It's muriatic. I would add chlorine only at start up & acid only when it's needed. Your supplier can show you how to check the pH & determine when one or the other is needed.

How do you keep chlorine in pool?

Chlorine is effected by sun, air, temp and bather load. You should check first to see that your stabalizer (cyanuric acid) level is ok, 30-50 ppm. That will help chlorine stay in water.


Should you be using stabilized Chlorine in your pool everyday or is the Granular better?

Use stabilized chlorine only so long as stabilizer level (cyanuric acid level) in pool is within the recommended range of 50-80ppm.


How often should the water be changed in 3700-gallon above-ground pool?

Assuming no other complaints you would only need to change water to lower the total dissolved solids level or cyanuric acid level. TDS should be below 500ppm and cyanuric acid ~50 ppm.

You have low chlorine level in above ground pool?

If you are getting a low reading of chlorine in your above ground pool, you should add the appropriate amount of chlorine to get it back to the correct level. This is important to keep your pool running at maximum abilities.


What effects a pool to loose its status of chlorine?

Chlorine is taken up by biomaterials for one. that is the more dirt there is in the pool even stuff you cant see the more chlorine seems to disapear. the sun and the activitys of swimmers also have a big effect on chlorine consumotion. to hold onto the chlorine longer, Conditioner or Cyanuric Acid Levels should be kept up to about 80ppm, Low conditioner levels will lead to a lot of the chlorine in the water being burned of without it being utilized.


What is cyan uric acid in pool water?

The constant use of small 1" , large 3" jumbo chlorine tabs and granular chlorine. they all have cyanurics acid in the compound mix. Best to switch to liquid for a while ( a month of so). The high levels of cyanurics will eventually drop as water evaporates and you add fill water. High levels of cyanuric acid or conditioner would be considered to be in excess of 100 ppm. You could also do a partial drain of the pool and refill to reduce the CYA faster. In the future you might consider alternating between liquid 12% chlorine and tabs. Note: 1" tabs dissolve faster. HTH granular and tabs I believe do not contain conditioner but then it is a lesser grade of chlorine - see percentage values on label.


What should be the startup type of service that should not load at startup but might be used later after startup?

Manual Startup. Use services.msc in command prompt to set the startup.


How often should an in ground pool be drained and given a chlorine bath?

I cant see why it should be drained and given a chlorine bath at all. If there is no problem with the water or the looks of the pool leave it alone.
