Algaecide Next year?

[RebelBob]

I have paid to have my pool closed in September for 4 years now, and I have never had any algae when it is opened in May. I plan to close myself next year so I just made a point to now look at the empty bottles they leave in my skimmers to see what they have been adding every year. Turns out it is Allchlor Stain and scale remover, and Algaecide 90.

How bad is this, and what should I plan to use next fall....polyquant?

Do you have the exact name they used, hopefully it is not like the one below because they use 11.8% Copper Sulfate Pentahydrate; 3% Copper as elemental
