Leslie's Copper Algaecide - Swimming Pool Algae Preventative - 1 Quart

I used this to clear my pool water, it was so green from alge and I tried every thing. After I got my water clear I bought a solar copper ionizer and I only use one 3 inch tablet a week. It has cut down on my chlorine use. I highly recommend this. Wish I took pictures.

If you use a copper based algeacide don't use cal-hypo powder shock. I added leslie's power powder shock to the pool and it stained the plaster a blue-black color. Has never completely faded and I will have to resurface pool. Neither product has a warning about this but after a little online research I found this is a common reaction.
