Review on 💧 Marineland PA0140 Micron Cartridge: Optimal Filtration for Magnum Canister Filters - 1-Pack by Denese Fothergill

I bought two separate Marineland polishers and they worked 100% perfect with the filter pad that came with them. However, I bought this replacement filter a day and two after my polisher completely stopped working. It started making a ticking noise and the water didn't move. The polisher burned through completely. I replaced it thinking it was a canister and not a filter pad but just this week I replaced the filter in my second polisher with this filter I just bought and it did exactly the same thing as my old one. He broke my polisher. These inserts are designed for this type of polisher but for some reason I keep having problems with them and they keep breaking my polishers canisters. Totally crazy! Stay away from them and head straight to Petco to buy them instead.
