powdered shock/chlorine tabs never completely dissolve

Postby mystic » Mon 24 Jul, 2006 21:08

For years i have had the same problems with powdered chlorines and shock. the stuff does not dissolve properly. Powdered shock just never dissolves...I have turned to liquid shock to solve this. But, I can't help but wonder why this is. Also, my chlorine tabs never completely melt. I end up throwing them away and adding new ones which only half dissolve. Pool water tests out okay for PH and I keep the chlorine level up to where it should be. Why won't my powdered chlorine dissolve properly?

How is your alkalinity and stabiliser? These are important factors on how quickly your chlorine gets used up (or not used up) in your pool?

If you don’t have a four way test kit (CL, PH, alk, & stab) I highly suggest that you do the $10 investment. Having proper water chemistry will save you so much grief in the long run.

Hope that’s fixed the problem!

It may be precipitating out of solution because of high pH and/or high alcalinity.

Does it not dissolve in the pool or in a bucket when you premix?

If it is in the bucket, there is just not enough water for the product to be fully absorbed.
In the pool, it should eventually dissolve. Water temperature plays a large part of dissolution/
