My Quarantine tank and Hospital tank are separate tanks. I initially have a 40W 10,000K MH LED over a 20 g hospital tank. Right now I have a Radion G1. That was what I used to treat my Magnifica and Haddoni. I am building a 300 g reef tank (Got 4 Radion for this tank to be build. I just wrote a check for the tank today actually).
Once the fishroom with the 300 g tank finish, I will have a AquaSun 150 W DE MH over a 20 g tank for hospital tank. I have and will continue to use a Aquapod 29 (24?) gal reeftank for quarantine with another AquaSun 150 W MH DE .
I quarantine my clams and anemones in this tank before put them in DT. If they get sick then they go into the bare 20 g hospital tank.
