I have 2 tanks I'm looking for good plant lights for: A 38 gallon bowfront, 23" tall (about 21" from surface to substrate). I currently have a beamswork fixture on it, but due to the depth I don't know if it is enough. I keep low light plants in it. Many of the plants have bottoms that are losing leaves and/or turning brown, specifically ludwigia repens and moneywort. Also the shorter plants don't seem to be doing well. I am looking at finnex lights, specifically the planted 24/7 plus (what's the difference in the SE model?) and the ray2. The ray 2 is high output it says, but not dimmable as far as I can tell, and I don't want it to burn the plants or cause an algae explosion. But will the 24/7 be enough to get to the bottom of the tank? I am also building a planted 40 breeder and am considering a 24/7 on this tank. All in all I'm looking at the 24/7& SE, fugeray planted plus, and the ray2. I would really appreciate any help with this.
