Thank you everyone in advance for all of the input!
Bought a pool (that came with a house) 5 months ago. Previous owner only ran the pump 3 times a week and did not know much about how to take care of it (cloudy, algae problems, calcium scaling, etc.). After reading through this site and learning a TON, I've got my pool looking good, and hopefully balanced too!
My problem right now is certain recurring problem algae areas. Or actually, I just would like to find out what is normal. The same areas that had green algae stains on the plaster 5 months ago, and took a couple of months to go away (after balancing the pool when I moved in), are coming back now about once or twice a week. I just hit it with the brush and it goes away immediately. Is this normal? I noticed that the algae didn't appear during the colder winter months, so is this completely normal, now that the water is consistently over 70 degrees?
Thanks again and below are my latest test stats:
