I have had some recent issues with my tank since I added a Powder Brown Tang. I did not QT tang but slowly acclimated. He then contracted ich and this has spread to almost all other fish. I started to feed Dr Gs Anti parasitic caviar. All was well but woke to find him dead yesterday and today I had a damsel and seahorse pass. I'm thinking this might be Brook. Please help. I have had these fish for years and never had issues. They are still eating and acting somewhat normal.
Keep in mind I have a reef tank that is 120 gallons with live rock so catching fish is nearly impossible. Also I recently dosed Kalkwasser on a drip....not sure if this made things worse.
Ph 8.3
Nitrate >10
Phosphate 0
dkH 12
Calcium 300 ppm trying to fix this
Salinity 1.023
Temp varies 76-79
