Stabilizers in Hot Tubs
This increased cleaning time is acceptable for most swimming pool applications but is problematic in hot tubs where the pseudomonas aeruginosa bacteria (hot tub itch) may be present. Because of this, chlorine stabilizer should not be used in hot tubs and spas.

Can you add stabilizer to hot tub?

Hot Tub Stabilizer 101

Hot tub stabilizer is used to bond with the chlorine, preventing this reaction. It stops the chlorine from quickly breaking down, eliminating the need to constantly be adding new chlorine and saving you money by using fewer chemicals.

Should you use stabilizer in a hot tub?

Because chlorine is so unstable in the presence of the sun, a hot tub stabilizer is needed to prevent its degradation. Hot tub stabilizers are usually composed of cyanuric acid which easily binds to chlorine molecules. These bonds make the chlorine much more stable and more effective at eliminating bacteria and germs.

What happens if stabilizer is too high in hot tub?

If the stabilizer level is too high in a pool, it will lock the chlorine molecules, rendering them ineffective as a sanitizer. This usually happens as a result of using chlorine tablets that contain cyanuric acid.

What to add If stabilizer is low in hot tub?

If it is too low, you would add an alkaline material, typically sodium carbonate or sodium bicarbonate. They will usually be labeled pH up or increaser and ph down or decreaser. Stabilizer - if it is too low, you add cyanuric acid.

How to fix cloudy hot tub water in three easy steps!

Is shock and stabilizer the same thing?

Pool stabilizer is also known as pool conditioner, chlorine pool stabilizer, chlorine stabilizer, or Cyanuric Acid. And you can buy this chemical additive as either liquid or granular (powder). It's also included in chlorine tablets or sticks (called trichlor) or shock (called dichlor).

Is cyanuric acid the same as stabilizer?

In the pool industry, Cyanuric Acid is known as chlorine stabilizer or pool conditioner. Cyanuric Acid (CYA) is a pool balancing product used to help chlorine last longer. Chlorine, in its natural form, is unstabilized—which means it degrades when exposed to sunlight.

What is cyanuric acid in a hot tub?

Cyanuric acid (CYA), also called stabilizer or conditioner, is used in pools and spas exposed to the sun to reduce the rate of decomposition of available chlorine by ultraviolet rays in sunlight. Stabilized forms of chlorine, such as dichlor and trichlor, contain CYA in their formulas.

What causes cyanuric acid in hot tubs?

Direct sunlight received by your pool

Without any stabilizer, the sun can destroy up to 90% of the chlorine in two hours. The energy contained in UV light from the sun causes the hypochlorous acid and hypochlorite ions formed from the reaction of chlorine and water to break apart in a process called photolysis.

Is cyanuric acid necessary in a pool?

But not every pool owner needs to worry about CYA levels. Because cyanuric acid protects chlorine from the sun, it's really only required for outdoor pools (or indoor pools with some ultraviolet light exposure). CYA stays in a swimming pool for a long time, even after the water evaporates.

Can you put stabilizer directly in pool?

There are two methods you can use to dissolve stabilizer into your pool water. You can either add the stabilizer to a pool skimmer box sock and hang the sock in front of the return jet or place it in the skimmer box. Or you can simply mix it in a bucket of water first and dump it into the skimmer box.

What is a substitute for pool stabilizer?

Because of the importance of stabilizer, there are unfortunately no alternatives. If you stopped using it, you would continually struggle with chlorine levels, bacteria, and algae. We understand that all the chemicals needed to keep a pool looking healthy can add up and become costly.

Is baking soda a pool stabilizer?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.

Do I really need chlorine stabilizer?

The addition of a cyanuric acid stabilizer to pool waters treated with chlorine is necessary to protect the active life of chlorine and its derivatives in the waters from the damaging effects of the sun's ultraviolet (UV) rays. When exposed to UV rays, chlorine evaporates rapidly.

Do I need chlorine stabilizer?

A swimming pool stabilizer is a chemical that helps protect your chlorine chlorine so it can effectively sanitize your pool. It does this by stabilizing the chlorine molecule that would otherwise breakdown in direct sunlight. You should only add stabilizer if your levels are below 30ppm.

What can I use instead of chlorine tablets?

What can you use instead? Bromine — considered a safe substitute for chlorine. Looks for BCDMH tablets, which are typically 66% bromine and 27% chlorine. If unable to find, you can use just bromine but it may leave the water a dull green color.

Does liquid chlorine have stabilizer?

Liquid chlorine is an unstabilized chlorine and does not have any stabilizer (cyanuric acid or CYA) in it. This means that if used in a pool that is located outside and the water has no stabilizer or conditioner already in the water, the UV rays in the sun will degrade the chlorine in about 9 hours.

Is baking soda a substitute for pool stabilizer?

Baking Soda is used for raising the total alkalinity of the pool, which is the key to keeping the ph in balance. It's not a stabilizer.

Do chlorine tablets contain stabilizer?

This package of trichlor chlorine tablets can treat pools, spas, and hot tubs that have up to 5,000 gallons of water. Due to the stabilizer in these tablets, the chlorine released into the pool water is resistant to UV radiation, slowing the production of chloramines.

Do I add stabilizer before chlorine?

When all the other chemicals, such as chlorine. pH and alkalinity, are balanced, add the chlorine stabilizer. Add the stabilizer only after the filter has been backwashed to ensure it is cycled through a clean filter. Add the stabilizer slowly through the skimmer as per the product's instructions.

How can I add chlorine stabilizer without a skimmer?

Here are the steps to follow if your pool has no skimmer:
  1. Add warm water in a bucket to about halfway.
  2. Wear your safety gears like gloves and goggles.
  3. Add the recommended dose of CYA into the bucket. ...
  4. Pour the mixture around the pool – try to cover all corners.

What is the best way to add stabilizer to pool?

Here are a few tips to have when adding a stabilizer to your pool.
  1. Step 1: Put on your protective gloves and eye goggles.
  2. Step 2: Half-fill a bucket with a warm water.
  3. Step 3: Pour a dose of CYA into the warm water and mix. ...
  4. Step 4: Pour the mixed solution directly into your skimmer.

How do I raise the cyanuric acid in my hot tub?

To raise the cyanuric acid level in your spa pool, you need to add a chlorine stabiliser product containing cyanuric acid. Follow the dosage instructions carefully in line with the volume of your spa or pool water. If unsure, add small amounts and test.

When should I add cyanuric acid?

Most often, the only time you'll need to add any significant amount of CYA is when you open your pool for the summer. After that, if you use stabilized chlorine each week, you're adding a little CYA every time.

Does bleach have cyanuric acid?

Regular bleach, or sodium hypochlorite – contains no cyanuric acid. Household bleach is normally a 5% or 6% strength, while commercial strength bleach for pools is generally 12.5% strength, and delivered by truck and hose.
