So happy to find TFP. Help pls. 1st year on my own (husband passed). 22K gal IG vinyl pool, Hayward sand, no heater, well water. Opened 2-3 weeks ago (mesh cover): removed debris, brushed & shocked. Water cleared overnight though cloudy. I did not stay on top of things so algae making a come back, light greenish color now. Last night: brushed, shocked, used poly algaecide. Test results (pool store) a/o this morning:
Read Sparkling Oasis etc. and fumbled around w/pool calculator but not confident on what to do. Want to learn BBB method (tired of expensive pool store products).
