im not sure how much I’m expect to use. Yet here is the tank I have actually if you need to know.https://www.petsuppliesplus.com/shopping/Aqueon-Aquarium-Long-Tank/8463Got this from a arbitrarily site however it has the details if you need to know.30.3 x 12.5 x 12.8 inches
*

About 36 lbs for 2 inches thick or 18 lbs for one inch. Ns assumed 30.3 was length of tank and also 12.3 to be the width. Still be around the very same if the width was 12.5, but I suspect 12.5 to be the height.

If you got a 50 lb, bag, you would have actually gravel for various other tanks.
Before deciding ~ above gravel, what fish are you intending for this tank? Some perfect to this size tank will require sand, and also sand is typically a far better substrate.
If you go by the two inch dominance I based mine calculations on the bottom area of his tank floor. If raingamma just wants an customs depth coverage end area of tank floor he would only require 18 lbs.

OK, that"s not an issue. I would certainly suggest about 1.5 inch depth once spread flat, climate you can aquascape it to have it slightly more in ago and less in front.
I just found this website....http://www.howmanyfish.com/how-much-gravel.htmAnd I provided the measurements from her tank, Andy I come up with....36 pounds of gravel. 42 pounds of dry sand. And also 54 pounds of wet sand. If you gained play sand, (they come in 50lb bags, at Lowe’s for just $4, a killer deal) not only does it look great, yet it is also easier to “keep” in a tank. JMO.

I am unconvinced of your calculations, or rather, I"d be interested in why they think one requirements so much substrate. Putting 42 pounds of dried sand in a 20g substrate is around dual what girlfriend need. But it is quite to have actually extra as you say, good point.
