Does filter foam pad lose effectiveness over time?

I have a 2 fluval c4 h.o.b. filters on my 55g and have kept the same poly foam pads in there for 8 months rinsing it tank water as needed. I've noticed this week that my water is clear but doesn't seem to be as clear as usual. Seems I can see more water particles floating in water. Is it time to maybe replace those pads? The pads aren't falling apart but do appear to be worn down.

Well, if they are getting thinner then yes, they are deteriorating. Also, if they don't hold their shape and bend as the water flows though it could create a gap on the edges that water passes through without going through the pad itself.

If possible put a new one in it with the old for a couple weeks to seed it with bacteria if you do decide to replace the old.

So after I replace one of the 2 pads wait a couple of weeks to replace the other? I do believe they have lost their shape by my undoing. Instead of just swooshing them through tank water I've been ringing them in tank water ,beating them up. Thanks alot for your help.

What else in your filters? Is it just the poly pad? If so I wouldn't change them both at the same time. Also if you have room you could run the old and new pad together for a couple of weeks then throw the old away.

The Fluval 'C' series is like a compartmentalized AquaClear - in addition to foam, it has chemical and bio-media with a unique wet/dry feature. I'd change the pad and determine the effect on the water.

Father Knows Best but Abbey knows everything! I once knew everything, then I asked one question.
