I'm surprised this is working for you. I lost 4or 5 nice colonies over a few months when my SG crept down to 1.023 because of a bad refractometer that was reading +.005. In my experience refractometers tend to creep up when not calibrated so I aim high at 1.028 to avoid going to low.My salinity is 1.023 never had no problems and corals grow like weeds. Been doing this for over 20 years. Different strokes for different folks that’s what makes this hobby great.
