Welcome to TFP!
Nope, not true. But your pool type could influence our guidance, so be sure to update your signature with all of your pool and equipment info. See mine as an example. Without a doubt you'll need some stabilizer for the CYA level, some liquid chlorine, and perhaps some muriatic acid to lower the pH if it's too high. But be sure to test your water with a TF-100 or Taylor K-2006C test kit to be sure. Any other testing is almost a waste.

Winterizing a pool is essential for keeping your in-ground pool protected during cold-weather months. This Pool Repair guide will show you how to do it.
