I am a very sceptical person by nature and have never heard of this type of product. I found this website and looked at others and decided to purchase the water tank tec one. I installed this product on a new AO 40 gallon tank.

The anode was hell to remove but I won.

This was 2 months ago and I feel positive about writing a review and about the product. Not sure how they work but when I installed this product the anode was getting 1.2 volts and I figured it was a dud land was pissed. 2 days later I checked it and the voltage was 2.7 volts. Checked it new years day, 2.6 volts. I really think what their add says is true. It adjusts. Great product.
