Title: No! No! No!
Product review: Don't buy. If you have already ordered, cancel the order.This Carbon Insert is the reason why the excellent Zoo Med filter is selling on clearance.Basically, this insert is a bag of carbon which has been machined into smooth pellets. The smooth surfaces fail to allow for the absorption of organics, and it left my tank with a high ammonia content for weeks. It doesn't work.Go to the pet store, buy a nylon bag and over-the-counter activated carbon chips. The chips have rough porous surfaces which increase the absorption rate. This makes the Zoo Med filter run exceedingly well; transparent water and ammonia at zero.
