S For Testing Pool Water
There are various methods for testing pool water that you can choose from. These methods include:
Liquid testing kits have all the basic things you need to do regular pool water testing. When used correctly, the results are accurate. Nevertheless, this also means that you will get an inaccurate result if you make a mistake. You have to be careful since it can be difficult to use.
This kit includes 2 things the OTO or Orthotolidine for testing chlorine and phenol red for testing the pH. You also need a blank white paper sheet on hand.
After you get your pool water sample using the containers from the kit, follow the steps below:
- Put the right number of drops of OTO on the chlorine part.
- Put the right number of drops of phenol red on the pH part.
- Place the white paper sheet behind the test kit so that you can see the colors clearly.
There are higher pH levels if the pH part is higher and there is higher chlorine content if the chlorine part is yellower. You can also use the chart to compare the colors to know the levels.
Testing strips are accurate and you get all the results you need with a single strip. They are also cheaper and easier to use. However, the steps of doing the test can be complicated. The basics are provided by testing strips which are chlorine, pH, and alkalinity. There are also strips made for testing salt, copper, bromine, and iron.
After obtaining your pool water sample, here are the things you need to do:
The Tools For Testing Pool Water
What do you use to test the pool water chemistry?
- Test strips
- Liquid testing kits
- Digital pool testers
You can dip litmus test strips into the water and compare the color to the chartits fast, simple, and inexpensive. However, this method is the least accurate option.
Liquid testing kits provide more accurate and more thorough results. Their price does rise accordingly.
Digital pool testers sometimes look like thermometers. They provide the fastest and most accurate results because theyre, well, digital. No human interpretation required. Theyre also the best option for pool owners who have trouble distinguishing colors. For obvious reasons, though, they are the most expensive method for pool testing.

How To Maintain Proper Ph
It is important that you monitor your pools pH level daily using test strips. To test your water, go to an area away from the skimmer and the returns and follow the instructions on the package. Remove the strip from the water but dont shake excess water off. Wait for the colors to fill in, then compare the strip to the color range on the product container.
Adjusting the pH is then a matter of using pH increasers or pH decreasers . The amounts needed will, of course, be based on how far out of balance your water is and the volume of water in your pool. Follow the instructions on the product packaging.

How Frequently Should I Test My Swimming Pool Water
Different chemicals need to be tested at different frequencies, based on how much they can fluctuate and their importance to the overall health of the pool. The main three tests as mentioned above chlorine, pH and alkalinity should be tested at least once a week during use, with the other checks occurring monthly.
At 1st Direct Pools, we always recommend people conduct these tests daily, to ensure the chemicals in the water are at a safe level.
All necessary tests should be made when opening your pool for the first time after a prolonged closure, such as during the winter. Furthermore, all tests should be completed before closing your pool.
As all swimming pools are different, the test frequency should be adjusted to suit your needs. Speak to a professional who might recommend another particular test that your pool should take more frequently. Also, when the pool is in frequent use, such as during the summer, it is recommended that these tests happen more regularly.
What Do I Test The Pool Water For
As a pool owner, youll keep track of 5 main areas:
pH is how we measure how acidic or basic/alkaline the pool water is.
The scale ranges from 1 to 14 . Pure water is right in the middle, at 7.
Why is incorrect pH bad for your pool?
Whether too high or too low, improper pH levels can damage your pool and its equipment.

When To Test Your Pool More Often
You may need to test your pool water more often depending on how much you swim, who uses the pool and what the weather is like. When youre going for a dip or swimming laps more than once a day, measure the free chlorine four to five times each week.
If pets or little kids use your pool, you should also be testing the free chlorine four or five times each week. Pets and kids are more likely to go to the bathroom in the pool, which affects the chemical levels greatly.
Having a pool party? Test the pool water before your guests arrive and after they leave. The more people who use the pool, the more the chemical balance will be affected. Taking measurements prior to the party and afterward will help you see exactly how the numbers change.
When it rains, a lot of fresh water can end up in your pool, which can make the water more acidic. After a storm passes, test your pool waters free chlorine and pH as soon as possible.
Regular pool water testing lets you know which chemicals need to be adjusted. Keeping the right chemical balance may require you to check your pool water as often as every few days.

The Order For Testing Pool Water
Whatever tool you choose, test the pool water every week.
Each level affects the others, so if you test and adjust water chemistry levels out of order, you’ll have to backtrack and fix the levels multiple times.
Save yourself time and effort by following this order:
Each pool typeconcrete, vinyl liner, and fiberglasshas its own pros and cons.
Concrete pools look classic but are the most difficult type of pool to maintain because of how alkaline and porous the surface is. The water chemistry can easily get out of whack, and algae sets in. They also require acid washing every 35 years, resurfacing every 1015 years, and a professional cleaning each season.
Vinyl liner pools don’t have so much trouble with the water chemistry, but they have a different set of issues: you need to replace the liner every 59 years.
The gelcoat surface of a fiberglass pool is inert: it doesnt affect the water pH. You still need to test your water chemistry each week, but youll rarely need to add acid to balance the water. And as long as the pool is well manufactured and well maintained, there won’t be any required maintenance to the pool shell for many decades.
Of all 3 pool types, fiberglass pools require the least maintenance over the life of the pool. They cost $45,000$85,000 upfront, but they have incredibly low lifetime expenses, which saves you money in the long run.

Testing For Ph Balance In Your Pool Water
The pH scale is a reading of how acid or alkaline the water in your pool is.
The pH scale goes from 0 to 14 with 7 being neutral. A reading of below 7 indicates that your pool water is acidic while levels above that are defined as alkaline.
You want the water in your pool to have a pH reading of between 7.2 and 7.8 and you have to test and possibly adjust the pH reading of your pool water on a regular basis as everything that goes into your pool has a pH value and so will alter the pH reading to some degree.
You test the water with a simple kit that you can get from your pool supplier.
Using the measured container that comes with the kit you take a sample of water from a foot or so below the surface and then add an indicator solution and compare the colour change to a chart that gives an equivalent pH reading.
If your pool water tests below 7.2 the water is acidic and you should add an alkaline commonly sodium carbonate, and if the level is too high then muriatic acid needs to be added to restore the balance.
You should test the water once a week as, if the pool is too acidic then the chlorine that you are using as a sanitiser will be lost to the atmosphere and need to be replaced too often plus you run the risk of corrosion on metal parts and equipment.
If the pH is too high, showing that the pool is too alkaline then the water may become cloudy and murky and, once again, the chlorine sanitiser will not be working effectively.
How To Fix High Salt Levels
To prevent your chlorinator from having to work too hard to assimilate an overabundance of salt, its a good idea to reduce too-high salt levels. You can easily accomplish this by draining a few inches of water from your pool, and adding fresh water to bring the level back up.
Retest, and continue the process until salt levels are back in the optimal range.

Testing Based On Pool Usage And Other Factors
- When re-opening the pool: Because your pool has likely been left unattended for the better part of the year, always run water quality tests before commencing use.
- After storms or major weather events: Always test after a major weather event. Increased rainfall, for example, can throw off the chlorine and pH balance of a pool.
- After frequent use: If you use your pool more than once a day, check chlorine levels around four to five days per week to daily, at least.
- Before and after usage by children, pets or large groups: Contaminants that disrupt the delicate chemical balance of your pool are easily introduced.
