Customer Experiences

I love Sanz!

I was ready to fill in my pool. I couldn’t keep it clear. Over the years I tried cartridges, DE, and then sand. “This one is better”, “This one will work”. They didn’t.

I read about Filter Balls but the stories didn’t add up. It sounded like a lot of money that would be another failure. I was totally discouraged and really did want to fill in my beautiful pool. I had nothing else to lose so I took a chance. I am very glad that I did and I am totally grateful for Sanz. My pool was crystal clear all summer, ALL summer. It was no work at all. I even removed the skimmer socks I used to minimize filth into my filter. I had to clean those socks every single day.

Switching to Sanz was the most productive thing I ever did for this pool. I am 62 and did not think that I had the strength to keep maintaining my pool everyday, but now it requires only a fraction of the work I used to do, yet is far cleaner. I even left it for a week uncared for but when I returned it was still sparkling clear. I back washed my Filter Balls only twice all season.

I chose Sanz because we have a lot of pollen that was too small for the sand to filter and I wanted the smallest filtration to eliminate it all from my water. It did! I am grateful. I blessed you all, every day for giving me back my pool.

I have attached before and after photos. Kind Regards, CD
