How much fluorite?

[Eric]

So my amazing spouse gave me cash for the new tank for Valentine's.  How romantic!

Anyone have a guess how many bags of fluorite for a 72 bowfront about 2-3"?  I live far from Ottawa, so it will be one trip to buy, and I can't picture the bags.  Four?  Five?

At least 5 bags... more like 6.  I have 5 in one of my 75's, and its a little too thin in the front....

One bag in my 10 gallon gave me about 3" of substrate... so 7?

I have 6 in my 75 (48X18) & would prefer another bag or 2 .

Thanks all - I will try 6 methinks.

Sorry to bud in here, Eric, but maybe this will help us both.

Where is the cheapest source for fluorite or an equivalent product?
