So far the Apera PH60 seems quite nice. I've been comparing results to the phenol red test with the assistance of my wifey's eyes. :) Good correlation so far. It comes with 4, 7 and 10 pH buffer solution for a 3 point cal. I've also ordered some 8.2 buffer solution for verifying it around...

Was your motivation for this for looks/feel, trying to slow pH rise or both?

Here’s a great way to add CYA. For me it only took a couple hours to dissolve with my pump on high. https://a.co/d/iCGPCMb

Did you read the link in post #2 by @HermanTX?

To me it looks like the mechanicals that are inside of a pressure gage. https://www.marshallinstruments.com/faqs/detail.cfm?id=22

If you ordered the TF-Pro Salt you should not need salt strips. Maybe that's not what you ordered? Ditch the strips and get a drop test kit.

Thanks for the assist everyone! BTW, I've ordered a PH60 as another reference point. We'll see how that goes. :)

So the fist pH adjustment was 15 oz to go down 0.4. When I went back out for the second adjustment I only had 8 oz of Ma left. I added that and 30 mins later it looked just under 7.8 to me. It is easier for me to see the colors in the high 7 range.

Is there a pH meter that is recommended here above others?

30 mins later. Taylor and TF Pro with 5 drops.

TA is 60. I’ll adjust pH down .4 and report back. I understand the approach you describe but I’m limited in my ability to see colors correctly. The problem is mostly with red/green. I seem to be able to tell lighter/darker shades very well and if one color looks exactly like another. Where I...

The purple tinge was messing with me too. I’ve been experimenting with less drops in the Taylor kit and TF Pro. Checkout 3 drops (instead of 5) of R-0014 in the TF Pro kit. Looks exactly matched to 8.2 to me. Thoughts?
