I just wanted to start here by saying "Hi" and I'm really looking forward to learning from this awesome group. I have found myself constantly finding helpful information from this site through my troubleshooting web searches. I am attempting to do the BBB method even though I am a fairly new pool owner. Last season (my first) I did the typical pool store recommendations and had a really good first year. But, I did not take care of the pool properly before closing and now I'm fighting a green pool from the beginning this season. Lesson learned lol. It has gotten better (I think), started off with a swamp full of tadpoles and now closer to a blueish green like color.
