Review on Aquapapa 4X Bio Sponge Filter: Ideal Betta Fry Aquarium Solution for Tanks up to 15 Gal by Maria Botello

Order for the second time. I love bettas and they live in nano aquariums all over my house (5-6 gallons). The closer the outlet is to the surface, the more electricity they generate. This short block can be placed near the bottom and the upward airflow from the deeper outlet cancels out most of the horizontal water flow. These devices ensure very good filtration of the Betta tank, even with one or two housemates. If you know someone who owns a 3D printer, you can convert the outlet into a threaded device that allows for water threads and a charcoal filter and turns that thing into a beast. Filter. I have a friend like this and I am thankful that my water is crystal clear and smells like a spring no matter what. Every nano tank in my house still needs regular maintenance. But my water is so clear and odorless that many guests worry that I overdo it with regular cleanings.
