Review on Fluval Foam Filter Block Replacement: Filter Media for 404, 405, 406, and 407 Aquarium Filters by Kayla Guzman

This Fluval BioFoam lasts a long time; Some of my Fluval foams are almost 2 years old and still work great. They are great for keeping a colony of beneficial bacteria. Simply rinse with dechlorinated water every two months. .This foam fits in a canister. Fluval 406 External Filter This unit keeps 6 large fish healthy with no ammonia or nitrites. -Pack 1st Fluval Biomax Biorings 500g/17.63oz 2nd and 3rd Matrix 2L/67.6oz. For truly clean water, also use the Aqueon 06079 QuietFlow 55/75 Power Filter, 400 gph hob. I place pieces of 110" x 110" Morning Glory Queen/King Low Loft lashes (bought from Walmart, it's a lot cheaper) in the aqueon and replace the lash when it gets dirty, at least once a week. This is cheaper than buying replacement Aqueon filters.
