need advise from all reefer here
As my tank is a 4ft reef tank, total volume is about 70 gallon, about 1 year and 3month old.
Over the year, i added into the tank,
1 salifin tang
1 yellow tang
1 purple tang
1 yellow eye kola
and finally a Power blue tang.
I feel that my tank system cannot keep up with the bioload anymore But i really dont know many many and which should i keep or sell off.
Can give me some advise pls.....
