I figured on the calculator how much flourite to buy for a 90 gallon (said 90 lbs) so I ordered it and on the bag of flourite (l5 1/2 lbs) it says it will do 2" in a 10 gallon. Why the difference?? I hope I have enough- :?

So far the calculator has been pretty close so as long as you put in the proper tank dimensions it should be OK. You must have ordered 100lbs (5 - 20 lb Bags ?) so you should get the extra 10 lbs.over what it claims you need as a buffer.
Please let us know how you make out as the calculator is still fairly new.

Hi
It says I need 600+ punds of Eco Complete for my 55 gallon tank?
I may be wrong but that sounds like an also lot of pounds and money.

My tank dimesions are
20 DEPTH
48 length
13 WIDTH

Depth I did form top to bottom of tank
Length I did from West to East of tank (left to right)
and Width I did North to South of tank

Is this right

Well, according to the calculator, you would need 13 lbs. of Flourite to make a 2" deep bed in a ten gallon. A standard 10 gallon is 20x10 inches, whereas a standard 90 is 48x18 inches. So...200 square inches and 864 square inches. If you wanted 2" in your tank you'd need about 60 lbs. If you want 3 inches you need about 90 lbs like the calculator said. HTH

No, if you should have put 3 for the depth because you only want three inches of substrate. if you put 20 for depth it gave you the amount you would need to fill your whole tank to the top with eco-complete.

I know on the bag of flourite, it says 1 bag is good for 10gallons...and it's assuming a normal tank, not a hex, not a long.

I can tell you that I've already put 5.5 bags of flourite, plus 15lbs of pea gravel in my standard 75gallon (48"x18"x20") and I still don't have enough depth in all areas.

Eco-complete is the same way...teh bag weighs more, but it's packed with a lot of liquid...it's really the same weight as the florite.

So, really, you'd want 9 bags.

9 bags? I think that'd be way too much, 7 should be just fine. Her tank has the same footprint as yours.

I bought 6 bags and had to drive over an hour to get it so probably wont go back. Buck, flourite bags are 15 1/2 lbs each not twenty. Its a weird amount of weight I think too. Anyways, I have the 6 bags in and it is about 2" deep, is that going to be enough?? I can add gravel but I hate to after spending all the money (130.00) so I could do 100% flourite. :? Is 2" deep enough??

I did pick 3" deep on the calculator and it came up 90 lbs I needed and I have 93 and it is only about 2" at the most.... ops:

On my 77 with a 48" x 16" (approx) dimensions I used 7 bags of flourite.

The weight of a bag of Flourite is 7 kilograms (for us Canucks:-)
