ideally a wrasse or some other fw predator, id offer my mother in law, but im not sure shell fit in your tank
sorry, couldnt resist. i tried the mel. wrasse i thought it worked well i also supplemented with fwe and siphoned the dead ones of the sand bed. i ran carbon as well
Safest way is the melanarus wrasse. Flat worm exit works well too but you need to be careful you don't toxify your tank. Even when you siphon out the dead ones you can see,you are at risk because of the dead ones you can't see in your live rock.
