Review on 🐠 AQUANEAT Pack of 4 Double Bio Sponge Filters for Fry, Betta, Shrimp, Nano Aquarium Fish Tank – Enhanced SEO by Chris Cranor

Photo shows 2 suction cups on the back of each vertical tube - without these it's all on the surface and totally useless. ALSO very false advertising. Well, if they include suction cups: the tube extends almost twice as long - which is great, and the sponges are probably 30 or 40 PPI, they clog up quickly if you have a dirty tank, but you definitely won't get stuck. Overall if I got suction cups for all 4 filters I would give 4 stars as now I have to buy suction cups to even use them. Dissatisfied.
