Review on Premium RO6G BCP Pre-Filter Foam Sponge 🐠 Roll – Essential for Crystal Clear Aquarium Fish Tanks by Joyce Cain

These are great pre-filters that I use in my 20 gallon goldfish tank. Before I received it, two things happened. At first the algae-eating snails were interested in the filter inlet and were already dead when I found them. Second, when the goldfish ate or uprooted the plants, the plants would be sucked into the intake pipe and slowly rot. It was impossible to clean without an old toothbrush. These filters solve all problems. The snails cleaned the filters and survived well. Plants just stay tuned. The flow of water into the filter remains good, but it's like night time, it "clogs" what you know of the reduced flow and you see the filter sucking in. I just swap it out for another at 8-ok and clean the old one by running it in water and squeezing out all the dirt before using it again. This way I reuse two and haven't had to throw them away yet. Highly recommended!
