Care of your HX gas heater:

• By far, the most important thing is Water Balance. Corrosion from low-pH & High Bromine / Chlorine is the biggest killer of gas heaters. The water can look Crystal Clear & Perfect, while it's eating away at at the Copper heat exchanger fittings. Bromine, Trichlor Tablets, and Dichlor powders lower water pH.
