I have a 55 gallon tank with a aquedon model 55. Presently, a lot of plants. Not crazy about the aquedon but would alos get the Eheim 2180. The ammonia is close to 0. I was wondering that the biomedia in a 2180 would interfere with the plants? I can lower the rate of gph on the 2180 and with the media in there and two hoses the rate should be ok.Just wan the water crystal clear and great filteration. Thoughts?
