Disclaimer: This year will be the 1st full season with a pool!

Simple question.. How do you all know what/how much to put in after getting readings? (I tried using the calculator and that wasn't really intuitive as I would have liked, although, I should spend more time with it.)

I ordered and used the TF-100 Kit and got the following results. I'm afraid of adding in too much shock and may raise the CYA.. which I'm trying to avoid replacing water.

Pool was opened last week, added in 6 Gallons of shock, life got in the way and therefore, wasn't able to keep up with it. A week later, the results are below. The water was clear and then it got greenish but mostly with sediments on the pool floor. Just trying to get this thing up and running. Trying to avoid the pool store as I want to learn this on my own.

FC - 1.5
CC - 2.5
CYA - 35
PH - 78


Looking forward to hearing all the advice. Thanks!!!
 
Greenish water and CC - 2.5 means you have to SLAM your pool because of algae, but, others with more experience will chime in, you have to get your PH down first with muriatic acid (assuming you meant 7.8 for PH). CYA is fine for a SLAM!
 
Ok, you have a lot of CC, and from the description of your pool you will need to complete theSLAM Process process to clear it up. Do not use any form of dry chlorine. Only use liquid chlorine or plain, unscented bleach without soil repelling additives, such as chloromax. You did not list a CH test result. While it will not affect whether or not you have algae, you need to know the calcium level in your pool. pH is a touch high, I would bring it down to 7.2 and start the slam.

ok.. How do i bring the PH down.. meaning, how do i know how much to add? What to add?
My CH value is at home. (I left the list at home). The numbers i provided were based on memory when I did the test last night.
Should I used Chlorine such as Chlorox vs Shock?

A little tough love for you...

Under certain conditions, with certain equipment installed, and during certain times of the year, you might (might) get away with servicing your pool once a week. Until you know enough to meet those conditions, you should resign yourself to testing daily, and possibly (probably) dosing something daily.

You can decide to let "life get in the way," in which case you'll end up spending considerable time and money to correct what will come of your pool (just as you are experiencing), or you can get a handle on TFPC and set yourself up with the regime proper pool maintenance requires. Those are pretty much your two choices (not counting hiring a pool service company, or filling in your pool).

Sorry, that's the reality of owning a pool. The good news is, once you get it down, you'll only need about 5 minutes a day, and eventually you'll be able to stretch out a bit what needs to be done, and if you invest in additional equipment you can stretch things out a bit more. But for now, there are no shortcuts...
 
You don't want to use any form of dry chlorine at this point. Only liquid. It can be chlorinating liquid from the pool supply or plain, unscented laundry bleach without fabric protectors added.
 
Hi, TN. If you are feeling a bit overwhelmed with Pool Math on the webpage, try the app. It’s really pretty helpful, and once you set up your pool in the settings, it’s very easy to figure out just how much of stuff that you need to add.

I also recommend checking out Pool School, start with the ABCs of pool water chemistry. once you get a understanding of how all of the different pieces work, it’s easier to figure out what your pool needs.

Thanks for the help everyone. I took Kellyfair's suggestion and looked up the pool math app. It was VERY straightforward. But then I went back and took a look at the math calculator and it actually ended up being pretty easy if you dismiss all the words/selections that didn't apply.
Eitherway, slammed it, used the chart and happy to report that the water numbers are perfect and the whole process isn't as daunting as it seems.

Now... onto the next issue.. Caterpillar droppings in the pool and deck area...
