Indoor hot tubs (sometimes called spas) don't need stabilizers unless they are positioned under a sunroof or in a room with large windows. And since sunlight affects the chlorine levels in the water, stabilizers are necessary to maintain the chlorine efficiency needed to keep it clean and user-friendly.
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.
Stabilizer - if it is too low, you add cyanuric acid. If it is too high, the best option is a partial drain and refill with fresh water, but that may not be necessary depending on how high it is.
Add stabiliser (Cyanuric Acid). It is important to add this BEFORE you add chlorine. Stabiliser acts as a sunscreen for chlorine, protecting it from UV rays that cause chlorine to dissolve. The stabiliser will create a perfect foundation for chlorine to work more efficiently.
Unlike chlorine, which can be stabilized by cyanuric acid, bromine doesn't have a stabilizing partner chemical. We think it's best for indoor hot tubs, or at least ones that are outside but not in direct sunlight.
You will find that after oxidation of your bromides using a non-chlorine spa shock your bromine level will spike, and that's because you are really shocking with bromine!
Liquid shock contains no chlorine stabilizer (cyanuric acid) and thus is useful for use in commercial indoor pools and/or when cyanuric acid levels are high.
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).
When the product reaches the filter, there may be a temporary increase in filter pressure which will dissipate as the product dissolves. You may swim immediately if Stabilizer was added through the skimmer, otherwise wait 12 hours to swim until all product in the pool is dissolved.
Does pool stabilizer reduce the total alkalinity in my pool? It doesn't reduce it, but cyanuric acid in the pool contributes to a part of your total alkalinity reading and can cause you to believe that your alkalinity levels are higher than they really are.
Cyanuric Acid
CYA or chlorine stabilizer) is the most common chemical that raises total alkalinity. CYA stabilizes your chlorine and prevents it from evaporating due to the sun's UV rays. And it also acts as a buffer to the acidity caused by chlorine.
If the pool is clear, but has no chlorine, then it is best to shock the pool first, wait at least an hour, and then add the stabilizer. It is recommended that you add stabilizer when there is a measurable amount of chlorine in the pool.
– Stabilizer is a type of acid, so too much deducts from your Alkalinity reading. – Stabilizer bonds with chlorine- too much stabilizer can affect how well chlorine bonds with contaminants, making it less effective at sanitizing the water.
It is often referred to by several names—chlorine stabilizer, pool conditioner, chlorine pool stabilizer, among others—but basically, it is a chemical additive that functions to stabilize and extend the active life of the chlorine in the pool water.
Yes, you can use baking soda as pool stabilizer, but the baking soda will also raise the alkalinity level.
As a quick refresher, total alkalinity is the measure of the ability of water to resist changes in pH, or its "buffering capacity." Cyanuric acid, also called stabilizer, is commonly used in outdoor pools to reduce photodecomposition of available chlorine.
No, pool shock and a stabilizer are not the same thing. No, these are different concepts that serve to clean the pool. A pool stabilizer is one of the chemical additives in liquid or granular form that is needed to adjust the water balance in the pool (pH, alkalinity, etc.).
Too much stabilizer can cause your chlorine to become less effective at killing bacteria and algae, and it can also lead to cloudy or hazy and unsafe pool water.
Adding chlorine besides the shock can increase the chlorine content in the water which can make the entire shocking process useless. Hence, it is better if you don't use the shock and chlorine at the same time. The best time to add chlorine to the pool water is after you have shocked the pool.
When you have too much calcium hypochlorite, you start to see calcium chunks in your water, and these will clog up your pipes andwater filters, and sit in your spa water. It can be uncomfortable, annoying to clean up, and if there's too much of it, you might need to drain your spa to clear out the pipes and filters.
Generally it is recommended that you shock your hot tub once a week – more often if it's seeing heavy use. If your levels are all good, but the water is a bit cloudy or doesn't quite smell right, it's time for a shock.
SHOCK TREATMENT:
ADD 1 OZ. OF SHOCK TREATMENT TO SPA EACH WEEK FOR 150-250 GALLON SPAS. ADD 2 OZ. OF SHOCK TREATMENT TO SPA EACH WEEK FOR 250-450 GALLON SPAS.
