Filtermax 3 On My Fx4’s

I just put the filtermax 3’s on both my fx4’s in my 125. Is there anything I need to know about these pre filters? I’ve never used prefilters before but was told to run them bc the fx series and sand don’t seem to mix. I really like how they look minus seeing the debris on the sponge. I’m about anal and will want to clean them everyday. But I know that wouldn’t be good for BB on them. Anyways just wanted to hear some opinions or any tips on these prefilters

The only pre filter I have is poly fil. I just put a generous amount on the top and use that to catch the garbage.

I have sand in my 90g that has the FX4 but I’ve not had any problems with them together.

awesome I use polyfil aswell inside my filters. I just got the atI filtermax 3 to cover my intakes as extra precaution. But thanks for the input

I'm running an FX4 with PFS and have had no issues. The intake is about 6 inches off the bottom of a 46 Bowfront. No pre-filter.
