i have no idea what im going to do with them all .. going to clean them all up and go thru the boxes and boxes of crap clean it up and see just what i have ... then i guess i will go from there .. sell some of it .. use some of it .. throw a lot of it away ... but for the price i got the 2 75's and 50 breeder .. the rest was free in my eyes ..
I've had experience with cleaning used filters... especially AC filters..
Use an old toothbrush.... as for tanks.. if ur not using it for fish immediately.. def use 409 to clean out any of the stains.. and use those taping knife from home deport... that will do the trick..
