Open Green and Cloudy & No CYA

We had this same discussion last year. Here is the post link.

TLR- I have a deep end that is about 5 1/2', sometimes deeper when the water runs high after it rains a lot.

I use a chlorine calculator that I thought I found on here. It is an .exe and it calculates in L as opposed to gallons. If you have one you like to use then let me know. From what I can tell if I want to increase 10 ppm then I need to add 6L of chlorine.

May not work with Windows 8, unless you run it in a compatibility mode.

Sorry I didn't remember. We answer thousands of posts on this forum each year and there is no way to keep details straight! You might want to put in your signature --- AG 27' with 5-1/2' deep end. You can edit your signature by clicking on the tab in my signature.

I never thought you would remember. I just posted to save us the time of going over it again .

FC is 1. CC does not register. I would think that the CC would be high since that means it is bonding with all the stuff I want to kill? Adding bleach now and will check back in an hour.

If CC doesn't register, that means it is 0 which is what you want it to be!

1.5 hour after adding 6l of bleach I am at:

FC 1.8
CC 0

I figured 6 liters would get me to 10 ppm. Do I hit it again for 6 more liters before I go to bed?

[Watermom]

Yes.

I think I need to do a bucket test to figure what this pool needs. Right now I feel like I am feeding a bottomless pit.

6:45 am the FC was 1.8 CC was 0. Added 1.5 gal bleach and checked again at 830. FC was .8 and CC was over 2. Could this rapid burn off be from the sun? I added a dose to get me to 10 ppm and in under 2 hours it was lower than when I started?

Will adding CYA at this point help with any chlorine demand? I wonder if getting the FC levels to hold longer will help.
