I have several planted tanks and really like the Finnex lights. I'm now starting a 55 for a Jack Dempsey, which means no plants, and I'm wondering what lights to go with specifically to prevent algae but also make the fish look good. Would a stingray still be too much? Should I stick with the stock 2 18" t8(after being used to my planted tanks this looks extremely dim, but maybe that's a good thing)?
