Greetings fellow aquarists, I've been given an Eheim 2215 and I'm wondering if it would be beneficial or detrimental adding it to my 65 gallon salt water tank. I added it about 3 months ago and levels are all still good. Nitrite (0.2ppm), nitrate (10ppm), salinity (31ppt) with zero ammonia at 78.6 degrees F. The only difference is water clarity has improved a bit. Also wondering if ceramic filter media in the 2215 is appropriate or if I should fill the canister with bio balls. Thanks for any insights. Oh, 2 clowns, 1 cardinal, 1 damsel and 6 snails. The one clown is isolated until he grows a bit and doesn't get bullied, I let him out when I can keep an eye on him.
