I've had them running since last September. I could probably have turned them up more but I wanted take my time and not bleach anything our. These lights can get pretty darn bright and really toast some corals.
i have recently had some sps bleaching but not sure whats ausing it. i have 2 radion pros and 2 mp 40 with 2 part dosing brs. I jus started adding lugol iodine drops hoping this will corect the problem. I dont have much experience and am concerned it might over dose. anyone adding the iodine?
