Last week i had a problem with my marineland c-220 canister filter w/ no bypass system, so i called the company and the rep had me look things over ,take apart and reassemble the whole cap WOW i now know my filter. He determined that i would need a replacement valve block so they sent me an entier new filter, I had used a bio-wheel 200, which i filled w/ bioballs and foam from my old filter to preserve the biological part. I noticed i had lost the ball bearings to the bio wheel(my fault) so they're sending me some of them nowtoo. I got my new filter going today and theres a big difference in the water quality, i would never go with another type again.
Thank you marineland customer support guy!
