PH test extremely pink?

[milesvdustin]

Testing PH of just opened pool. Test shows crazy high ph, off the charts. I have added a gallon of fresh muriatic acid now and it still shows high. Keep adding acid?

Pool is green, was clear when closed. Inground, mesh cover. Lots of worms the robot is picking up

If your FC is 10+, the PH test is invalid and you need to wait until the FC dips below 10.

If it's already below 10, any PH out of range looks like 8.2 or 6.8. It could be a 9 and you try to lower it 8.2 to 7.6 and it only really lowers it to 8.6, which still looks like 8.2.

Test, dose, mix, verify. Repeat as many times as necessary when low, or high. *when FC is below 10.

High pH is purple, not pink.

 

[milesvdustin]

It was way above the scale with fc at 0 and with it at 8.5. It was a magenta color, not dark purple.

So the color looks way way more vibrant than the 8.2 on the block. I have a brand new tf test kit pro in the zipper case. The comparator block seems cheap.

i'm taking a stab at ammonia. Can you get FC to hold or does it go right back to zero? do you have zero cya?

Let’s see a picture.

Ammonia has low pH.

What are the Signs that Ammonia is in Pool Water?​

• Disappearing CYA
• High CC
• Low ph
• Inability to hold chlorine level

well, then, as Roseanne Roseannadanna would say, Nevermind.

I will get a picture after work.

I did hold 11 FC overnight with no drop, which seems strange considering the pool was dark green and I just started with the CL 8 hours before dark. The pool is a dark bluish gray now.
CYA measured out at 15-ish and I added 4 pounds, its in skimmer socks dissolving in the pool.

What is the TA?

Is the TA changing?

 

[milesvdustin]

TA was 60, and not changing.

 

[milesvdustin]

Dunno what's going on but now instead of hot magenta it's now a dull brownish red?

 

[JamesW]

TA?

 

[IceShadow]

Looks like about 7.2 - 7.4. Try one less drop of the indicator solution, that sometimes helps match the color blocks better.

 

[milesvdustin]

TA is still 60. FC 5.5, CC 1.5

I'll try 4 drops here in a bit

 

[IceShadow]

Either way the shade is the important thing to match, not the intensity of the color.

 

[milesvdustin]

Looks like a 7.5 with 4 drops in it. FC is at 10.

 

[IceShadow]

That seems about right. I find the pH test is best when you put a piece of white paper behind it instead of holding it up to the sky / a light.

And you're flirting with FC being too high to trust the pH test, might be skewing the colors.
