Need to know how many gals. my tank is?

Any Mathmeticians out there? It measures 24"x24"x24" with an eheim 2217 full of water (maybe 2 gals with tubing) Thanks (need to know so I can dose correctly)

(24inches x 24 inches x 24 inches)/231 = 59.84 gallons tank volume

Hope this helps!

2.5" substrate in YOUR tank will decrease your water volume by about 4 gallons, 3", about 5 gallons.

Yeah- probably 1 1/2-2" of flourite- didn't think of that, also drift wood (big one) so maybe figure like 60+2 for filter,tubing. Minus substrate minus plants minus fish= maybe 56 1/2 gals . close enough?

For fertilizing, 50 gallons and 60 gallons are the same. You don't need to be very accurate with fertilizing.

btodd,

Every inch of height in your tank equals 2.49 gallons of water. So 2.5 inches in height is equal to 6.23 gallons, and 3 inches of height is actually equal to 7.47 gallons. You can play Archimedes and fill your tank high enough to cover your driftwood and mark the height of the waterline. Place the driftwood in the tank and mark the new waterline. The distance between the two marks will allow you to calculate the actual amount of water the wood displaces.

Go on, play scientist and let us know how you do!

You could also stand on a bathroom scale, then pick up the tank with substrate, driftwood, etc. in it and reweigh yourself. The difference is the "empty" weight. Now fill it with water.........

I think btodd needed to know the amount of water volume the driftwood occupies versus the weight. Not the same.
