Another algae question

Also wanted to add: re: sticky water My first thought was maybe salt, but our Pool Pilot says the salt level is 3600 ppm and the HTH salt test strips pretty much agree (3680)....but not sure of the accuracy of either. It's not horrible sticky, but just as it dries, my fingers feel sticky for a bit. Then it goes away. Maybe it's been so long since the pool has been open that I forgot what the saltwater feels like? LOL Just don't know what else it could be.

Chlorinated water is pretty much 'safe' to swim in any level that doesn't turn your swimsuit white -- it may not be 'comfortable' to swim at really high levels, but unless you spend 24 hours in the pool at, say, 200ppm, I don' think safety is going to be an issue.

There's some pretty random history behind the EPA mandated "don't swim till levels drop to 3ppm" warnings, that I can't go into here. But at the same time the EPA generated those warnings, they were allowing drinking water treatment plants to operate with NO upper limit on chlorine in drinking water! Even now, there's only a 4ppm 'warning' limit, which means basically, "OK, guys, start working on getting that chlorine level down, but no, you don't have to call your customers." It's sort of a left hand doesn't know the right hand thing.

Regarding sticky -- yeah, salt is sticky. I just converted a customer's 200,000 gallon pool to salt, and I find I tend to rinse my hands off afte working with the pool, because of that feel. But, the country club members all seem to like it, so I'm happy.

I get that sticky feeling on my hands when I'm shocking the pool. It's like a sticky soapy feel. If I pour 6% Bleach directly on my hand, it's the exact same feeling only more pronounced. Could it be that the natural oils on the hands actually saponify into soap? Anyway, the sticky feeling disappears once my Chlorine levels come down.
