The bold numbers in the middle of the table show the most common carbonate alkalinity ranges in swimming pools.
High ph in vinyl pool.
This idealrange is considered balanced for pool water even though this range is technically on the basicside of the scale.
Keep letting your fc drift down to maintenance level s.
When water is too alkaline it reduces the effectiveness of the chlorine the pool chemical that kills pathogens.
If you have a ph reading of 7 8 or higher and an average size 15 000 gallons in ground pool you should add 1 4 gallon a quart of muriatic acid and re test after the water has circulated for an hour.
If ph is too high you can see scaling and calcium deposits on your pool and perhaps algae problems.
A too high ph level in your pool is a ph value that exceeds 7 6 ph.
The water may also have cloudiness issues.
Throw in a dry acid such as sodium bisulfate.
Less than 7 4 is acidic more than 7 6 is more basic.
Recommendations for ph in a vinyl liner pool ph should be between the range of 7 2 7 6.
Match the amount of dry acid you add based on the ph reading.
That would be a target of 7 8 and never below 4.
While this may sound very pleasant the consequences are anything but.
Chart values are for 77ºf water.
Ph is used to measure the acidityof your swimming pool and you need to maintain this ph level consistently within a ph range of 7 4 7 6.
A couple of days ago your cya level was 60.
Let us explain to you how this is possible what the consequences are and how it can be solved.
If the level becomes too high here s how to lower the ph in a pool.
For instance if you have a 50 000 gallon swimming pool and the ph reading is 8 0 you should throw in 900 grams of sodium bisulfate.
The ph level should be between 7 2 and 7 6.
It s important to remember that ph can measure anywhere from 1 to 14 but pool s ideal ranges are 7 2 7 6.
Proper pool ph is right in the middle pool pros recommend that ph be between 7 3 and 7 6 for optimum performance and cleanest water.
Don t forget your ph test is going to read a false high with fc at 10 or above.
Simply put it determines whether your pool is acid or alkaline base.
Test your water s ph and total alkalinity using a pool water testing kit.
The water will then be too soft.
If the levels are too high you will need to lower your water s ph.
If the ph gets higher than 7 8 the water is becoming too alkaline.
The total alkalinity should be between 80 ppm and 150 ppm.
