A simple ratio and a standard rule of thumb to follow when you shock your pool is to dissolve one pound of either calcium hypochlorite or sodium dichlor for every 10,000 gallons of pool water. If you are using sodium hypochlorite, i.e., liquid chlorine, the ratio comes out to 10 ounces for every 10,000 gallons of pool water.

The equation for this measurement is L x W x D x 7.5 = V. The calculation you use will differ if your pool has a gradual slope. The depth of the shallow end needs to be added to the depth of the deep end, after which the number should be divided by two. This number equals the average depth of your pool.Apr 6, 2021

What chemicals should I balance first in my pool?

Total AlkalinityTotal Alkalinity (TA) is the first thing you should balance in your pool water. TA refers to the amount of alkaline material in the water. And since alkaline is a pH stabilizer, the number of alkaline substances in water will affect the pH balance. The ideal Total Alkalinity range for pool water is 80 – 120 ppm.

Do I add chlorine or stabilizer first?

Add Stabilizer (Cyanuric Acid) Stabilizer is cyanuric acid. It's important that you get this right BEFORE adjusting the chlorine levels. The right level of stabilizer basically makes the chlorine you add more effective and helps it last longer.

How do you calculate chlorine?

Divide the daily chlorine input by the MGD flow of the facility. In the example, the result would yield 33.33. Divide the result by 8.34 pounds per gallon to find the chlorine concentration. In the example, the concentration is 4 milligrams per liter.

How do you calculate total chlorine?

Total Chlorine is the sum of free chlorine and combined chlorine. Therefore combined chlorine is the difference between total chlorine and free chlorine. CC = TC – FC. The first step in determining the necessity of a shock treatment is to determine the level of combined chlorine.

4 poundsIn this case, you should double shock your swimming pool water. To double shock, you will need to add 2 pounds for every 10,000 gallons of water. For instance, if you pool is 20,000 gallons, you will add 4 pounds of shock.

How much shock do I need for a 10000 gallon pool?

The general recommendation is to use 1 pound of cal hypo shock for every 10,000 gallons of pool water, and 10 ounces of sodium hypo with around 12.5% chlorine to sanitize your pool. Make sure the pool water is at its normal level. Make sure your pool's pH is between 7.2–7.6 and its alkalinity is between 80–120 ppm.

Can you put too much shock in a pool?

Can you put too much shock in a pool? SKIMMER NOTES: It's unlikely but it could happen. It would take a lot of shock to really make the water unsafe for swimming. The best way to make sure you're safe to swim is to test your pool water and make sure free chlorine levels are between 1-4ppm for healthy swimming.

Pool Volume Calculation Basics

If you want to properly measure the volume of your pool, there are numerous elements that you’ll need to be aware of. These elements include:

Different Types of Chlorine

To fully understand the types of chemicals that you should place in your pool, it’s important that you know about the different types of chlorine. Free chlorine is the total amount of chlorine that hasn’t combined with the chlorinated water in order to sanitize contaminants.

Pool Calculators

While you can find many effective pool calculators on the internet, three tools that are easy to use and can help you accurately calculate your pool dimensions include:

Why do we shock pools?

It creates dangerous levels of something called Chloramines / Combined Chlorine. We shock our pools to kill Chloramines. Few understand the importance of properly shocking a pool. Most people think shock is a special chemical called shock.

How often should I check my alkalinity?

Once you get alkalinity in range, check it once a month. While NSPF water quality standards say that a range of 60-180 is acceptable for alkalinity, I have always tried to keep it between 80 and 120, with 100 being ideal. Chemicals used to raise and or lower alkalinity: To raise alkalinity we use Sodium Bicarbonate.

Can chlorine shock a pool?

NOTE: You use Chlorine to shock a pool. To figure out if you need to shock your pool, or in order to properly shock a pool / reach Breakpoint Superchlorination. You have to first figure out the level of Chloramines. This is done for you by using our calculator.

Can you mix chlorine?

Some are liquids, like Sodium Hypochlorite, Some are powders, like Trichlor, Dichlor, and Calcium Hypochlorite. NEVER MIX TYPES. If you pour liquid over solid it could go boom.

Testing Your Pool Water. You can not properly adjust your water chemistry unless you know where your at. So you need to test your water. There is a quick, simple, easy, and cheap way to test your water. I recommend Aquachek’s #7 Dipping Strips.

Does trichlor erosion tablet contain CYA?

Dichlor and Trichlor erosion tablets contain CYA, if CYA levels creep up, you may want to switch to a Calcium Hyperchlorite. The only way to reduce CYA is with water replacement. It should be noted that the higher the CYA levels, the less effective your Chlorine sanitizer is.

How to raise pH in pool?

To raise pH in pool use washing soda, dosa ash or Borax. Aerating the water will also raise pH in pool water. If the pool has a fountain or water feature, it can be run to raise the pool water pH. Use chemical reagents or test strips to find the current pH. pH Up.

What is the best pH for a pool?

Pool water pH is one of the best measures of balanced water. The pH of a human tear is 7.5, so the ideal range for best swimmer comfort is between 7.4 - 7.6. But 7.2 - 7.8 is also considered an acceptable pool water range.

Why does my pool water have a high pH?

pH drift is common and is due to a number of factors impacting the pool water. Salt water systems are one of the biggest reason for pH drifting up. Liquid chlorine also causes the pH to rise when added to the pool water. These both have a negative effect on the chlorine making the newly added chlorine less effective.

Can a high pH in a pool get you down?

Don't let a high pH in pool get you down. Oxygen Pools chlorine free pool water treatment eliminates the negative effects pH has on chlorine by not using chlorine. The Oxygen Pools Program uses two components: A Dynamic Oxygen Generator and a weekly dose of the nontoxic, non-chlorine additive.

How often should you add borate to a pool?

Borate is only lowered by water loss – splash out, drag out, leaks, and filter backwashing , or draining. So, you add it once , and unless you are losing a lot of water, you don’t need to add it again until you drain the pool and refill it.

What is the recommended free chlorine level for 50 ppm borate?

You will be using 33% to 50% less chlorine. With 50 ppm borate, the recommended free chlorine level is 5% of CYA instead of 7.5%. You will be using less acid because the pH will not be going up as much.

What is the formula for a borate ion?

Boric acid, formula B (OH)3 or H3BO3, is technically a Lewis acid. It does not release a hydrogen ion (H+) like most acids, but it can acquire an OH– from the water according to this equation: B (OH)3 + H2O ↔ B (OH)4- + H +. Boric acid plus water yields borate ion plus hydrogen ion.

How much HCl to add to Borax?

Second, to offset the high pH of the Borax you will need to add muriatic acid (31.45% HCl). The amount needed is 3 gallons for 10 boxes of Borax or 2 fl oz of muriatic acid for each 1 oz of Borax added. In addition, before adding the Borax, the alkalinity should be about 80 ppm and the pH should be about 7.4 or less.

Can you add boric acid to pool water?

Boric acid is a weak acid and has a pH of 3.8-4.8. It will not lower pool water pH by much. Most of the time the pH drop is only about 0.2 for a 50 ppm dose. Therefore, you can add boric acid without having to add muriatic acid like when adding Borax or sodium tetraborate pentahydrate.
