Pond Maintenance

tap-water-no.jpg Chlorinated tap water should never be used  to clean pond filters as the chlorine in the tap water kills the beneficial bacteria in the filter. Instead clean filters in a bucket of water removed from the pond.

 

Pond Maintenance Tips

• When replacing the filter materials, do not replace all the foams at once as this will set back beneficial bacteria. It is better to stagger the change over a few weeks.

• Pond equipment should be regularly checked and cleaned, as per the manufactures instructions, to ensure the longevity of the ponds equipment.

• Clear water does not necessarily mean good water quality.

• UVC filters generally need to have their globes replaced every 12 months as they lose their effectiveness after this time. O-rings should also be replaced at the same time.

• When changing the water or topping up the pond or water feature, we  recommend using an in-line filter with activated carbon attached to your hose to help remove the chlorine when filling your pond.

• Statuary water features are able to have their water topped up every so often but every month a 1/4 to 1/3 water change should be done to remove any build-up of minerals such as calcium. As the water evaporates these minerals concentrate, affecting the performance of the pump and attaching themselves to the water feature and pump causing pump failure and unsightly stains. Pumps that are affected by minerals are hard to clean so regular partial water changes are necessary to prevent the build-up of minerals. Pond equipment seized up by calcium and other minerals may not be covered under warranty.

Why does my pond smell?

A pond should have no odour, if it has a bad smell something is wrong. Possibly your filter is under sized or requires maintenance, or there could be decaying sediment on the bottom of the pond which needs to be removed.

How can I stop my pond from going green?

uv clarifierA green pond can be caused by several factors. These include lack of filtration, incorrect pH values, overfeeding and overstocking of fish, excess sunlight and lack of proper maintenance. If your pond is well filtered and is still green, often the pH may be too high or low, causing the filter to work inefficiently. High pH levels can cause several problems, such as algal blooms because of the favourable conditions for it to flourish. Overfeeding & or overstocking of your pond can be easily rectified by simply reducing the amount of food given and also the amount of fish. Excess sunlight can also lead to problems with algae blooms. Increased filtration and the use of an Ultra Violet Clarifier will help solve this problem. Alternatively, a cover can be erected over the pond to give more shade. Algaecides are also available, and these are most affective when used as a short term remedy. Sometimes after a long holiday or when regular maintenance has not been possible, an algaecide can help regain the balance and clarity of your pond.

I have lots of stringy algae that looks like hair, what can I do?

String Algae is usually a sign of an imbalance within the pond. Reducing the amount of feed and ensuring you have a good biological filter that operates 24hrs a day will help remove excess nutrients from the pond. String algae prefers water with high pH so testing your water and reducing your pH with Clearpond pH down or Oase pH minus will also help.

 Pond Cleaning

  • Remove leaf litter and floating debris frequently, sunken and decaying leaves produce ammonia. Products such as surface skimmers will act in the same way as a swimming pool skimmer box and catch the leaves before they can sink.
  • Do a partial water change once per month to reduce the build up of nutrients. At least change one third of the water volume every three months.
  • Use a brush to scrub off excess benthic algae, you can leave some algae if you want as if you have koi they will eat it.
  • Pond plants are a source of removing excess nutrients and oxygenation, but be sure to trim off any dead or dying leaves or they will break off and sink to the bottom to decompose.
  • Pond bottoms can be vacuumed clean of debris by using a special vacuum cleaner for use in water such as the Oase Pondovac 4.
