sweet effects.  Not sure if you remember us, but we ordered some Crystal Clean a while back. We used it for a few months with no success. It turns out we owe you a huge apology. We took your advice in your last e-mail and had someone come out and check our water.   We discovered that the bypass for the water softener was on the whole time, so we were using raw well water the whole time. I’m so sorry. We moved to the country and I was not familiar about how the system worked, so I didn’t realize that the water wasn’t even going through the softener. We sent the pump back to you and got a refund no problem. I have been adding the remainder of the solution that we have manually to the brine tank, and there has been no smell and the rust has virtually vanished! Recently, I stopped adding it in the tank and the smell has started to come back. So the short of it is, I guess it would have worked great for us. I was wondering if we paid for the initial cost that was refunded to us and got you to send us the pump back plus some more Crystal Clean.
