Not really. Its not as much as you think. I have clowns, firefish and a goby. For corals I have zoas, acans, duncans, frogspawn, kenya tree, shrooms, and a bunch more. The frogspawn and tree barely move in the current. I have one on each side aiming towards the front center.
2 1200s is only 590 gph. Thats less than 20 x my tank volume. Ive seen 30x even 40x times the tank volume.
