Crystal clear pool until you get in it then it clouds up

[JohnnyW]

My pool stays crystal clear all the time. Well that is until people get in to swim then it clouds up after just a bit of splashing around. Not super cloudy but enough you can't see bottom on the deep end. After swimming is down, it take about 24-36 hours then it is crystal clear again. All my water parameters are great according to TFP's calculator. (I don't have exact number right now)

Is this normal or do I possibly have a problem?

post up some numbers so we can see, it may be a high CH but lets see what you have

Yeah, tell us at what level you normally run your chlorine? That is a very fixable issue.

Sorry it took me so long to get back.

Current check of numbers at dusk. Last time I added chlorine was last night about 9pm.

FC : 7.4
CC : 0
PH : 7.6
TA : 90
CH : 320
CYA : 30
Borate : 50*
Water temp : 86F

* I only estimate the borate level to be 50. As of right now I have no way to test for borates and estimate 50 because I followed the recommended dose of boric acid to achieve a borate level of 50. What testing method do you recommend? What strips?

According to the TFP pool math calculator, all of those number are good for a plaster pool using liquid chlorine.

Any input?

Just throwing out ideas. Is it possible dirt or pollen is getting stirred up off the bottom? Can you replicate by brushing or running a robot if you have one?

 

[JohnnyW]

I thought of that. Nope I can run the Polaris for hours and still crystal clear.

That sounds like insufficient brushing to me.

You're letting your guests loosen the dust that's stuck to the walls instead of the brush. If I slack off, when I do brush, the water can look pretty hazy for a couple hours afterwards.
