i need to know how many 20lb bags to buy, thanks

I would say about 1lb per gallon, or 5 bags of 20lbs.

E.X. my 29 gallon used about 25lbs of sand. But that's only because I didn't want too much.

Foster Smith has that gravel cheaper because it's shipped for free. Just FYI. Unless you don't like buying from them. They don't add a handling charge for gravel. I just ordered 80lbs total for my 55 and they shipped it free like everything else.

I bought my sand for $3-4(50lb bag) at lowes and its really good...
Some people have white play sand , but i did not see white play sand when i went to buy the sand...

Some people have their preferences on retailers. I didn't want to sound like I was plugging for a company.

I used 80 pounds in a 55 because I like to make mounds, valleys, inclines and such. I prefer that look with plants and driftwood.

If you wanted just flat gravel, you can do the 1pound per gallon rule of thumb.

The CaribSea brand is packed wet in the bags, it doesn't get rinsed. I used it on my 55 and just ordered 40lbs more for a 29 tank.

In a 90, I think five bags of that would give you the inch thick you want. If I was ordering, I'd get 7-8 bags for my style of tank and maybe have a bit left over.
