Sparkyrad5150 Posted December 21, 2023 Share Posted December 21, 2023 I bought a Fluval FX2 a month or so ago and used the media that came with it. I’m using it in a 75 gallon community tank with about 10-12 fish in it. I want to have the cleanest and clearest tank possible without messing up the good bacteria. Fluval offers so many options in media for the FX2 and have no idea what combination would work the best. I’ve included pictures of what media is available. Any insight or suggestions would be greatly appreciated! Link to comment Share on other sites More sharing options...

I don't use carbon or anything to help remove Ammonia, Nitrite, or Nitrate so the last eight wouldn't be a choice for me. Link to comment Share on other sites More sharing options...

In general terms the way you set up any filter is going to be: Mechanical --> Biological --> Chemical filtration Mechanical filter is your prefilter and sponge Biological is your biorings Chemical would be optional and would be things like seachem purigen, carbon pads, phosphate pads, or granulated carbon. The next step is to figure out flow. this determines *where* you place the media. Quote How does water flow through an FX series canister? The water first moves to the bottom of the canister, and then rises to the top through the foam pads. It then passes back to the bottom of the canister through the media trays in the middle, before finally being returned to the aquarium. Meaning, the flow is through the outside of the trays first (white foam only) from bottom to the top. Then it goes from top to bottom through the center portion. Essentially, by default everything looks good with the exception of the middle section of the bottom tray. 1 Link to comment Share on other sites More sharing options...
