Yellow Staining

Sounds good, just remember that the stabilizer take several days to dissolve, so in the meantime you're going to have to add chlorine daily to keep the algae gone.

Thanks, Add 4 gal bleach today. To bring the chlorine to 0 I added some chem remover to eat the chlorine. Taking more bleach to eat that up.
Pool is a little green, hoping from the heat and low chlorine levels.
I will check levels again tonight after it has circulated a few hours.

Readings now
TC - 1
FC- 0
PH 8.6
TA 185

Should I get ph down prior to adding bleach? I have a few gallons of liquid shock, thinking of using that to bring chlorine up.

Yes. Your bleach won't work if pH is so high. Add acid to lower it--aim for 7.3. The acid should only take a few hours to work, then shock the green out of it!

I totally don't understand what you're saying in this post....what chem remover did you add to "eat the chlorine", and why did you lower the chlorine and then have to use the "liquid shock" to bring it back up? I must've missed something here..........

Also, if your FC is 0 and the TC is 1, then you still have CC's that need to be dealt with--which you need to do by shocking the pool...that's why it's greenish looking.

Edit: I just realized this post is a few days old..I've been away out of town. But I still don't understand what you're trying to do....did you get it worked out?

First I am really surprised that your ph stayed that high using the ascorbic acid. Your ph was probably even higher than you thought. It usually takes the ph way down. Second, you didn't say you put in any sequestering agent. You will need to do that asap - it should also take the ph down. Anytime you have your ph above 7.4 and you have metals in your water, when you add chlorine the metals will fall out and stain the surface of the pool. If you are having algae problems, then you need to add the sequestering agent, make sure your ph is no higher than 7.2 and then shock. I would also use some algaecide because it is hard to keep chlorine levels up after doing an ascorbic acid treatment. The remaining ascorbic acid eats the chlorine.
