I have 3 tanks now; a 10, 20L and 55 and I'm spending too much time cleaning filters and changing water. I would like to get an outside filter (think they are called 'wet n dry vacs?) but I can't for the life of me find the kind I used back the 70s in my shop and LOVED them. It has a glass bottom and you put some kind of white powder in it before you started it up. I've been beating my head against the wall and STILL can't think of the name.
HELP!
