I like them a lot. Coming from using Hydra 32HD's. The growth in this new tank is a lot better. I run them on a lower PAR level than my Hydras and I'm getting great coloration and growth. I do think further down the line I may have to add a couple more or run some blades to help once corals get bigger.Nice! This is my backup plan if I can't figure out a way to attach the fixture. Tank is in place so not much room for construction...
How do you like the xr15s?
