Let me start out by stating that I am aware that mixing two different sequestrants is not normally a good idea. The answer to the question I am asking will likely result in a no answer but I will ask the question just in case it is yes.
I just did an Iron treatment with Ascorbic Acid and the pool looks great. Unfortunately I know that despite adding Jack's Magic Purple Stuff on a weekly maintenance schedule it will slowly but surely start to stain again. My purpose in asking the following question is to see if I can extend the time frame and have a pool that remains relatively more stain free for longer.
The stains are not from pool water but from volcanic soil dust blown over our mountain from agricultural lands behind that mountain, which contain iron, blowing in with the trade winds whose speeds average 16 mph to 24 mph.
As these two products are in many ways chemically completely different could they be mixed and thereby extend the stain free time?
I realize that there would be additional cost but it would be worth the piece of mind to see the pool with less staining.
Going forward at the present time I am using the Purple stuff based on Chem Geek's recommendation.
As mentioned I am guessing the answer is no but I am curious to know the chemical reason as to why.
