MarineDepot.com Education Center - Aquarium Calculators
How much water is inside my tank?
Knowing your aquarium's water volume is extremely useful. You can use it to determine how much your water needs to circulate, which filtration equipment to buy, how much water to change, how much medicine or supplement to dose and even how much livestock can safely inhabit your tank.

How much sand will I need?
Whether you're planning a shallow sand bed for a fish-only tank or a deep sand bed for your mixed reef, our CaribSea-powered sand bed calculator helps ensure you buy the right amount of sand for your system. Just enter your aquarium's length, width and ideal sand bed depth to calculate how many pounds of sand you'll need.

How much will my electric bill be?
Our aquarium electrical calculator will give you a pretty good idea of how much you'll fork over for your monthly and yearly electricity bills. Just plug in the wattage of your equipment—lights, pumps, protein skimmers, reactors, etc. —and how many hours per day you intend to run each of them and voilà!

"As always my experience with Marine Depot was 'overall satisfaction.' If on the phone, by video or the write-in reviews on the product I am interested in, they are always helpful. When I am in doubt of what product will help me or where to find it, Marine Depot is usually the first and last place I go to."
