I gave a friend of mine a 5 gallon freshwater setup a while back and he just recently rteturned it to me. The water in his city was unbelievable hard and there are hard water deposits on the glass and heater unlike and I've seen before. I've soaked the tank in lemon water and these stains are barely budging. Does anyone know of any other mathods to remove these hard stains?
