Review on 🐠 NEWKOSEA Double Sponge Aquarium Air Filter - Bio Sponge Filter for Betta Breeding, Shrimps, and Fish Fry Tanks by Marcel Snoddy

Used this product on my 10 gallon pool. The filter level is perfect. I like that it has an adjustable capacity so the filter can be placed where is most convenient in the aquarium. I also like that you only have to clean one sponge at a time. This is much more efficient than traditionally mounted rear cartridge filters. I will buy more of these in the future. You must purchase your own air pump and air duct for this filter to work. Otherwise, it's a great, inexpensive product.
