Review on 🐠 Powkoo Mini Sponge Filter: Small but Mighty Air Filtration for 1-3 Gallon Fish Tanks by Jacki Beauchene

Airflow issues from the start. The main body consists of two plastic parts that are not sealed. Air comes out the back and I had to fix it twice so it barely works anymore. I won't be buying another one, I'll stick with the standard sponge filter. It only got two stars because it's small and very weak, which I obviously need. And while it works. Edited July 2019. I got fed up with this filter and replaced it with a standard sponge filter. I think I was ready for repair #4 and still couldn't stop the air leak. Then he whistled through the hole in his back. Obviously, this is a violation of the terms of the deal. Maybe you're luckier than me.
