Winterizing A Hot Tub

Water Chemistry For New Spa Owner

Winterizing A Hot Tub
Q:
How do I winterize an outdoor hot tub? I have a hot tub, approximately 8 years old, that I would like to winterize. I live in MI, so below freezing temperatures for an extended period of time is expected. My tub appears to have two fiberglass layers, which air is driven through (it has small holes all around the inside of the tub). This is nice, but I am afraid if I don't add some type of anti-freeze I can't guarantee some water won't remain in the system and destroy the tub.
A:
You are correct in thinking there is a possibility of freeze-thaw damage. Unless you can remove most of the water in the lines and other collecting points there is a possibility of damage.

To help lessen this likelihood you should add a propylene glycol based antifreeze in order to afford freeze-thaw protection.

Using Soft Water In A Spa
Q:
I recently purchased a spa and my home has a water softener. Will the soft water affect the chemicals differently? Is there special care required?
A:
The very fact that you have a water softener means that you have a mineral problem in the source water. You most certainly are better off using softened water, in your situation.

The softened water will require that chemical be added to optimize the pH, total alkalinity and hardness. It's worth it. Once optimized, maintain as other spa. Enjoy the spa.

Water Chemistry For New Spa Owner
Q:
We are new spa owners and have a four person fiberglass spa. What is the best way for us to learn how to keep our spa ph and chlorine levels balanced?
A:
Most lines of spa chemicals come with information on usage. Your spa dealer should be able to assist you.

There is no rigid procedure. Generally speaking the quantity of chemicals needed for proper sanitation is related to the temperature, number of bathers, duration of usage and type of sanitizer. Always test sanitizer level before and add additional quick dissolving shock ( such as Spa Clear OXY-SHOCK or SUN-BRITE for Spas) to boost the sanitizer level. Add some after each use to assure complete removal of bather wastes. After a while you'll get the feeling of what your particular situation requires.

Adding some Spa Clear pH Buffer or pH Perfect will help stabilize the pH and make control a much simpler thing.
