Really confused on cause of haze

[mbar]

I would go to 20 or 25 ppms with the chlorine. Sometimes you just need a higher level of chlorine to reach "break point" and since you are on the border with "cya about 50", then the higher level just might do the trick.


Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . . . 8 ppm . . . . . 15 ppm . . .. 25 ppm

by keeping it at 15, you may be holding what you are fighting, but never getting ahead of it. Try bringing up the chlorine, and see if the clarity changes. The ph could be off a little, but it wouldn't make your water cloud. Sometimes you need to keep the chlorine level high for a week to break down what is in the water.

It also depends what kind of sequestering agent you used - if there are a lot of metals in the water, it could cause cloudiness. The high chlorine levels will break it down and then it will filter out.

Filter is a sand filter. Maybe I need to add some DE to trap this "sediment".

Correction to original post.
ALK is 70
CAL is 110
I will go for the higher CL, but could my haze be from low ALK? Is it low because of the acid that I use to keep pH down? If so, how do I keep the pH down without affecting alkalinity so much? It may not have anything to do with it, but I just thought it would be worth mentioning.
Thanks for the replies and keep 'em coming.

I don't think the haze is from the low alkalinity - it isn't very low, you want alk to be between 80 - 120. You can add baking soda to bring up the alk - it may bring up the ph a little, but that would be ok. Using baking soda will raise the alkalinity and the ph may raise just a little' - then you can add acid to take the ph down - it won't effect the alk much. When you want to raise just the ph you add borax, it won't raise the alkalinity. Hope this helps, ask any questions you may have.

I've never had to raise the pH, I think it is because of the SWG. Is my ALK down because of all the acid I have to use? I think you are right, though, I need to raise the FC. I'm just trying to understand the relationship between pH and ALK. If I get my ALK up some, won't that help my pH not to fluctuate?

[mbar]

Yes, if the alkalnity is stable it helps the ph to stay stable. I would just let them both alone for now, raise the chlorine, kill the rest of what is making the pool hazy, and then work on the alk and ph, they are fine for now.

You got it! I have learned to do EXACTLY what I'm told on this forum. I added extra bleach last night to get it up to 20. I noticed this morning, it looked a LITTLE better. Big problem - I ran out of DPD reagent this morning so I don't know how much it used overnight, I added a gallon anyway. I ordered refills from Ben, but I assume his shipping log is still full. I guess I will try the dilution method. That stuff is still settling in the exact same spots. I guess I will vacuum tonight.

For what it's worth, you may not have to wait for your refills for very long . I ordered refills on 7/11, they were sent out the very next day and I received them on 7/17 - also in TX. Way to go, Ben!
