Substrate Calculator
i selected flourite and it seemed to be the closest to PFS.
i used about 30lbs in my 20H (12x24) and got about 3". to rinse it, i just poured in a 5gal bucket and stuck the bucket in the shower. i let it fill up with water, and let the water keep running off the top as i stuck my arm in and swirled all the sand around. after a few minutes i'd dump as much water as i could, then filled it back up and started over. i just kept doing that until the water ran clear.
with our tank, we also rested it on it's side, and sprayed the heck out of it with hot water (small enough tank for the shower). we also let it fill up and wiped with paper towels.
good luck!
