Pond cleaning checklists
As part of your pond keeping duties, you need to keep your pond clean in order to avoid water clarity issues. You can do this by tending to pond plants to ensure they aren’t overgrown, netting surface debris and not overfeeding your fish.
Keeping on top of debris before it has a chance to decay will also help. This Hozelock Pond Grabber is also a great tool to have by your side.
Every autumn you’ll also need to deep clean your pond. The most effective and convenient way to do this is to use a pond vacuum which suck up debris such as fallen leaves, fish waste and blanket weed. We’ve written a FAQ on pond vacuums which you may find useful.
Keep a healthy pond balance
Stocking levels will vary depending on filtration and type of fish you wish to keep, however a general rule for stocking is 25 cm of fish per square metre of surface area or 55cms per 1000 litres volume. When stocking your pond, keep in mind your fish will continue to grow and breed and an overpopulated pond will lead to excessive fish waste and imbalanced, unhealthy, water.
Don't over feed your pond fish
Over feeding your fish is probably the one main causes of poor water quality. It is likely not only to cause water clarity issues due to algae thriving on any excess nutrients in the water, but it is also can cause high levels of toxins directly affecting your fishes health. Read our easy to follow guide on feeding your pond fish.
Have a balance of pond plants
Pond plants play an essential role in maintaining the pond health, they absorb nutrients which could otherwise feed the algae that turns your water green and allows blanket weed to grow. They also help to reduce light levels in the water, preventing unwanted algae bloom. Read our guide to pond plants.
Maintaining your pond filter
A biological pond filter typically will only need maintaining a few times a year, according to the manufacturer's instructions.
Tips: If you need to rinse your filter media, never use chlorinated tap water as it may kill the beneficial bacteria which colonising your filter. This helpful bacteria plays a vital roll in breaking down the harmful toxins in the pond water. We recommend using a bucket of your pond water to "gently rinse" your filter media just enough to allow water to flow through freely. (You should only thoroughly clean biological filter media if you shut your filter down for the winter).
After maintenance, or in the spring and when starting a biological filter for the first time, add a biological additive to kick start the biological filtration process in your pond filter.
A biological pond filter must run 24 hours a day to be effective
