Simply put it determines whether your pool is acid or alkaline base.
High ph in vinyl pool.
The bold numbers in the middle of the table show the most common carbonate alkalinity ranges in swimming pools.
The water may also have cloudiness issues.
Don t forget your ph test is going to read a false high with fc at 10 or above.
This is important because when ph gets over 8 2 it becomes much more difficult for calcium carbonate to stay in solution the lsi is too high usually.
Let us explain to you how this is possible what the consequences are and how it can be solved.
That would be a target of 7 8 and never below 4.
Water s ph level is just a measure of total acid alkalinity balance.
If you have a smaller pool or an above ground pool you would start with one cup of acid and then re test and add more if needed.
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.
The total alkalinity should be between 80 ppm and 150 ppm.
While this may sound very pleasant the consequences are anything but.
This idealrange is considered balanced for pool water even though this range is technically on the basicside of the scale.
If ph is too high you can see scaling and calcium deposits on your pool and perhaps algae problems.
Throw in a dry acid such as sodium bisulfate.
If the level becomes too high here s how to lower the ph in a pool.
Match the amount of dry acid you add based on the ph reading.
When water is too alkaline it reduces the effectiveness of the chlorine the pool chemical that kills pathogens.
The ph level should be between 7 2 and 7 6.
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.
If the ph gets higher than 7 8 the water is becoming too alkaline.
Recommendations for ph in a vinyl liner pool ph should be between the range of 7 2 7 6.
Less than 7 4 is acidic more than 7 6 is more basic.
A couple of days ago your cya level was 60.
A too high ph level in your pool is a ph value that exceeds 7 6 ph.
Chart values are for 77ºf water.
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.
It s important to remember that ph can measure anywhere from 1 to 14 but pool s ideal ranges are 7 2 7 6.
Keep letting your fc drift down to maintenance level s.
Test your water s ph and total alkalinity using a pool water testing kit.
