Open Green and Cloudy & No CYA

Your 12.5% bleach is just fine.

It was late when you added bleach so you may have not had time but when you are trying to determine if you have a chlorine demand, we like to be able to measure overnight chlorine loss. The best way to do this is to add chlorine when the sun is off the pool in the evening. Then, a couple hours later test so you'll have FC and CC numbers to compare with the next morning's readings which should be taken within an hour of sunrise.

I will do that tonight and tomorrow morning.

My first reading was .6ppm, but 1.5 hour after sunrise, but no time to get full FC reading. I added a gallon of bleach, just to keep the pressure on the algae, but I figure it will be gone by lunch.

I hope that since there was SOME chlor this morning that I an not dealing with the larger issue.

By the way, what is your wall height on your pool? I think you may be overestimating the volume of your pool. I'm assuming it is 54" (same as mine ) which means your water level is around 50 inches. This puts your volume at more like 18K gallons. I was trying to determine how much chlorine a gallon of 12.5% bleach would add to your pool (assuming it is that strength) and need an accurate volume to do so.

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.

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!
