Seapool? Nope - C-Pool!

[Spensar]

Read this in another non-pool forum. Person posted about more efficient pool pumps, and I posted links to pool solutions, then this post showed up. Never heard of Seapool, and am wondering about the sanitation of what was posted there?

my dad uses a chemical in his pool called "SEAPOOL". it is a copper-sulfate compound that replaces the use of chlorine in the pool with an exception to one puck a week in the skimmer. the advantage to using SEAPOOL is that it only requires the pump and filter to be run twice a day for 3 hours at a time. so he has it set up on a automatic timmer and as you can guess saved 75% of his electricity bill for the pool. *There is no conversion kit that is required to use this chemical, unlike a saltwater pool.*
