 Gas in my sand!
I've got about two inches of sand in my tank and there is always gas bubbles building up. What type of gas is this and is it harmful? I put a diamond goby in a couple of months ago and it only lasted a month. His bottom jaw actually rotted away and you could see the bone going across. Was this caused by the gas? I do stir it occassionally to free the gas. Sould I siphon some out and reduce its depth? I do have lots of snails and one sand siffting star, don't know why so much gas.
