2. A blue bucket may be OK, so long as it's not so dark blue you can't seen the bottom clearly.

3. Bucket test for lime softening:

• fill the bucket w/ ~4 gallons of pool water.
• add 1 tablespoon of bleach & mix.
• add 1 tablespoon of either pH UP (sodium carbonate) OR Arm & Hammer Washing Soda
• cover and wait 24 hours
• inspect; note results; recover & wait 24 hours
• inspect again; report results

4. Pool test:
Add 2 cups of washing soda directly to the skimmer (first remove any tabs present)
After 1 hour, check filter pressure; clean if needed; repeat dose.
Repeat 2 more times (8 cups total)
Wait 4 hours; test pH *and* total alkalinity.

5. Order a K2006 -- to run down your chlorine demand, you'll need a more accurate test than the HTH 6-way

Lemme know if you have any problems.

Arm & Hammer Washing Soda? Is that different from 20 Mule Team Borax? Or no difference?

[Watermom]

They are not the same thing. Washing soda is sodium carbonate. It will raise pH and alk. Borax is sodium tetraborate. It will raise pH without affecting alk much.

k2006 kit received today. Bucket test and pool test results added to history remarks along with latest test details. FC & CC 111. Algae bloom seems to be under control. Chlorine level seems to be being maintained. Will continue to monitor closely. For pool of my size, what should normal expected liquid chlorine addition on what basis should be expected to be added? (1 gal per day, 1/2 gal every other day etc.?)

In your pool, each gallon (4 quarts) of 6% bleach will add 3.6ppm of chlorine. Use that as a reference to help you figure out doses of bleach to add. With a CYA of 90, you need to be keeping your chlorine between 5-10 all the time or risk an algae bloom. And, when you do need to shock, your shock level will be 20ppm. Test the chlorine (and pH) each evening. At that time, add enough bleach to get the chlorine back up to 10ppm. With a CYA as high as yours is, you may find that you can add bleach every 2 or 3 days instead of daily without the cl dropping below 5ppm. You'll soon learn how your pool behaves through testing with your kit and through observation of your water.

By the way -- you might want to try those chlorine tests again. You don't have a FC and a CC reading of 111. This testing demo may be helpful to you:
