Hello all, and thanks in advance for your time and consideration.
Bottom line is that I'm a new pool owner and I think I have an algae problem but the pool store seems to think my water chemistry is just fine.
It's a 24' 52" round, vinyl liner pool with a sand filter and a SWG.
I've had my pool about 6 weeks now. All has been well up until this past few days after a heavy rain. Went to the pool store Saturday for a check and they said chemistry was perfect.
Went out this morning and the water is cloudy with a tinge of green. Went back to the pool store immediately and got these readings (luckily I am off today). The clerk seemed unconcerned and had no recommendations:
Calcium Hardness: 352
Total Chlorine: 0.14
Free Chlorine: 0.10
Chlorine Stabilizer: 33
I reiterated that the water was cloudy and seemed to have a tint of green, and she handed me a 1 pound bag of shock, which I added immediately this morning.
However, as I reviewed the sheet they handed me with my water chemistry, and the numbers above seem out of tolerance for even their recommendations- on chlorine alone they recommend a max of 3ppm total chlorine and .6-1.5 ppm free chlorine. I'm actually wondering if she doesn't understand that 0.13 is LESS THAN 0.6...
Now that I have read a bit on the forum, it seems to me that I have an algae problem and need to do something more.
