How Much ABG for a 120 Gallon Tank?

[Strider18]

Hey all,

I have a 120 gallon aquarium that I have been trying to set up for dart frogs and am wondering how much ABG I need to get a 2-3 inch layer? The measurements are 72 in x 18 in x 24 in (LxWxH).

Thanks!

Well for 3" deep you have 3888 square inches if I did the math right so if they are selling it by dry quarts, then that will be about 57 quarts. But actual results may vary as you might compact it more than they did when they came up with their figure.

If they sell it by weight, you'll just have to eyeball the size of the package unless they give you a coverage or some conversion method.

Wow thanks! That's about $100 in ABG though, not cheap. Good thing I'm not planning on getting frogs for awhile haha. Guess my little brother is getting a good present when I go away for college

I don't have a frog that requires the use of ABG, so you might try to get some info from those that do. It may be that you don't need to cover all the bottom with ABG. The rest could be other features that are appropriate for your creature, or just something that adds interest.

I'd also try to get an idea how often you are going to have to replace the ABG. I've seen a few posts that seem to indicate that it might need replacement several times a year. So if the 100 bucks is pricey, it will only get worse. <<grin>>
