Have you tested the CH of your tap water? If you have been using cal-hypo that would account for a high CH result. You can work with that CH by dropping the TA down to around 70 and keeping the pH between 7.2 and 7.5 so you decrease your risk of developing scale.

You can raise your CYA to around 30-35 to keep your chlorine from burning off too quickly. It sounds like you still need to shock the pool. You want to keep your FC around 12 (shock level) until you pass the overnight test.

I would test an unfiltered source, perhaps the outside tap if that is what you use to top off the pool.

You would need 2 gallons, 1 quart of 10.5% liquid chlorine to bring the FC up to 12 ppm to shock the pool. You have already added 1 gallon, so you would need 1 more gallon and 1 quart to raise the pool to shock level.

Tap water 80-90 CH
That is good. If you want, you could drain some of the water to get the CH a little lower or you can manage with the CH you have now by dropping the TA. If you live in a part of the country that freezes in the winter, you will drain some of the water when you winterize your pool then refill in the spring. As long as you stay away from the cal-hypo that should be enough replacement water to bring the CH into line.

I would keep checking the FC every hour or so to make sure you keep the FC at shock level. This is a very important step in shocking your pool. You have to keep the FC as close to shock level as possible. The more you can keep it at shock level the faster the process will go. Then when you get up in the morning check it again and get the FC back to shock level until you have no FC loss overnight.

This is very good advice. Do not worry about your other parameters until your pool is clear. At the stage you describe your water, it may be OK to test and add chlorine twice daily but propbably not less than that. The better you keep the FC up where Ken suggested, the sooner your pool will clear.

All your other parameters can be dealt with later.

Sure. At least that much. You will not waste any of it and you don't want to run out in the middle of the process.

Ok just tested again at night 8pm here :
FC: 4.5
CC: 0.5
TC: 5
PH: 7.3
Okay, you know what to do....get your FC up to 12-15ppm. Tomorrow AM, test first, then add enoughto get it back up to 12-15ppm again.

Brush, vacuum, and backwash/clean the filter as necessary.

Keep that FC up twice daily at least. :lol:

Good morning! Did you add anything between last night's test and this morning's? Bump your FC back up to shock level, keep your filter clean and your pump running. Brush the walls and vacuum if you see any piles of debris. Has the appearance of the water changed any?

As you can see something is eating up the chlorine overnight and it is not sunlight! :) So you need to get the FC back up to shock level and check it as often as possible today and add bleach as needed.
