Need help on first time results

Good work on the chlorine. Let it drift down on it's own and then keep it in an 8-15 or so range for the rest of the Summer.

Now, you need to get your pH down right away. Get some muriatic acid, use the bleachcalc, and bring it down into a 7.2 - 7.4 range...sooner rather than later. That chalky substance just may be calcium precipitating out and lowering your pH (sooner rather than later) is the solution.

You can't do anything about your high calcium for this Summer so it becomes imperative that you monitor your pH. Keep the muriatic on hand since bleach has a pH around 12 and it's your only logical chlorine source.

In the rainy season, (or when they lift the drought restrictions) you need to drain half of your pool and refill to get your CYA and Calcium at more manageable levels.

Meanwhile, Happy Swimming!

Starting over after a complete drain and lots of rain here in the Dallas area.

FC 2.5 hard to keep up with all the rain
CC 0
TC 2.5
pH 7.5
Alk 50
Cal 220
CYA 50
Temp 78

I'm using pucks right now inline to increase the CYA while using bleach to shock and increase FC. However, my pool has boulders that extends into the water and I can't seem to keep a green line at the water level at bay. My question now, are the numbers above good enough to add Borax and get the Borate up to 50ppm. I'm hoping that will help with the algae on the rocks.

I'm new to all this too, so this is more a test of my thought process and if I'm wrong, someone else please say so...

With your CYA at 50, you want to keep your FC somewhere between 3-6ppm.

You Alk looks low, you want 80-120. If you add Borax for the algae line, your pH and Alk will go up, so make sure you have some Muriatic acid to drop it down. You might also consider some Arm & Hammer to raise the Alk and your pH may not do much, however, the latest box of A&H I bought also shows pool treatment numbers on the back, so it may also raise your pH.


Everything else seems OK to me...
