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

Excellent filter. Really cleans and polishes the water. I have three FLUVAL FX6 in a 200g tank and they do their job well but! The water wasn't crystal clear. This filter in the Marineland Magnum really cleans the water, I really like that. With this filter everything is now crystal clear. Follow the cleaning instructions carefully. Bleach and water required, soak for 24 hours, remove and rinse well. That works great. However, do not leave the filter in the water and do not bleach it again. This will melt the blue rubber at the top and bottom. I forgot it and soaked it for 4 days and it melted the rubber and I had to throw it away. Follow the instructions and everything will be fine.
