Cloudy Water & CL Going Going Gone

[Jakebear]

Can someone give me a hint at what might be happening?

During the last 10 days we have lost an average of around 5 ppm FC per day.
We have been trying to keep the FC over 5ppm because Ben’s BG Chart says to with the CYA at 60ppm.
On Sunday the FC was 4 so we put in 17 oz Cal Hypo By Monday PM the FC was 4 again.
We put 48 oz Cal Hypo in on Monday Evening (mistake should have been 39oz) to raise FC to 12 ppm with an expected loss of 6 ppm during the day. The water got very cloudy.
Tuesday Morning FC was 13 ppm and 7.5 ppm by dark --- Added another 22 oz Cal Hypo. Water was still cloudy.
Wednesday AM FC was 10.5 ppm and 7.0 ppm by dark.. --- Added another 14 oz Cal Hypo. Water is still very cloudy.

We are using up a bucket of 65% Calcium Hypochlorite we bought before we found this site and have not had any pucks in for about a month.

Air temp has been close to 95 in the afternoon every day.
Water temp 82 F in the mornings 87 F when the sun goes down – Running solar system at night to take some heat out. We run the robot everyday to gather up minor dirt and bugs + calcium dust that precipitates out. There is no algae visible.
The pump has been running 24/7 since it got hot.

This evenings test results are:
pH 7.5 Titration
FC 7.0 ppm (FAS-DPD)
TC 7.0 ppm (FAS-DPD)
CC 0 ppm (FAS-DPD)
TA 90 ppm (by titration)
CH 260 ppm (by titration)
Phosphates <100 ppm
EDIT --- CYA 60 ppm with R0013 kit
ORP = 698

These numbers have been consistent throughout except the CL that goes up and down respectively with the additions of Cal Hypo.

The two main questions are ---
Why is the water remaining so cloudy? We have never had this problem before even after shocking.
Why are we loosing so much FC over a 24 hour period?
Should I be worried?

What is your CYA level?

[Jakebear]

My third sentence from the top states CYA 60 PPM --- but I will edit my results from today so nobody else misses it

You need to take your chlorine level up to 20ppms and keep it there. You are fighting something , that's why your chlorine is dropping overnight. You have to be consistant - get your chlorine up to 20ppms with regular bleach, and test 3x a day and bring it back to 20ppms. If you stay consistant, your water will clear faster. Everytime you see it under 20 - add more bleach. You can use the bleach calc to see how much to add.

So --- Shock --- That's it?

We're OK with that, but it seems like we should have some other indicator, like chloromines or something. Could the cloudyness just be from the heat or excess calcium?

We really don't want to shock with the temp near 100 and all the other indicators are good. We want to swim!!

You can shock and swim! Sometimes the water is cloudy, and the combined chlorine is 0, but the chlorine starts to get eaten up = this is because there is enough chlorine in the water to keep the algae from taking over, but not enough to completely kill it all, leaving you with cloudy water. The good news is that if you take it up to shock levels now, you won't have to continue at shock level because it should kill it all once and for all. If you wait, and the aglae takes hold, it will take a lot more effort to kill it - you will have to keep it at shock until it holds overnight. You can swim with shock levels of 20ppms, just wear an old bathing suit.
