Floating pond heaters and de-icers keep a critical ice-free opening in your pond surface during winter. This hole allows toxic gases (ammonia, hydrogen sulfide) to escape and fresh oxygen to enter — without it, fish can suffocate under the ice. Play It Koi carries thermostat-controlled floating heaters from trusted brands rated for ponds of all sizes.
How They Work
A floating de-icer sits on the water surface and generates just enough heat to prevent ice from forming in a small radius. Most units draw 100–300 watts — far less than heating the entire pond. Pair with a winter aeration system for maximum gas exchange. Pro tip: place the de-icer near the pond edge (not the center) and away from the deepest point where koi rest in winter. This keeps the warm zone at the surface without disturbing the warmer stratified water below.
