Ok...been reading about lighting and have no clue. We have a 25g bow front tank. We have a lighting unit with two bulbs that come in the same time. 2p-9p. White- t5 HO
10000k 18w BA
Blue- t5 HO
420/460 18w WAC
Tis is what the guy st the store tild us to get. At first we just had a royal gramma, goby, 2 chromis and shrimp. We recently added a GSP, red mushroom & green fuzzy mushroom corals. People keep talking about moon lights and LEDs....do we need those ? Do we need to add another unit like we have or are we ok?
