I am very pleased with Bio Bags. They keep my 55gallon tank crystal clear. I also like the auto shipment....That is really a plus.
I recommend Bio Bags to anyone with a fish tank, for healthy fish and an clear tank...

These are good filters, and easy to change. I hope the pumps which support these continue to be manufactured

Product works well for its intended use. If you want a middle of the road filter for a very reasonable price, the Bio-Bag filters work well. It does what it is made and designed for and is very easy to change.
