Boxtech Aquarium Pneumatic Filter 3 in 1 Bio Sponge Filter for 10 - 100 Gallon Fish Tanks
Product Review (submitted on March 28, 2022):
Filter nano tank with just air pump. Yes plz. I didn't expect much due to the price, but I was pleasantly surprised. The side sections are perfect for adding media/polyfil for water polishing in bigger tanks and perfect for 10 gallon shrimp tank.
