This is a repeat order, have been very happy with how well this product works and how easy it is to use.

Great product fast shipping

Before using this my water heaters were burning out within a year. I have well water and found without this product my heating element would quickly build up a white scale over the entire element and eventually stop working. Since using 1 oz a week of the scale defender I haven’t replaced my heater in over 5 years. I’m sure it’s coming soon as they are normally good for about 5 years from what I hear.

Seems to work well so far been using it about a year.. and less to add then other brands

This product seems to work OK but I've noticed that, over time, a slimy residue starts to grow within the unused portion of this treatment. In other words, once I've used about half the bottle I start to see stuff floating in the chemical. It's slimy and doesn't look like something that I want to put into my hot tub. What is this? At first I thought it was just something with the particular batch/bottle I had but I see the same thing happening on subsequent bottles of this that I've purchased.
