What Size Pond Deicer for A Backyard Fish Pond?

Question about pond deicers for a fish pond.

Q: "What kind of pond deicer is best for a fish pond located in Illinois? I don't understand why I need to heat the pond as long as there is a hole in the ice." Thanks. Roger.

Answer: For under $75, you can forget about checking your fish pond daily in cold weather to keep that hole open in the ice. The pond deicers we sell are thermostatically controlled. The electricity costs are nominal compared to the cost of replacing fish due to gasses trapped under the ice. I recommend that you choose a pond deicer according to the size of your fish pond and the depth of the water. We sell deicers from 500 watts for 50 gallon backyard ponds to 1500 watts. For example, the Allied Precision 1500 watt floating pond heater is quite popular as is the Farm Innovators Heated Pond Saucer for small ponds.

Pond deicers float or sink to the pond bottom. The heat generated keeps a hole open in the ice and lets gasses escape from the pond during freezing weather. If you have Koi in your pond and the population has been constant for years, the fish are unlikely to become victim to Koi herpes virus. If you introduce new fish, remember that this disease can remain latent for long periods of time. The virus becomes active only at temperatures between 15C and 28C. No treatment is available. Mortality in Koi is between 50 per cent and 95 per cent. Pond heaters, that maintain specific temperatures in ponds, should be custom designed by pond experts.

Thanks for your question.

Sincerely, Barbara
