Let me tell yall, I was on the brink of throwing in! So I just got done with a dino blackout last week and have been free since and everything was looking great except low levels of ca,mg,alk. I wanted to get the tank perfect for my fish babies to go back in and decided to thoroughly inspect and clean all equipment. Took out the refractometer and I was going to calibrate it but didn't have any solution so I made some and my tank was reading 1.010! I couldn't believe it so I went and bought some calibration solution and sure enough, 1.010. I haven't calibrated for atleast 6-8 months!!! How have my fish and corals been alive? I believe this was the reasoning behind dinos!!! Thoughts?
