Newbie, I think I know the answer but....

Example -- in 10k gallons of water, a gallon of 6% will add 6ppm, 12.5% will add 12.5ppm, etc.

I'll have to take a look, if I remember correctly Chlorine is not that much more and is at 10% I have some powder shock and chlorine, and currently put three lbs in the pool at the request of the pool supply center. so I'll do a check again later tomorrow.

The Kreepy Krauly is staying on now and has stayed moving for 3 hours now. Yay!

It is usually best to either follow the advice here on the forum or that of the pool store. Sometimes trying to do both makes it difficult to get a pool cleared up and get the chemistry balanced. What kind of powder shock did you add?

Sorry, Power Powder Plus?

Trying to get an idea as to what do when going with liquid chlorine (or bleach) as I have no idea how to use it.

What is the ingredient in the powder?

Using bleach is easy. Your needed chlorine level is based upon your CYA level. (See the Best Guess table in my signature below for more about that.) I use bleach exclusively. Each evening I test and add a little bleach. My CYA is usually around 35-40, so I keep my chlorine between 3-6ppm based on the Best Guess chart. So, when I see what my cl reading is when I test in the evening, I add enough bleach to get back up to 6. That's all there is to it. I am diligent about testing and don't let my chlorine levels get too low. If you do, you risk an algae bloom and then have to shock up to the needed level shown in the Best Guess chart. Very easy. For reference to help you know how much bleach to add, each quart of 6% bleach will add about 0.8ppm of cl to an 18K pool. So, while your CYA is 20, you'll need to keep your chlorine between 3-5ppm all the time except when you are working to clear it. Then, your shock level will be 12ppm.

You may want to bump your CYA up just a little. 20 is pretty low. We usually suggest around 40-50. Some powdered shocks have CYA in them, thus the reason for my question about the ingredients of the powder. If what you used was dichlor, then that would have added some additional CYA. If your powder was cal-hypo, then it wouldn't have and you'll want to add a little CYA separately. We'll decide that after you tell us the ingredients.

Thanks,

Calcium hypochlorite is what it says on the package

OK. That doesn't add CYA. For now, keep your chlorine at about 12ppm while you are working to clear this up. After its under control, then you can bump the CYA up a bit. Ask more about that at that time.

For now, test as many times per day as you can (no such thing as too often) and each time, add enough bleach to get back to 12ppm. The more consistently you can do this, the faster it will clear. Run the pump 24/7.

Sounds like a plan thanks.

Well the pool is clear and the algae is gone. Just have to deal with all the other issues. Currently the pool is at

FAC 0
TAC 0
pH 7.6
TA 80
CYA 25
TDS 800
Phosphates 0

It still does not want to hold the chlorine for very long. Guess I still need to bump up the CYA

Thanks

How often are you adding bleach and when you do so, how high are you taking the cl level?

I added 3 lbs of powder chlorine yesterday afternoon. This reading is this morning. I then added conditioner this morning to raise the CYA I have not added chlorine/bleach or tested yet. I'm thinking of adding the chlorine at night, hopefully it will last a little longer.
