I have a salt water pool. I have been lucky so far, to have 2 summer's of relatively free maintenance. (My testing seems to come in within limits every time.)
The only chemical aside from the Salt, that I've been adding to the pool this year is BioGuard Pool Magnet (remedy).
I fill the pool a couple of inches once a week or two with water that has high iron content.
My question is, how can I determine the safety to humans using this product? Obviously the manufacturer will tell you its safe. Are there any other information sources for this kind of thing?
