I've also switched to having the lower basket (of three) filled with filter floss (polyester batting). Is the filter clogging?
If it is,
A) how are the particulates bypassing the filter and returning to the tank?
B) would returning to Eheim MechPro improve matters? I don't see how. I hear some folk don't use floss inside of filters, just fine sponge...
Help!
The filter circulates the water adequately, pushing it back toward the intake. It looks like particulates aren’t being held in the canister now.
Or is it the wood? Or is it (recent) lack of vacuuming? So many variables.
I’ll try putting the Eheim MechPro back in tonight with a pad on top. #NearlyBald
I bought from Amazon, Fluval make ones specific for the FX4 although cheap Chinese variants are also available.Thanks. Do you have a link to a supplier?
They’re all blue.Sorry, are these the white/blue or white/pink ones?
