I have a 75 gal with a 20 gal sump. I have a 48 inch dual Aquatic life T5 with a 54 watt Hexarc ocean blue and a 460nm bulbs. I bought a frogspawn frag with 2 heads about two weeks ago and it looked good. Now it's starting to look a little limp and not as bright. What can i do to bring it back to its bright and full flowing state?
