Just finished re-washing 60lbs of black diamond blasting media for my new 40gal tank.... Was quite the chore. Each bucket of sand was washed and rewashed about 4-5 times before the rinse was ran mostly clear. The tank was just topped off with tap water and I've got two old filters running with some home-made filter pads to polish the remaining cloudiness out of the water. If all goes like it going right now with the water getting much clearer sooner than expected, I'm going to do a 70% change this afternoon and move my plants from the old tank to the new one, replace the water with RO and move the old filter system which is cycled to the new tank along with a brand new filter and hopefully things will take off from there.

That sounds great! What fish are you gonna put in?
