I know I should know better but I figured I would ask. Last season I had a friend that was battling algae and his local pool store told him to add the Proteam version of the Borax. After adding about half of what was needed for his pool size I told him to add the 20 mule team borax. He went and asked his local pool guy and he didn't know what to say at first but said he would talk to someone that had more knowledge about chemistry. Well the pool store comes back with you should never put that stuff in your pool is has arsenic in it and the level of arsenic will build up overtime as you continue to add it.
Is there any truth to this? I don't remember reading anything like this on the site.
