Cooler Fall tempretures are here bringing ice to our ponds

It seems to have taken a while but Fall temperatures are finally dropping. Temperatures are now down to the expected levels for this time of year. With this colder weather we are now seeing frost and the formation of ice on our ponds.

Before ice becomes an issue for your pond it is a good idea to have a plan for keeping a hole in the ice on your pond all Fall and Winter. This will give the build up of unwanted gas in your pond a way to escape.

An air pump is an excellent way of keeping a hole in the ice on your pond. The movement of water stops your pond from completely freezing over. It is also a much less stressful way of making a hole that using boiling water or brute force which may harm your fish. Ensure that the air pump has an insulated housing so air that is pumped into the pond is dry and not freezing. This will also provide protection for your pump and can be decorative also.

It is best to plan ahead because Winter is on its way and we want to ensure that our Fish and other pond life thrive and come to no harm.

FujiMAC Air Pumps are available for purchase

Fish Pond Products have FujiMac Air Pumps in stock, in various sizes, that are perfect for providing aeration to your pond. We have in stock the MAC40R, MAC80R, MAC150R and MAC200R.

FujiMac Air Pumps:

  • Provide long life operation. These air Pumps have minimized housing temperature rise so your pump has extended use. They are tested for endurance.
  • Are energy efficient. The efficiency of the pump means that it consumes less power and so it therefore costs less to run.
  • Are easy to maintain. No lubricant is needed for these pumps. The diaphragm assembly can be easily replaced with the purchase of a rebuild kit.
  • Have a simple structure. These pumps are Oil-less and have proven, strong durability.
  • Have quiet operation. These pumps have an established noise suppression mechanism to ensure quiet operation.

Reasons Aeration in your pond is necessary

Aeration infuses oxygen into the pond. Adding pond water aeration is beneficial for your fish who need oxygen to survive. It also improves the overall health of your pond’s ecosystem.

  • Aeration reduces pond sludge. Through time nutrients accumulate at the bottom of your pond and become muck. It is this sludge at the bottom of your pond that can give ponds a bad smell. Aeration increases the dissolved oxygen and circulates water. This pond water aeration encourages the colonization of beneficial aerobic bacteria that consume the nutrients to reduce existing sludge build-up. It also prevents sludge from accumulating in the future. If you do not have sufficient oxygen in your pond you will not have beneficial bacteria in your pond. Beneficial bacteria produce harmless gas when breaking down the sludge and other matter at the bottom of your pond. You will have anaerobic bacteria which produce carbon dioxide and hydrogen sulfide when they break down all of the sludge at the bottom of your pond. This is what causes the nasty smell. Clearly when you have plenty of aeration you will have aerobic bacteria which are beneficial to your pond
  • Aeration improves water clarity. When nutrients accumulate at the bottom of your pond and result in sludge they also cause your pond to become cloudy. By reducing the nutrients with aeration and therefore sludge you will improve water clarity.
  • Aeration will reduce the quantity of algae and weeds. There will be less nutrients in your pond because you have increased circulation. You will also have increased oxygen and therefore there are less nutrients to feed algae and weed growth.
  • Aeration boosts dissolved oxygen levels. Fish and bacteria in your pond need oxygen. Aeration encourages contact between the water and the environment, which will increase the dissolved oxygen level in your pond.
  • Aeration prevents large temperature and oxygen level differences in your pond.  A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below. In your pond this means that the bottom of your pond is colder than the top and so the bottom of your pond has less oxygen than the surface. In a well aerated pond the water movement means that the cooler less aerated water will be forced to the surface to warm up and gain more oxygen and the warmer oxygen rich water will go to the bottom of the pond. This means that the temperature and oxygen levels are more consistent at all levels in your pond.
  • Aeration prevents your pond freezing over. If your pond freezes over the gases produced when bacteria breakdown organic matter at the bottom of your pond can not escape. This will therefore mean the oxygen levels in your pond will deplete and can result in fish suffocating. If you aerate your pond you can keep a hole in the ice which lets the unwanted gases escape and allows oxygen into the water.

Oxygen Levels in your pond

There are many factors that will effect the oxygen level in your pond but the main ones are:

Temperature: Warm water has a lower ability to hold onto oxygen than colder water

Animals: The more pond life you have in your pond the higher the amount of oxygen that is required and used up

Water Clarity: Pond plants need light to generate oxygen. The clearer the water the more effective your plants will be

To improve water clarity you may want to consider a pond additive. An air pump will assist in increasing oxygenation in your pond.

 

 

 

When does a Pond need Aeration?

Aeration is a very crucial element in any pond.  Every living thing in the pond requires a constant supply of oxygen and every process that happens in the pond is dependent on oxygen. The fish, plants and even the bacteria need oxygen. 

Aeration is important:

  • At Night:

This is when plants are not converting CO2 into oxygen.  

  • In Winter:

During winter months in colder climates aeration helps to keep a small hole open in the surface of the pond to aid in degassing

  • In Summer:

As water warms up it is unable to hold as much oxygen so dissolved oxygen levels are generally lower in warmer water temperatures. Aeration will also help to circulate your pond and prevent stagnation and so reduce the number of mosquitoes that can breed in your pond.

An Air Pump will supply aeration necessary for your pond all day and all year long.

Oxygen in your pond

Oxygen is essential for your pond. It prevents your pond turning into a stagnant, smelly, swamp where nothing will grow and thrive except algae and mosquitos. The main ways to introduce oxygen to your pond are from the surface, which is why keeping a hole in the ice during the winter is necessary, and also by mixing with water movement. An air pump will provide aeration that supports both surface aeration and air movement.

Air Pump Rebuild kits

If you have an air pump in your pond it is likely that eventually the the diaphragm will wear out. The benefit of many pumps on the market is that you can easily remove worn diaphragms and replace them using a rebuild kit. When initially purchasing an air pump it is recommended to also cost the rebuild kits and even buy one so you are not caught unawares with no way to fix your air pump.
