GTR73 Posted January 25, 2006 Share Posted January 25, 2006 Excuse my ignorance as I've always used internal & external canisters, but how do internal drop filters work? I've heard they're the tool of choice because of their huge capacity and low cost to run. Anyone have a diagram? Do they make much noise? Apparently an airstone is used - do you necessarily need to use a pump? Can you run it the opposite way, with the intake at the bottom and using a pump? I'm sure this topic has been covered before but it's been a bit hard to glean info from searching the forum. Thanks Link to comment Share on other sites More sharing options...

GTR73 Posted January 25, 2006 Author Share Posted January 25, 2006 Ah heck! I didn't think to type in air driven filter on the search engine. Explains what I wanted to know perfectly. Thanks heaps Ash. Link to comment Share on other sites More sharing options...
