ok so this is the first time i have ever put sand in my fish tank, i am starting out by putting it in a 10 gallon, i have rinsed the sand multiple times, tried pouring the water in slowly, and waiting... and the water is still very murky, is there anything that i am doing wrong or is there some special way to get the water in the tank, right now i am siphoning it in with a small bubbler tube, it is KIND OF working, or am i supposed to put the water in first then dump the sand in? any help would be great!
