When To Add Stabilizer to a Pool

Most homeowners only add stabilizer to a pool when they first open their pool. Pool professionals and homeowners typically shock the pool until the chlorine and alkalinity are balanced. Next, you can backwash your filter to clean it, then add a stabilizer to the skimmer.

This is ideal at the opening of a season because your chlorine will be off to a good start. You can ultimately waste chlorine if you don’t add stabilizer at the beginning of a season. Chlorine can dissipate quickly without stabilizer resulting in chlorine lock.

Pool stabilizer is just one of many costs to maintain a pool, but it’s worth it when your chlorine lasts longer. Make sure not to over-shock your pool before you add stabilizer so that the stabilizer doesn’t cancel out the chlorine. The cyanuric acid in pool stabilizer is strong, but using too much shock can negate its effects.

How Long After Adding Stabilizer Can I Shock the Pool?

can you shock your pool and add stabilizer at the same time

There is no ironclad rule, but you should never shock the pool immediately after you add stabilizer. The cyanuric acid in pool stabilizer can lock and waste the chlorine. Add too much shock and chlorine to the pool and you risk rendering your chlorine useless.

It takes up to 3-4 days for pool stabilizer to evenly spread throughout the pool and dissipate. Test the chlorine level in your water before you shock the pool to find out if it is even necessary. Wait an additional 1-2 days if your chlorine level is fine.

Never shock your pool after adding stabilizer if the pH and chlorine levels are balanced. That would waste the chlorine you may have to drain and backwash some water to fix the problem. Keep testing strips at your home so that you can quickly check your chlorine and alkalinity before you shock the pool.

Shock Vs. Stabilizer

You need to use both shock and stabilizer to keep your swimming pool in good condition. However, they are quite different from each other and serve your pool in unique ways. Let’s take a look at the difference between shock and stabilizer.

Shock

Shock is a high-dose shot of chlorine that can quickly balance out your free and total chlorine level. If you test your pool and the results show that your free chlorine is lower than your combined chlorine, you need to shock the water.

Use a shock that has 70% to 80% chlorine in it for fast results that bring your pool back to baseline. Shock is separate from the traditional chlorine that you use to maintain your pool. Standard chlorine is great to maintain proper chlorine levels, and shock is great for drastic situations.

You typically only need to shock your pool when your chlorine levels fall too low, or if you notice cloudy water. Shock is also great for killing algae and bacteria. Any homeowner with a swimming pool should keep shock around in case of chlorine emergencies for fast results.

Stabilizer

Stabilizer, also referred to as conditioner, acts to stabilize the chlorine that is in the pool. You would never use stabilizer as often as you would shock, and most homeowners use it once per year. The cyanuric acid in pool attaches itself to the ions of the free chlorine in the water.

The cyanuric acid will strengthen and prolong the life of the chlorine in your pool unless you use too much stabilizer. Stabilizer reacts differently with water than shock does, and it takes as long as 5 days to dissolve. It is possible to experience chlorine lock when you use too much stabilizer, and you may need to drain water.

Drain some of the water out of your pool, refill it with a hose, and shock the water. That way, you can dilute the stabilizer so that your chlorine will last longer.

Related Questions

Can you put stabilizer directly in the pool?

Yes, you can put stabilizer directly in your pool, but it is recommended that you put it in your skimmer. Mix your stabilizer in a bucket of warm water and slowly pour it into the pool. It is ideal to pour the stabilizer into your skimmer box so that it spreads throughout the pool.

What happens if stabilizer is too low in a pool?

Your chlorine can quickly dissipate and disappear if the conditioner or stabilizer in your pool runs low. The cyanuric acid in pool stabilizer makes your chlorine last longer so it can effectively kill contaminants. This can cause algae and bacteria accumulation and swimmers can experience waterborne illnesses.

Does pool shock kill algae?

Pool shock can kill algae if you apply it consistently over 1-3 days. It is more effective if you scrub the walls and floor with a brush or vacuum the pool. Use algaecide and chlorine together to kill algae and prevent it from coming back.
