azarett Posted April 14, 2018 Report Share Posted April 14, 2018 New tub owner ( So I stink at reading chemical tests ?) But I'm trying. About 2 weeks ago, the water got cloudy. Hard to be sure due to color of tub, but It looked slightly green, so I thought 'algicide' So I did. The algicide only had dosing for 10,000 pools. ( although it said pool & spa on the package) I thought it worked because the next day, water seemed clear, and the top had a lot of green matter on the surface. I assumed the green was dead alge . The water has been clear since then, but the angicide said to add small amount each week. Every time I add, I get green foam when the pump cycles. It the green being caused by too much algicide ? or is it just green because I have not killed off ALL the alge ? The pics is from this morning Thanks.
