Review on 🐠 AQQA Aquarium Electric Power Sponge Filter - 3W/5W Submersible Foam Filter for Saltwater and Freshwater Fish Tank by Kayla Walker

I like the product very much. Exactly what I was looking for. At first I was startled by the noise because I hooked it up to a monster air pump, but then I remembered I had a built in airflow adjustment knob. So I gave up a bit and BAM! Completely silent and flows beautifully! The suction cups seem to be of great quality. Both have tabs that you can easily remove if needed, but they seem to be holding up great. The sponges themselves rotate easily if you wish. I like that the drain hose can be rotated 360°. I placed it on the back of my 20G Long but still tilted the outlet so it flows the full length of the tank. Also a great idea! You will also receive two replacement sponges and a carrier. I'll probably never replace sponges, but if I do, it's great they dropped them. To be honest I think they would work great as a pre-filter on my Penguin cooktop!
