The bold numbers in the middle of the table show the most common carbonate alkalinity ranges in swimming pools.
High ph in vinyl pool.
Water s ph level is just a measure of total acid alkalinity balance.
Throw in a dry acid such as sodium bisulfate.
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 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.
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.
Recommendations for ph in a vinyl liner pool ph should be between the range of 7 2 7 6.
The ph level should be between 7 2 and 7 6.
Test your water s ph and total alkalinity using a pool water testing kit.
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.
This idealrange is considered balanced for pool water even though this range is technically on the basicside of the scale.
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.
If the levels are too high you will need to lower your water s ph.
Simply put it determines whether your pool is acid or alkaline base.
While this may sound very pleasant the consequences are anything but.
Don t forget your ph test is going to read a false high with fc at 10 or above.
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.
Less than 7 4 is acidic more than 7 6 is more basic.
If the level becomes too high here s how to lower the ph in a pool.
The water may also have cloudiness issues.
That would be a target of 7 8 and never below 4.
The water will then be too soft.
The total alkalinity should be between 80 ppm and 150 ppm.
If ph is too high you can see scaling and calcium deposits on your pool and perhaps algae problems.
Keep letting your fc drift down to maintenance level s.
If the ph gets higher than 7 8 the water is becoming too alkaline.
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.
Match the amount of dry acid you add based on the ph reading.
