Meta: Are you experiencing skin irritation while in your swimming pool? Is your pool experiencing a high level of alkalinity? It’s possibly due to alkalinity. Here are…
Although high-level alkalinity doesn’t cause lots of damage to your swimming pool surfaces and equipment as low alkalinity, alkalinity level needs to remain balanced in order to reduce any unforeseen maintenance costs that might occur due to wear and tear of apparatus. Again, your skin might get irritated while swimming in a facility that has a high level of alkalinity.
These are the exert scenarios that I used to find myself in until I decided to learn how to lower alkalinity in pool. With that said, let me share with you want I learned.
Things You Will Require
You might need to visit your local store to get some of these things.
- A Lamotte or Taylor Total Alkalinity Testing Kit
- Muriatic Acid or Diluted Sulfuric Acid
- A face mask
- A Spa Jet or a Spay Nozzle and a Garden Hose
Step by Step Instructions
Here are the five steps that you will need to follow to lower the alkalinity in your pool.
1. Prepare the things you will require
How do you prepare these things?
A Lamotte or Taylor Total Alkalinity Testing Kit
Your kit should be drop-based because it’s known to offer more precise readings. If you cannot get any of these brands, you may go for other Total alkalinity or Carbonate alkalinity testing kits.
You shouldn’t consider buying Strip Alkalinity tests unless you don’t have an alternative. There are some people who will recommend you these kits but I must warn you that these individuals want you to think that your pool alkalinity is off and thus seek their services or buy their product.
Muriatic acid is used to reduce the pH of your pool. You should use it properly and always remember that it usually burn the skin and might irritate your eyes (when it’s highly concentrated). Always use goggles, a face mask, and gloves when handling this acid.
If you don’t have Muriatic acid, you may use dry acid or diluted sulfuric acid, also called sodium bisulfate. However, you shouldn’t use sodium bisulfate on pools made from concrete or plaster.
A Spa Jet
This jet is used to aerate your swimming pool naturally. If you don’t own a spa jet, you may connect a spray nozzle to a garden hose so you may slowly fill your pool while forming bubbles on the base and surface of the water.
Alternatively, you may play in your pool and splash water but don’t try this after adding the acid.
2. Test the alkalinity of your pool
The second thing is to determine the alkalinity of your pool using the testing kit. Your pool needs to have a figure of around 80-120 ppm (parts per million). Don’t lower your pool’s alkalinity unnecessarily, instead, always aim for about 100 ppm – you will be on the safe side.
You may also reduce the pH if you wish to avoid scaling and ensure that it will not rise up too fast. Remember that there is no recommended number when it comes to a swimming pool alkalinity level.
3. Use muriatic acid to lower the alkalinity (or sulfuric acid)
To avoid harming yourself, ensure that you wear protective gear before you open this acid. Additionally, ensure that you open and store it away from kids or pets so as to avoid spilling by accident. Also, remember that muriatic acid may cause serious injuries, damage, and even death.
Turn off your swimming pool and ensure that the water is totally still before you add the acid. Next, find out how much of this acid you will need to use by determining your desired ppm value and determining how many gallons of water your swimming pool holds or has.
Most products, including muriatic acid, will have a table that shows how many pounds of acid will be required to reduce the alkalinity by 10ppm to 100 ppm. Generally, a 20,000 gallons pool requires 4.3 pounds of acid to reduce its alkalinity by 10 ppm. Of important, always follow the product’s instructions.
Finally, always pour the acid into the deepest end using a stable stream that will go down to the base of your swimming pool. After one to two hours, you may turn the pump on to assist circulate the acid. Check your pool’s alkalinity level again after six hours. Remember that it might take a few days before you notice any change.
4. Aerate your swimming pool
Aerating the water in your swimming pool might actually help you reduce the alkaline level of your pool water by its own (it’s a great way to lower the alkalinity of your pool naturally). However, it will take weeks, if not months, if you don’t use the acid.
On the other hand, waiting for the acid to take its course will also take a lot of time. This is why I recommend that you use both the acid and aeration to complement each other.
Use a spa jet to aerate your swimming pool water or even use a spray nozzle attached to a garden hose to form bubbles on the surface of your swimming pool water.
5. Recheck the alkalinity of your swimming pool
Before you switch off the aerator, you should recheck the alkalinity level of your facility first. If you have achieved the desired level, you should turn your aerator off. But if not, add more acid and wait for a few hours (I wait for 3 days) before you enter your pool again. Ensure that you notify your family and friends after adding the acid. You can even leave a sign on the entrance.
Maintaining the ideal level of alkalinity in your swimming pool is one of the most important water balancing procedures. As a swimming pool owner, you need to be able to determine the alkalinity and know how to lower alkalinity in pool. You should also understand what chemicals you should use to lower this alkalinity.
