Description
BioGuard Lo N Slo reduces pH and total alkalinity in pool water. This product is generally easier to use and store than liquid muriatic acid. Keeping your pool's pH level balanced is not only important for swimmer comfort; it also helps keep your equipment and pool finish in good condition. Swimmers may return to the pool only 15 minutes after application. You can slowly and safely reduce pH and total alkalinity with Lo N Slo.
Testing Pool pH:Test your pools pH level regularly (ideally twice per week) with a test kit or test strips. In addition, we recommend periodically (once per month) taking a water sample to a dealer test station to verify the results.
One of the biggest parts of pool care is maintaining the chemical balance in your pool. Pool chemistry is not only necessary to keep your pool clean and safe, maintaining a proper pH level in your pool is essential in order for other chemicals to do their work. Chlorine is much less effective at higher pH levels; in fact, at a pH of 8.2, chlorine is only 15% effective. The optimal pH range for your pool is 7.2-7.8. Is your swimming pool well balanced?
High pH
When your pool has a high pH level, it means the water is basic and over time high pH levels can cause the water to scale on your pool filters, plugs, pipes and other equipment. Water scale can reduce the water circulation, thus increasing water pressure within the circulation system and putting strain on your pool equipment.
Why is my pools pH high?
Below are a few reasons why your pools pH level may be a bit high:
- Local water source may have a higher than normal pH level
- You might have added a little too much pH increaser when you saw your pools pH level was low
- Adding Liquid Chlorine
- Pools with a Salt Water Chlorination system typically tend to have high pH
How to lower your pools pH
First test your pools pH level, to help you determine the best type of chemical to use to lower your pools pH.
There are two main chemicals typically used to decrease pH in pools, muriatic acid and dry acid (also known as Lo & Slo or ph Decreaser). Although they are designed to do the same thing, pay attention to which chemical you are using, because how you add the chemical differs.
Low pH
A low pH level means your pool water is acidic, which can not only cause corrosion of pool surfaces and equipment, it can also reduce your ability to control total alkalinity and cause an uncomfortable swimming experience for your family and guests, as acidic water will sting eyes and remove the natural oils on skin, leaving it dry and itchy.
Why is my pools pH low?
Many things can lower the pH in your swimming pool:
- You might have added too much pH reducer in an attempt to lower the pH of your swimming pool
- Your local water source may have a low pH, this may be the culprit if you are continually having to add pH increasing chemicals
- Heavy pool usage can introduce a large amount of natural contaminants (i.e. saliva, body oils, sweat, etc). All of these natural contaminants can lower the pH level in your pool.
- Organic matter such as grass, insects and dust are common organic matter that can lower the pH
- Rain picks up impurities in the air as it falls, raising the acidity, thus lowering your pools pH
- Shocking your pool can lower the pH depending on the type of shock.
How to raise your pools pH
Increase the pH in your swimming pool using Balance Pak 200 or pH Increaser. Once you’ve added the pH Increaser, you’ll want to wait at least 6 hours before retesting your pools pH level.
