Review on 🐠 XINYOU Corner Filter Aquarium Fish Tank Internal Air Driven Filter with Media XY-2008 for AquaCity by Wendy Turner

This was a cheap and great secondary filter if you already have one. I have an aquarium with mollies and two mollies have an insane bioburden. Here I have a normal filter from Aqueon and this one in the corner. Not particularly easy to clean - you really need a sharp fingernail or something to open the lid - but otherwise very easy and overall a great idea - this is a filter with 3 types of sponges (2 dark - one fine, one coarse, 1 light) plus ceramic spatula and pebbles on the bottom. You REALLY need to buy an air pump. Also, the white sponge will definitely get dirty. You should probably choose a different color for the top sponge :)
