It’s pretty great, and requires minimal maintenance. It’s a wet/dry filtration system, with three chambers build into the back. The water flows into one chamber through very small slits in the back, then over flows into the filtration chamber with a filter pad (I’ve just been using the large pads that you can cut to fit rather than the fancy one designed for the tank) and three bags of bio media, and then flows into the return chamber with the pump. It’s kind of like a built in sump.

It a 30 gallon Oceanic Biocube the one I have is an older model.
That's really really expensive. Biocubes are less than that. Even their 29 is less. https://www.amazon.com/Coralife-15607-Biocube-Size-29/dp/B007UQA7CS
Thanks for the reply! I'm really thinking I'm going to make the purchase.
I'm really not sure. I know this is the tank.
