I set up a 34 gallon cube as a mostly SPS tank. On my 300 gallon SPS, I used to dose BRS 2 part and everything thrived. That tank has been converted to a peacock cichlid tank, but I still have the Apex Neptune and BRS dosers. I'm running the AN on the new tank, and I was planning on using 2 part, but then I saw All for Reef. Is it better to use AFR or the 2 part? I do a weekly 5 gallon water change and use Fritz RPM for salt. Any help would be greatly appreciated!
