Koi winter routine We have cleaned both the Nexus 310 & the EB40 Bead filter on our main pond today. These filters are flushed 3-4 times a week at this time of year. The covers are helping maintain the pond at 10.5°c along with the stock tanks at 16°c. If your pond is covered, ensure you allow the pond to breath to prevent a build up of toxic gasses.

The Ph is 7.6, Kh is 5.8 and no nitrite is showing at all. It is essential to keep a close check on your water parameters to prevent a pH crash which could be lethal for your fish.
