While they may not be ideal, I do get a decent amount of growth with them and if I move them to close it will turn the algae yellow. I know I could get better coverage with t5's or LED's so I might look into a cost/benefit analysis. And running a 02 sensor would help prove what light is best and if CFL's are sufficient.
