We recently bought a new house that has an in ground Anthony Sylvan pool. Its running the Nature 2 system. After reading on here for a few days now it does not look like you guys are a big fan of the Nature 2. I ordered the Taylor test kit. Currently using a dropper kit from Home Depot.

I had some black algae when we moved in. Local pool store said to scrub the walls with a metal brush along with some aglicide and some other high dollar chemicals. $150 dollars later the black algae seems to be under control but I am constantly fighting light green algae around the edges. Water is crystal clear usually. Looks like I may have some staining from the high Cl shock to kill the black algae and the copper from the Nature 2.

Do not know my stabilizer level yet, most likely very high, we have been using tabs in skimmer since we moved in, about a month ago.

If you maintain high CYA levels and have to maintain high Cl levels, is that bad for your body and swimsuits? Would it be better to get the stabilizer level down so you can maintain a reasonable Cl level. The Cl products all have a warning to not get in the water with Cl concentration greater than 4 ppm. Why?

Thanks for your help
