I'm running a eheim 2217 filter on my 46 gallon bow front tank. I switched from a whisper 30-60 hob
and my tank water was crystal clear. Now I notice more particles floating and missing the input of the eheim mostly floating up top. I've tried micron pads and polyfill but it looks as if the particles are just more floating by the input. unless someone has a different suggestion, I was planning on getting a aquaclear power head with the filter attachment to use as a mechanical filter. And help with the upper level particles. My question is what size should I get for this? Do I need something that will filter 46 gallons a few times an hour since I have the eheim? I already have a lot of flow so don't want to much current. Tank is set up to cater to my discus. I believe my tank is tall as well because the eheim input sits a few inches above the substrate don't know if that matters.
