Rookie of the day- Hello!

I'm loving this forum, the school and info are excellent resources.
My question is regarding balance of chemicals. Which comes first, how long do I wait to test and add others, I don't want to play the over/under game all summer.
Also HOW are they added, dilute first and dump, add straight to pool, sprinkle gently, pour into strainer🙄?
I could really use your help right now before I have to hire a pool-guy. 😁
Thanks mucho! I'm so happy to have found you!
High desert of SoCal, all day sun 100°F, and we have high calcium hard water.
Water is 78°F, 0.0FC, 7.8pH, 120TA, 1600CH, 0CYA.
Where do I start?

The 1,600 calcium hardness seems unlikely. How are you getting that result?

If the numbers are accurate, you need to get the pH down to 7.2 soon and get some liquid chlorine to raise the fc.

Welcome to the forum!
Recommended Pool Chemicals - Trouble Free Pool discusses much of what you ask.
What test kit are using for your water chemistry data? And I doubt your CYA is 0 is you are using Trichlor as your signature states.
I suggest you read ABC's of Pool Water Chemistry and consider reviewing the entire Pool School eBook.
Test kit is HTH 6-way. CYA test never got cloudy. I was able to see the black dot always. I used 1 packet HTH Super Shock last Sunday, added two 3" trichlor tabs to the floater on Monday.
I will go back to school. 😣

It's a new fill, so no time to build up cyanuric acid yet. I wouldn't be too sure about the calcium hardness result as that is probably not accurate.

You will want to get a FAS-DPD test for FC. Or just a full proper test kit.

I see this is a new fill. You need to add CYA to get to 30 ppm. Then use liquid chlorine every day to maintain FC based on the FC/CYA Chart
