Hi everyone,
I've been having some trouble with ORP levels. No fish are in the tank, just corals, a few snails, and a collector urchin. The tank is about 200litrs and I used to run it as an open system until 4 months ago when my live feed pump died and it has been a closed system since then. Orp levels were around 500 and 400. It has gone down to 70/60 but it spikes up to 300s and goes back to 70s again. Can someone give me hand?
