A few weeks ago we restarted a marine tank. It is 270 liters and we have 2
clowns and 2 damsels in the tank. We have came accross a nitrite and amonia
problem that we can not seem to get rid of. We have put some bio balls in
the tank along with some "Easylife" and that seemed to have helped with the
amonia but the Nitrite is still high. We even went as far as a complete
water change as a last resort.

Can anyone sugest what we can do as we are at our wits end.
