Review on 🐠 Huijukon Double Bio Sponge Filter Foam for Betta Fry Shrimp Breeder Fish Tank: Efficient Aquarium Air Filtration Solution by Ashley Nelson

No installation instructions right out of the box. From the little damn picture I can get a pretty good idea of how this should be set up, but unfortunately even that didn't work because there's no way to have the right size pipe for the inlet valve or even the little blue element to prevent water flows in the wrong direction when power is removed. The reason I bought this set was so I didn't have to play any guessing games about what size hoses and manure would fit these filters and pumps. Besides, it didn't even come when it should have come. Arrived a day late. I even regret getting it!
