I’m having my pool installed later this month

Welcome to TFP! 😀

When you get a chance add your pool information to your signature. Settings/signature.
Helps the experts help you and saves you entering it each time you have a question. Check others for examples. If on a phone, turn sideways to see signature.
 
Welcome to the party. Solid advice in both posts above me. I will add you need a reliable test kit to take ownership of your water. The TF-100 from tftestkits.com is the gold standard. It will pay for itself many times over.

You are fortune to find your way here *before* you needed it. Many people come after and not only do they come in with lots of baggage to fix, they have lots of bad habits to fix first. You will hit the ground running and be trouble free from day one.
