Use a net or pond vacuum to clean the debris from the top of the pond. Any organic material left in the pond will decay and cause algae problems like green water and sludge. Removing it is the first line of defence against algae problems. It’s also worth clearing the surrounding area to prevent anything blowing into the pond.
Move fish back into the pond
If you’ve moved your fish into a temporary tank during the winter, now is the time to get them back in the pond. It’s important to ensure the temperature of the tank is within 1°C of the pond temperature.
Clip back and trim plants
Spring is the best time to have a general tidy up of the pond area. Overgrowth can be a large factor in an imbalance in the pond system.
You can start feeding your fish again at temperatures of 10°C and higher.
Start treating your pond
The earlier you can start treating your pond the better. Envii’s pond products work as low as 4°C which means you can get started earlier in the spring and treat later into the autumn. Giving the bacteria longer to establish will greatly increase the chances of keeping your pond clear and healthy. Click here for more information.
Clean your filters
Most bacterial water treatments will dislodge any algae or sludge and it will get sucked into the filter. If the filter gets clogged it will stop filtering the water and become completely useless. It’s important to clean them regularly for water treatments to work efficiently.
