Chlorine Lock

[pkhydro]

Just got back from the pool store and their test showed:
CYA 43
TC .8
FC 0
PH 7.4
TA 153
Tot Hardness 94

I'll add the 2 gallons of bleach as you say. They recommended vacuuming. Thoughts?

I had left out one piece of information earlier. I installed a new Hayward pump and filter. Not necessarily to correct this problem.

Vacuum if the pool is dirty but as far as helping with keeping chlorine in the pool, it is not going to have any effect.

[pkhydro]

Vacuumming was to aid in clearing the water. I would only do this if there is actually something to vacuum.

But for now, I should just concentrate on the chlorine?

[Watermom]

Yes. Concentrate on the chlorine.

[pkhydro]

Ok, pool is still cloudy. While vacuuming I ran across an area that threw out some green stuff. A small area maybe four feet in diameter and kind of in the middle.

But, I received my Taylors and:

FC = 2ppm
TC = 1ppm
PH = 7.4
TA = 170
CH = 120
CYA = 30

Saturation Index = -1.15

Water Temp is 90 according to my meat thermometer

Water is cloudy.

Your TA is too high, but nothing to worry about at the moment . . . except that you'll need to keep adding acid to keep you pH below 7.8

BUT . . . your chlorine is too low! Are you adding 2 gallons of bleach each PM?

If you have the Taylor FAS-DPD test kit you cannot get "FC =2 and TC=1". Perhaps you mean CC= 1 rather than TC?
Rule: TC = FC + CC. Therefore TC can NEVER be less than FC.
