I switched from Acropower to easy reefs sps Evo and it made a huge difference for all of my sps.Hmm, I have three med/large frags. Well, they're mine but babysitting in case an extended tank move has issues but mine to keep if no issues. Playing around with placement, low, med, high PAR. Most are fairly pale compared to others here. Will be interesting to see if some added blue spectrum will help. Just started Acro Power too.
