36x21x24. Should I get another MP40 or add a gyre xf330. I’ve got an apex if that makes a difference. I’d like to spend less if possible, so if there are other reliable options I’d be open to consider them as wel.
