hey guys, I was wondering if you could help me out on some questions I have about undergravel filters. This will be used in a 10 gallon tank BTW. OK, I was wondering how these things are setup, i bought one along time ago for my 29 gallon from wal mart and never could figure it out, no one at walmart knew what i needed or how they worked back then. SO anyways, since these are relativly cheap and i like to waste money on useless things i don't need i want one lol. Can you tell me everything that is needed, from air hoses, connectors, cartridges, filter itself, etc. and how to hook it up. I own a small air pump thats running a bubble stone and tube but i'm going to buy a dual outlet one in the next day or so for added power. What i don't understand is this, you have a filter plate under the gravel with one or two plastic tubes coming up to the top of the water, on top of the tubes is a charcoal cartridge, an air pump is conencted to that, so how do these work then, if thats how its hooked up wouldn't that force air down the tubes and up through the gravel? If so, then what would be the purpose of the charcoal packs at the top? Any help is greatly appreciated
