Do you know what type of gravel it is? It's difficult to say but you could work it out based on the density of the gravel and the area you wish to fill.

Its just going to be natural pea gravel probs 2 or 3mm grade

1) figure cubic inches of gravel needed... length times width of aquarium times desired height (in inches)

2) measure cubic inches of one bag of gravel..approximate lengths) times width times height (in inches) of bag. Divide result of step one by result of step two to figure number of bags needed.
