I check the bottom of the basket everytime I do a PWC
, just to remove excess junk. The sponge should collect a lot of gunk so there may be something diverting the flow. Carbon is fine although I don't run any, I like to use poly-fil for final, fine screening (where the carbon goes). Do you use any bio media? They look like little cylinders and it's where large colonies of bacteria will grow to use up ammo and no2
(nitrItes), shold be on top of the carbon and are an important step in the filtering process.
Here's my suggestion, pull the filter unit off and clean the case, tubes and basket in hot water (no soap of course). You'll want to pull the motor and clean the impeller and use a Q-tip to swab out the chamber where the impeller lives. Anytime you clean your sponge or bio media, use water taken from the tank because tap water will kill the bacteria. IMO
carbon packs are good at making the water clear (removing meds), but if left in too long can actually do the opposite and cause problems by leeching chems back into the tank.
The AC50 is a great filter and it's the one I recommend most everytime, so I hope you get your problem solved.
