I've been in the hobby for 3-4 years now and ive always had a GFO reactor. i've never had any algae in my tanks . but I've always never had corals color up like i see in pictures. i heard horror stories of people shutting down Biopellets reactors. is it safe just to stop using GFO cold turkey ? or should it be a gradual thing ? anyone have any experience ? wanted to try not using GFO and seeing if my SPS would color on up.
thanks for all the help !
