I have a single regular prime over a jbj frag tank about 14" over it. Surprisingly I have a setosa, birdsnest and had another acro growing. Not quite as fast as I'd like, but, had I used the ai mount it probably would've been better. Soft and lps are fine. Imo, sticks would do ok if placed appropiately and acclimated. Fwiw I'm running everything but Uv ,red,green at 100%
