Hey everyone. I'm curious to see what anyone has to say about the lowest they've seen their salinity in their tank with corals still thriving? I recently realized my tank was running at 1.020 for quite a long period of time. Verified by 2 separate digital Milwaukee checkers. I've since brought it back up to 1.026 and have seen a huge improvement but things were actually living and growing at 1.020 including sps.
