I was clueless a few weeks ago and listened to the pool store. Found this forum and the sister web site, studdied it, and asked a few questions. I now have a pool with water like liquid glass. The installer came out a few days ago to fix a light and comented on the water. If I listened to the pool store I would be spending $40 on oxy-shock and $30 on regular shock not counting trichlor tabs each month. I spent $17.84 last month on chems. I spend 20 minutes a day and about a hour on the week ends keeping it up. The BBB system should be called the symplisity system is it so easy to keep up. When you get your pool up come on back and let the pors here who really know their stuff get you started. Dont let the pool store sell you a stuff you dont need.
