Valdimir and Zoya

I purchased a product 8 months ago for my new tank on Amazon. It did nothing but ruin my water quality and my tank. Black debris in the faucet and the odor was atrocious, not rotten eggs but a different smell I cant describe. The company sent me a new power supply saying it would take care of the problem and it did nothing. Contacted the company again and was send another anode. When taking the old one out. The black coating on the anode was gone and showing a rusty silver metal. I was pissed since another anode is going to do the same thing but installed it anyway. The new one leaked from the top down the side of my tank and smelled like a toilet. Contacted the company again and was send a new power supply and anode which I threw away. I had to by a new tank and repair the unility room floor from the water damage. My ending, purchased this product after reading very informative website. No odor or chunks of black crap in 3 months power to the andode stays at 2.9 volts. My problem is solved and I thank the company for this and their 12 emails back to me.
