500 gallon galvanized stock stank, above ground, on concrete, with a fishmate filter box to agitate the water to keep an air hole open (worked in keeping hole in ice in a 3' above ground pool/pond (1700 gallons) and fish survived for many years, but was on dirt and not cement...
Everyone is telling me that 2 feet will freeze solid when 3 feet did not...the fish mate did a good job in keeping a air hole open...
if I add a 1500 watt sinking de-icer heater, will that be enough to keep enough water from freezing?
