Used for 3 weeks according to directions. Still have the black algae that I had when started.The order doubled during checkout. Customer service is provided by people in another country. The CSR only told me it was my fault and to send back the extra products at my expense. Shipping confirmed they received the product back a week ago. No refund yet.I do not recommend buying here. The products are no better than your local pool store. The customer service is nonexistent.

Very bad. Do not buy anything from Doheny. They initially promised delivery within a relatively short time and after I was placed the order they kept pushing delivery back a couple more days each time. Kept changing and moving it back only to NEVER receive it! I left them a message to at least refund me and have heard Nothing! I would give them 0 stars if I could

I let black algae get a foothold in the pool...bad move. I hit it hard with Doheny's and a steel brush and then dropped back to the maintenance level - killed a bunch of it at first. Since then it hasn't gotten any worse, but it's still there despite continued use of both the algaecide and the brush. I'll stick with it for maintenance, gotta try something else to remove the rest of the black stain.

I work at an RV park and buy products for our swimming pool. I use the Doheny products and I’m very impressed by them. I used to use a few other brands but once I latched onto this one and I haven’t turned back o. They are top notch.

This product killed the algae that was on 10%-15% of my inground pool floor and walls. I used double the amount recommended. The algae was gone in about 10 days. Be aware this product has a relatively high copper content. I have a slight stain on about 5% of my pool floor. I will need to remove the copper before applying a stain remover.

This product works well for removing algae and making the water clear.
