Although winter may be coming to an end, freezing temperatures are still predicted and Dan Everton from our Aquatics Superstore recommends using ice prevention products to safeguard your pond.
By preventing ice from forming, toxic gases from decaying vegetation in the pond will escape and oxygen is allowed into the pond. Essentially these products may be life savers for your pond and its inhabitants.
Pond heaters are very effective at keeping at least part of the pond surface ice free. These are relatively simple devices with heating elements, cheap to run and very effective.
There's a wide choice from all the well known aquatics companies ranging from the 50w Blagdon Ice Vent to the Cloverleaf 4kw Digital Pond Heater with a titanium element and thermostat.
Velda Pond Heaters and Oase IceFree Thermo heaters also have thermostats for energy efficiency and can keep a portion of the surface free from ice even at very low temperatures.
As an alternative to heaters, aeraters can benefit your pond throughout the year.
In cold weather they keep a pond ice free while increasing oxygen and reducing carbon dioxide levels. This will also prove particularly useful in the summer when fish are active and oxygen levels decline.
The most basic Pond Heater Alternative works off only 4w, the same as the smallest Blagdon Pond Air kit suitable for ponds up to 2250 litres. Other Blagdon Koi Air Pumps are designed for deeper water and have a maximum flow rate of 25 litres per minute.
Oase AquaOxy pumps and OxyTex aerater/filters are designed for ponds up to 20,000 litres. They are also multi-functional, supplying oxygen, increasing circulation and encouraging nutrient decomposition.
High performance and very reliable Hozelock Pumps deliver a maximum air output of 75 litres per minute, ideal for the majority of fish and koi ponds. Up to 12 air stones can provide oxygen to various areas of the pond and the pumps can be used in conjunction with Trinamic filters.
