I will be receiving an IM INT 200 peninsula tank in a few months. Dimension is 70 x 30 x 22. I originally thought 4 hydra 26 / 32 will be enough since most of the corals will be placed in the middle of the peninsula. And my research says more smaller fixtures is better than fewer but bigger fixtures for spread coverage. Now I am starting to think I need 3 hydra 52 / 64 instead because of the 30" wide. This will be mixed reef with SPS and LPS. Will the 26 / 32 be sufficient or should I just cough up the money now for the 64s?
