Draining and refilling is the nuclear option, but sometimes it’s needed. If your chlorine is above 10 ppm and you have a small hot tub, swapping out half the water works like magic. For a big pool, you can do a partial drain—just don’t go over 20% to avoid damaging the liner or upsetting the pH balance.
Think of it like making a strong cup of tea: if you add too much tea, you don’t throw the whole pot away—you just splash in some hot water. Same idea, just bigger. Water dilution is your friend.
But wait—what about the environment?
If you drain, never send that super-chlorinated water into a storm drain. It kills fish and plants. Dump it into your lawn or a garden bed instead—chlorine breaks down fast in soil, and your grass might actually thank you.
