Beginner - First Time Tester

[Bailey812]

Hello! I did a Standard Sampler Test with my new TF-Pro kit, then ran real test using pool water.
Can you give this a look over and let me know if these look within reason/I'm on right track before I start adding Liquid chlorine?
Water is clear, but fighting green algae along tile lines.
Thank you!

Welcome to TFP! Good job testing your own water. Now for the good and the bad:
1 - Your CYA is too high and you have algae. Even if just at the waterline, it's there and you need to start a SLAM Process. Problem is with the CYA that high it requires a very high FC level. Would you be willing to exchange some water first? If you exchanged about half of the water, your CYA should fall down to about 50-60. That would be much better.

If you elect to exchange some water first, do that, run new tests, and post back.

2 - Now if elect to just go forward with what you have now, this is what I would say:
a. Lower the pH to around 7.2-7.4 with muriatic acid.
b. Increase the FC to "39". Yes, that high but required based on that elevated CYA as noted on the FC/CYA Levels. Maintain that elevated FC level and follow the SLAM Process page until you pass all 3 SLAM criteria.
c. Double check your CH test. That's a bit low. Make sure you are going all the way to the end of the test to the light baby blue color.

Personally, I would exchange some water first to get the CYA down to around 50-60, then start the SLAM, but your call. Let us know if you have any questions.

Very helpful, thank you! I am going to exchange the water and retest.
