What pool chemicals do I really need?

Author: Alexander Halvorson  |  Last update: Thursday, April 7, 2022

To maintain a safe and healthy swimming pool, you need to keep your pool chemicals at the following levels:
  • pH: 7.4 to 7.6.
  • Alkalinity: 100 to 150 ppm.
  • Calcium Hardness: 175 to 225 ppm and 225 to 275 ppm for plaster pools.
  • For Chlorine or Salt Water Pools: 1 to 3 ppm (I recommend you keep it at 3 ppm)

What is the most important chemical for a pool?

Chlorine. The most popular pool sanitizer due to its efficacy and low cost, chlorine sanitizes your pool by oxidizing contaminants. It enters molecules and destroys them from the inside out. Chlorine is effective at killing viruses, bacteria, and algae, and will also help prevent algae from growing in the first place.

What chemicals do you need to start up a pool?

Chemicals Needed for Pool Start Ups
  • Stain & Scale Preventer.
  • Granular Shock Chlorine.
  • Chlorine Tablets.
  • pH Increaser and/or pH Decreaser.
  • Alkalinity and/or Calcium Increaser.
  • Cyanuric Acid (Stabilizer)
  • Algaecide and Clarifiers if needed.
  • Complete Test Kit or Test Strips.

Should I shock my pool when I first fill it up?

At first you'll add chlorine in what's called “shock” levels – an extra heavy dose to start your pool off. A shock dose coupled with extra circulation will ensure that all the water gets treated properly in the beginning.

How much chlorine do I add to my pool for the first time?

If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water – while the pool filter is running. This should give you a chlorine level of about 3 ppm.

What is proper pool chemistry?

A pool that is "balanced" has proper levels of pH, Total Alkalinity, and Calcium Hardness. These are: pH: 7.2-7.8, Total Alkalinity: 80-120 ppm, Calcium Hardness, 180-220 ppm and Cyanuric Acid (Stabilizer): 30-50 ppm. Chlorine levels should remain constant in the 1-3 ppm range.

Do Bestway Pools need chlorine?

Like water in any other swimming pool, a Bestway pool's water has to be consistently sanitized. For chemical water disinfection, you can use either chlorine or bromine in a Bestway aboveground pool. Maintain Bestway aboveground pool chlorine levels at 1 to 3 parts per million (ppm) or bromine levels at 2 to 4 ppm.

What eats chlorine in a pool?

The chlorine in your pool acts the same way. Keep in mind, organic materials like algae, leaves, sunscreen, lotions, pee, poop, and etc., consume chlorine. As chlorine does its job, it is depleted in the process.

Why is my pool going through chlorine so fast?

Chlorine lock can occur when there is too much cyanuric acid (also referred to as conditioner or stabilizer) in the water. This occurs when too much stabilizer is added to the water or when the swimming pool isn't being partially drained and refilled periodically. Chlorine lock can also occur if the pH is unbalanced.

Why is my pool going through so much chlorine?

One of the causes of a high chlorine demand is an excessive buildup of algae and phosphates. Although you're adding chlorine to your water, bacteria or algae are overpowering the chemicals causing it not to show up on tests strips or in water kits.

Can you swim in a pool with low chlorine?

The Bottom Line about Pools and Chlorine

As mentioned above, you could probably swim in a pool without chlorine without any major health issues. However, long-term use of a pool lacking chlorinated H2O could make you sick or, at the very least, contribute to rashes and other types of skin irritation.

Can I just throw chlorine tablets in my pool?

NEVER just throw them into your pool water. This will cause them to dissolve on the floor and it can damage and create a permanent bleach stain to your liner or concrete.

Should I put chemicals in my Bestway pool?

Chlorine is used to disinfect the pool water and keep it free from bacteria so it's safe to swim in. For Bestway pools, it's recommended you use either a chlorine or bromine water sanitiser over non-chlorine alternatives.

How often should I add chlorine to my pool?

Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.

Can you swim 10 chlorine ppm?

What chlorine level is too high to swim? It depends on who you ask, but the acceptable range is between 1 to 5 ppm. (So, for example, 10 ppm chlorine is not safe to swim in — that's too high.)

Will liquid chlorine raise pH?

Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.

What should my salt water pool levels be?

The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level.

How many chlorine tablets do I need for a 10ft pool?

Do i fill the whole thing up till filled with tablets? or do i stick one tablet in for a 10ft summer wave pool. thanks:-) Answer: One tablet is all you need.

What chemicals do I need for my above ground pool?

Things you'll be testing for include chlorine, PH, total alkalinity, Cyanuric acid (stabilizer), and calcium hardness. The levels need to be properly balanced for safe and clean water before swimming in it. The free chlorine level should be between 2.0 and 4.0 ppm. The PH level should be between 7.2 and 7.8.

How often should I shock my pool?

How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.

Is it better to put chlorine tablets in skimmer or floater?

While a floater does not distribute chlorine as evenly as an in-line chlorinator, it is still a great form of swimming pool chlorination. Never put chlorine tablets into the skimmer baskets of your pool. Some pool companies will put chlorine tablets directly into the skimmer baskets of the pool.

Do you need a chlorine floater?

Chlorine tablets are slow dissolving and therefore need to be placed in either a floating dispenser, in-line chlorine feeder or a skimmer basket.

What happens if you don't put chemicals in your pool?

Even from a health standpoint, it is simply not safe to operate a pool without some added “chemicals” to combat bacteria and contaminants in the water. A pool without chemicals is the perfect breeding ground for bacteria, viruses, and parasites.

How do you know if your pool is safe to swim in?

As a backyard pool owner, you should check the disinfectant (chlorine or bromine) level and pH at least twice per day (and more often when the pool is in heavy use) to make sure they are correct: 1–10 parts per million (ppm) free chlorine or 3–8 ppm bromine. pH 7.2–7.8.
