Regular maintenance now is particularly important for the smaller pond and patio container pond as you can accumulate significant amounts of rotting vegetation in a small volume of water.
1. Remove tree leaves that arrive in the patio pond water.
2. Prune back the plant foliage so that tall upright plants will not drop their leaf into the water.
3. Remove some of the rafting plant growth. Control excess spread and allow more light into the pond water in Winter.
4. Leave all oxygenating plants in place for now and thin out in Spring if you have more than 1/3rd of the volume filled with them.
5. Stop adding extract of barleystraw once the clocks change in October but resume adding fortnightly again when the days brighten in Spring.
Doing these tasks will reduce the chances of formation of sludge on the container bottom and makes the need to completely clean the out the container pond less likely. Ideally you would manage the silt like this and never need to throw out the water and start afresh as that will always mean having to mature the water again and the newly added water will potentially bring with it nutrients or chloridamides.
Remember as Winter gets colder to check the water level stays just below the level of the container rim so that there is space for the water to expand if ice should form on the surface of the water.
