So after wondering why my corals weren't growing or coloring well I broke down and bought a par meter. Best investment I've done. If your not sure what quality of lighting your under rent buy borrow or steal a par meter. I was running 3 hydra 26 10 inches off water. I was barely getting 200 on top ledges. I have added a 175w mh and 2 hydra 52 and finally getting the numbers my SPs need. Anyone need a reading I would be happy to help out.
