best filter bags
(Posted on 3/11/12)
Comments: I don't usually write these reviews but these are the best media bags I've found and I've used them exclusively for years. 2 reasons. First is the velcro closures. You don't have to mess with those little strings the others have. The velcro is strong and lasts for years. The other reason is that these have a double layer of mesh. The outer layer has wide openings (800 microns) so plenty of water flows through and they don't clog up quickly. The inner layer is a fine mesh (micron size not stated) so the filter media stays in. Still need to rinse your media before first use to get the dust particles out, though.
