Wow! You guys paid $10 per bag! The bags at my local pool store are only $3! You should in a 55 and 125 use about 200 pounds. I would get 10 bags lol. Just to be sure you have extra sand in the future I would get extra sand. Also if anything goes wrong you can have "backup" sand. Good luck! I currently have 200 pounds of play/pool filter sand sitting in my basement. I get extra every time so that I can have backup and replacement sand. I would for you get like 6 bags. You should be fine with that.
