    The rain effect

    My wife left the pool cover off in a heavy rain. It added about 2 inches to the pool level. While the water is clear, FC 5.5, CC 0, and everything seems nice and clear, the water just doesn't have that "sparkle" it did before the rain. It used to look really crisp and now it seems a bit dulled. This is so subjective because everything measures perfect and looks right. I cannot measure the "sparkle" or crispness of the water, so I just cannot describe it. The only thing I can think of to get that sparkle back is to shock my pool to 20ppm FC, which is how I got it the last time. Any thoughts on this?

    To my pool store owner, nothing is more important than my pool and my money.

    Filter. The rain usually carries some dirt in with it, so up your filter run time fro a few days and you should be good.

    Itabb, in my area, 2" of rain tends to elevate my pH to 8+. A dosage of acid usually tends to bring the sparkle back you speak of. Check your pH reading. Good luck.

    PH did go up a bit, and I brought it back down to 7.6 from 7.8 the next day. I thought that was just normal with SWG and TA 100. I'll run the pump overnight and see how that works out. Good idea.

    We have had excessive rain and even with the cover, there is the rain hitting water and our PH jumped, leaving the water dull and almost but not quite cloudly looking. But, then my TA was already high before that and rain does dilute your chlorine too. A bit of acid brought both down and a bit of extra chlorine on top of that cleared it right up.
