My pool builder opened our pool about a month ago. As the pool was built late last summer, its the first opening we've had. Pool builder says he typically adds sequestriant when he opens his pools. Well when he came out last month, he didn't have the sequestriant with him and said he would drop it by the house. I figured it couldn't hurt to add it when I received it. Cut to today, where I have everything fairly well dialed in (I have a SWG):
CYA 40 (still adding...)
My question is: should I add the sequestriant to the pool? I have a plaster pool, we use city water and I don't believe it contains a big amount of metal content (I've scanned the Albuquerque Water Authority reports at http://www.abcwua.org/content/view/564/841/). Any downsides?
