Hi all -
Just opened my 16k gallon, SWG, fiberglass pool this past weekend. I use the Taylor test kit and water is looking good. My issue is that I did have the water tested by a local pool store (more as a curiosity as I use the Taylor kit to guide me), but I found out my copper level (.6 ppm) was outside the ideal range (0 - 0.3 ppm). I've never had elevated copper levels before which made me wonder where it came from. I am only into my 2nd year with this pool and the pool builder closed it the first winter, but suggested I should hire somebody to close in subsequent winters. So I did that and I now realize that the company that closed my pool this past winter used "ALGA Break9", which has Copper Sulfate Pentahydrate as it's main active ingredient.
Reading thru TFP forums, I learned that many of these algae preventers contain copper and they are generally not recommended. The only time these have been used in my pool is during my most recent closing. So my questions are:
1) I assume for future closings, no more algae preventer?
2) I need to use a sequestrant to "lower" the copper level? (I understand this only holds the metals and eventually wears out...) Is there a specific brand or type recommended?
Thanks in advance,
Charlie
