  “David M. is the guy!  If you need a “go to pool guy” to answer pool chemistry questions call David.  I have a 25.000 gallon in-ground pool(reason we purchased the house 5 years ago). Every year has been a challenge to open the pool.  We are on a well with lots of Iron and other metals.  Every year I would go to the local pool store and ask for advice on how to open my pool.  Every year I would end up spending hundreds of dollars on chemicals that they said would give me sparkling clear pool water.  Every year it would take a month or more just to get the pool to a swimmable state.  I would get the pool balanced and then they would say add more chlorine(more money).  One year after shocking the pool(just add more they said) my pool water turned a very pretty purplish brown! Unswimmable!  I looked online for help and I stumbled across the Periodic Products website.  I called them up and spoke with David.  I explained what was going on with my pool and he said stop.  He explained what was going on chemistry wise with my pool water.  He than laid out a plan step by step to get my pool water to that beautiful crystal clear state.  David said do this today and call me tomorrow and let me know what happened.  He did this over and over again until I had crystal clear pool water.  The amazing thing about his advice was every time he said to do something I got the exact result he said I would get.  It was as if he was at my house performing the task himself!  Another amazing thing was he didn’t try to sell me anything!  The only thing I purchased from David was  a CuLator 4.0 pack.  This I needed to eliminate the metals in my pool water from my well.  David gave me hundreds of dollars worth of advice and information free of charge and he did so with so much joy.  His advice gave me joy because it worked but it seemed to give him even greater joy because he had helped me. Again David is the guy!  I can’t say that enough or with enough enthusiasm!  I am now enjoying my pool(the reason we bought the house).  Thank You David and Periodic Products.   Marshall Washington State Pool owner

Why does the CuLator Ultra 4.0 Swell Up?

Holding CuLator Ultra 4.0 Up To The Light
When CuLator is added to the skimmer or pump basket, it usually swells up and becomes very puffy. This is normal. The best way to see if the CuLator is catching metals is to hold it up to the light. In this case, there is some blue at the top showing that the CuLator is binding copper out of the swimming pool water and preventing stains.

 

Why does the CuLator Ultra 4.0 puff up? The CuLator polymers “hydrate” when they enter the water and puff up.  As they bind the metals out of the pool water, the CuLator bags will “shrink” back down to a much smaller size.  So, when is CuLator finished?  It is easier to tell with the Ultra 4.0 because the bag will be about 1/2 full, or the contents will feel watery inside or they will feel sandy.  With the 1.0 it is a little bit harder to tell, but when the bag feels almost empty or there is a lot of color in the bag after a month, then it is exhausted.
