Not sure how I got 100 before, I only did the test once, so maybe I did something wrong. So, a target of 40...

    Thank you all for the great information! This all gives me some really good direction for more learning. I had to leave town for the weekend, but I'll get started when I get back. How to drain and where to put the water is not a problem. I'll post back here when done.

    Need some advice on partial drain for algae/CYA problem

    Hello great people of TFP! I've been lurking around here since I put up my pool in August of last year, but I've been lazy and using pucks and cal-hypo. After opening 4-6 weeks ago, the water was clear and I just needed to shock and go on with using the pucks and cal-hypo. A few days ago, the...
