Re: [APD] Microwaving water for water changes a bad thing?



For many years all water heaters in this country have been glass lined, and if the lining were to break, the heater would soon rust through and leak. But, I do recall that some water heaters have sacrificial electrodes, probably zinc, in them to protect from electrolysis. Is zinc harmful to plants or fish?
