🔍 6-Pack of Top Fin Retreat RF-L Filter Cartridges Review

Perfect for my 5 gallon tank but the price was high. I bought it because I can't find it anywhere else. Pat Smart was sold out.

Item as described although packaging arrived damaged. Although the filters remained intact. Although most likely because of the delivery service. Maybe next time a box instead of a padded mailing envelope? Many Thanks.

Filter elements are easy to clean but due to limited surface area they only last a decent amount of time (over a week) at very low fill densities. Even with a moderate population density, the filter must be cleaned every other day. Not recommended for anything larger than 5 gallons, and much less if using a moderate population density.
