Waiting for Instant Ocean Regular and Coralife to arrive and will post results soon. I have been testing different salt brands myself after getting a real bad batch of Reef Crystals. I used them for years with success but I changed salts after these results. I also found my Hanna Calcium checker to be off by 100. I have Red Sea and API test kits on hand to verify when I have off the wall results.

Mixed Reefer 450, Lifereef skimmer, APEX, GYRE 150, Jebao DCP 10,000 return pump, BRS dual media reactor, Kessil 360 lights, Coralife Reef Salt.

Current Tank Info: Red Sea Reefer 450
