    I want to get black sand for my 29 but dont know how much to get. I read some artucles but none of them helped. An exact answer would be much appreciated.

    I have a 34 gallon with s foot print similar to a 29. I wanted sand, but didn’t want the risk if anaerobic bacteria that can occur with >2 inch depth. I bought a 59# bag of BDBS & it worked great.

    Best that I remember, I used about 35 pounds of BDBS in my 20 long (same footprint as a 29).

    Just buy a bag that you would estimate to be enough. Then, shoot for a depth of 1.5-2” substrate depth. I don’t have experience with any kinds of blac( sands, so it may be different than other substrates.

    29x1.5=43.5 pounds

    If your bag of black sand you linked weighs 20 pounds, then you can buy 2 bags and be totally fine.

    It's really more about preference. You can have less substrate.

    Just get some Malaysia trumpet snails to take care of anaerobic gas'. They burrow through the substrate keeping it oxygenated.

    So is 1.5 inches of sand hetter than 2? How many pounds of sand would it take for it to be 1.5 or 2 inches?
