What would you say this pH level is?

[Household6]

 

[mknauss]

Elevated.

What is the FC?

FC is Zero.

Seems to me the tube goes yellow, orange, pink so I was hoping this fell at 7.7 to represent red.

Never realized exactly how much aeration could affect pH! (Water level got low and have a jet that’s cracked allowing water to aerate. It has been a beast to get down!)

What is your TA?

 

[duraleigh]

the colors going from low pH to high pH are
yellow 6.8 and lower
yellow orange 7.0
orange 7.2
orange red 7.4-7.5
red 7.6-7.8
red violet 8.0
violet 8.2 and higher

Your pH is 7.6

 

[mknauss]

Next time, try 4 drops of reagent. It should make the colors match better.

 

[Household6]

Using 4 drops it’s pretty much a dead ringer for 8.0

More so in person than it appears in photo.

I'm seeing about 7.6. I think that most people read pH higher than it actually is.

You have to go by the hue more than anything else.

 

[mknauss]

Use a white background. Sheet of paper, etc.

Notice the white vinyl fence in the background.

Is that 7.6 from the first photo or the second? Or both?

 

[JamesW]

It looks like 7.6 for both. Maybe get a pH pen if you want to be sure.

What's the TA?

 

[SteelBlue]

I too have had some difficulties discerning the color match. Is the pH meter considered by TFP to be a more accurate means of measuring pH?

You need to regularly calibrate pH meters using pH 7 Standard Solution to maintain its accuracy.

So, they are a little more of a pain to use?

I too have trouble distinguishing the PH in the kit and use the PH Meter to verify what I'm seeing. In my 1 week of use, I have not had to calibrate it at all, but its pretty darn easy to use. You turn it on, stick it in the water and it gives you the PH almost instantly.

If a pH meter loses calibration and you don’t realize it it can lead you well astray. If you get pH readings you don’t expect you need to double check it with the OTO test.

OTO?
I think you mean pH reagent or calibration solution?

I mean redo the pH test using the Taylor OTO K-1000 Basic pH Test.
