I asked several days/weeks ago, doing the same as you, but here's where I am
so far, 2 bags won't cover it, 3 might do the job... I'm also mixing half a
bag of 25lbs small pea gravel with it...


My 37 gallon tank is 24inches by 20ish inches.

It took 3 bags to get 2.5 - 3 inches.

I bought mine from BigAlsOnline.com. With shipping, it was $17.00 a
bag shipped directly to your door. A bit cheaper than the $25.00 to
$28.00 that local dealers sell it for (plus you have to pay tax).
