Hi fellow Reefers on this last day of NOV, @vetteguy53081 and others, what is a recommended alternative to Red Sea Reef AB+ that I can use in a doser long term? I honestly just read a reply from BRS to myself that RedSea is only good for 7 days unrefrigerated...well I know I have mine in my doser for about 3 weeks now...which means it (Reef AB+) more than likely is no good. What are your recommendations? Corals look fine, however, my phosphates are around .13ppm, and Nitrates has been steady at 40 ppm (API test) for 2 months now.
