10 gallon tank w/ an Eclipse 1 filter system. This is a power multi filter, flourescent light, hood, all in 1. The cheapest retail I have ever seen on them is $59.99. It was used for less than 1 year. $5.00 for the tank & $25.00 for the filter system. I can throw in a heater that was bought in for it too that already has the fitting on the hood cut out. 10 gallon w/ undergravel filter, full incandescent hood, and pump. $10.00. 10 gallon w/ undergravel filter, indandescent light strip, NO hood. $5.00 I have about 3-5 of large whisper and rena/optima filters that I will match up with a tank. They all function, although the may not be creating their highest output of air because of old or cracked diaphragms. These are part taht you can pick up for a dollar. All the pumps have extensive amounts of house and air release fittings that will come with them.
