Fiji Cube AIO Box All-in-One Kit 4th Gen - 40 Gallon Breeder

So I'm just going to explain why I'm only scoring 3 stars. And it is for lack of instructions, and what to do about the giant gaps on the sides. A video and some "side fill material" would give it 5 stars. I decided to glue mine to the side panal of my 40 breeder, making a complete circle of silicon so no water leaks into the center. For the sides, I'm going to use some corse filter media so fish don't enter and leave the voids for worms and copepods.

Good product 👌

item is a little to tall to fit under the lip of my 40 gallon breeder, had to do some modifications so there would be no gap behind unit!
