one 50 pound bag was perfect for my 75 gallon tank. just buy one 50 pound bag and put how ever much sand you want in it. 3/4 the bag? how ever much you want
So I didn't think I would have time to make the change till next weekend. I was just too anxious to do it, so I MADE TIME! Lol
I just finished putting all the sand in and it's still not settled. It's pretty cloudy yet. Anybody know how long it takes to settle?
