I just got another powerhead total of 2, Where should I position them?
I think my bubble coral is dead
only a couple of polyps left, im hoping I can save it, I will show you pics, I think I have to move my Zoo's there on top right now and I just switched to a t5 light.
Im also thinking of replacing my sand bed but im not sure if I should go shallow bed 2" or DSB 4.5"
