If the water in the large backyard pond is dirty, the waterfall is just dripping and the filter does not seem to be doing its job, you may only need to clean the filter to get your pond back in top shape.
- Turn off the electrical power to the pump, either in the fuse box, by placing the switch or pulling the plug. Do not work on anything in the pond with electricity in turn.
- Remove the outlet hose from the coupling. If it is connected with an o-clamp, you will have to use a screwdriver to loosen it first. Let all the water discharges from the pump – large pond filters are heavy and difficult to move if they have not been consumed.
- Remove the inlet hose in the same way, and if your filter tank has a Venturi valve, remove that too.
- Move the drained filter pond to a place near your garden hose, where it will be convenient to clean, such as the lawn.
- Put on the rubber gloves and remove the filter pads. Clean with a strong jet of water from the hose. Do not rub them. Put the floor on the grass to dry. Resist the temptation to clean the pads and other parts of the filter flawlessly. The only thing that wants to get rid of most of the dirt and debris. Do not use detergents or cleaning products from the filters … or any other part of the pump or pond. Cleaning products contain chemicals that can kill your plants and fish, and can eliminate the beneficial bacteria your pond needs.
- Overturning of the filter media – ceramic rings, zeolites, activated carbon or volcanic rock. Clean it with a strong jet of water from the hose, or swish it in a large bucket of tap water.
- Return to place the filter medium and level out. Replace the filter pads, with the thicker pad on the top. If the pads are worn, permanently clogged or deformed, replace them now.
- Remove the pump from the pond, if possible, out and spray with the hose to remove dirt and debris. Find and eliminate any obstruction. Return the bomb to the lagoon.
- To place the filter in its place. Reconnect the inlet, outlet and venturi vent hoses, hardening or -clamps as required. Turn the power again.
Tips and warnings
- Keep an extra set of filter pads in your hand so you can replace them when necessary.
- Never use pond gloves in the kitchen … water bacteria in the pond can make you sick.
