Thanks all. I currently have a 30 gl with like 30lbs lr and a 4" ls bed. The only bio load on it is 1 sebae clown and two anemones, also 6 snails,2 camel shrimp, and an emerald crab. I currently run it on average of an hour at night before lights out. Does this sound good to you all? Should I run it longer, or more often? All input is appreciated. Thanks.
