check salinity....what do you use to measure your salinity

 

all my tank par are good..i have alot of tests and i kow what they should be...my tank is a 40 gallon with a 15gallon overflow 2 power heads,1 clown,1pj card,1 scop tang 1 green goby...2 96watt coralife lightsat 10,000k one is abtinic blue....no bugs or nudis...the tank is 17in tall and 3ft wide..i use a hydro meter for salinity and its around 1.023

 

Zoas are very hardy. Did you try doing a couple of water changes.

If all your parameters are right then the tank could be contaminated with something toxic.

 

I had some die off till someone asked if I was feeding them. Then I started using the DTs and they came back double time.
