you know will make the water changing faster a drill pump lol I used it and its freakin great just turn the drill on hold the trigger and away you goooo lol
ive heard of people using filters to change water with. i can see why..... put intake in tank, turn on, suck water, put output tube down drain wahlah, for adding water from giant tub, reverse hoses lol. maybe ill get an extra fx5 to do that for me, then you just leave them hooked up until you are all full.
