Hi. I'm Torre(cootiequeen) and have recently inherited a home made lap pool. It's about 30' x 6' and 3' deep. I'm told may be less than 5k gal. I'm only able to be here on weekends and sometimes skip a weekend. Most of the time I've been able to keep the water in balance but occasionally I miss a treatment. Then pond scum smell! I put some acid in it and the smell was gone within an hour. I threw half a pkg of shock in before I left for the week. Got test strips. It seems to be doing ok. I think I need to put acid in the night we arrive and chlorine before we leave. And a lot of chlorine if I'm going to be gone more than a week. Any thoughts? I read the water should be circulated daily but I haven't mastered the timer yet and just used it manually when I'm there.
