I recently installed a Hayward SWG and in the manual it states if the pool does NOT have new water, that I should add 1 quart of metal remover and 1 quart of a non copper based algaecide to ensure a quick troublefree transfer to the Aquarite system. What products do you recommend for this ?? Also I may have to drain/fill the pool a little to get the CYA down some. Thx
