I have a 55 gallon tank. This is my first tank. No corals or lights, just some live rock and fish. It's been running for about 2 months now and all of my readings (ph, no2 etc) have been normal. I use an Ehiem 2227 pro filter with a surge, it's been running 24/7. A great filter but a little noisy at night (sounds like the ocean is in my living room). According to the specs it moves 192 gph. Should this filter be run all day and night or can I start turning it off for a few hours?
Thanks for your help.
