So a long story short I did something stupid to my tank was my fault not checking a test kit that was expired and was dosing sodium nitrate so it kept reading zero or 1 and I kept adding it lol, they got up to 80 and a lot of my zoas took a hit, a lot of them lost color and are not fully open there like 75% open, will they ever recover it's been about 3 or 4 weeks parameters have been corrected since then. My sunny d's colony was so nice now there only 75% open ive tried everything for them to open back up and nothing has worked.
