Just my 2 cents, but I am hesitant to add any nutrients to my tanks (besides food of course). I always seem to be battling algae, which I control with GFO reactors, heavy protein skimming, an Algae Turf Scrubber in one tank, and vinegar doing in the other. Once I am truly confident that algae is under control, I would definitely like to explore things like Red Sea Reef Foundation ABC+, but until then I'm going to play it safe.
