Review on 🐠 Aquapapa Pack of 2 Bio Sponge Filter for Betta Fry Aquarium Fish Tank Up to 55 Gallons Each - Double Sponges by Erica Noble

No complaints at all! I can't believe you get 2 full filters for what often costs 1 sponge pre-filter. They work great. I actually have a 10 gallon one with shrimp, guppies and angelfish and a fifty five gallon one with angelfish, acera gourami, char and some zebrafish. This is still ongoing. Air pumps are tailored for each tank - for example a small, cheap Wal-Mart pump on the 10th and a decent dual outlet on the 55th that uses only one outlet to operate the filter. Ultimately, for tanks over 10-20 gallons they will probably be the best secondary filter, but using one on my 55 while I'm working on my canister filter is a proof of concept. They appear to cycle very quickly and respond adequately to biological stress demands. Breeding tanks, shrimp tanks, small aquariums or fighting fish tanks are ideal. They're also extremely simple, allowing you another point of ventilation and circulation. I place pickups in places where the water doesn't always move well (behind large decorations, in corners) and they help keep everything clean. The shrimp love to skin them, my botia loves to hide under/behind them. The spout is height adjustable. It fits my 10 and the rosette gets quite big, only about 18 inches. Everyone should have a worker. If you have me, you have roasts, for some reason you need another tank, like *now* that's great. Pour water. Warm up. Add an airline and a sponge and she's ready to protect your fish.
