I have been keeping the water level below the outlet (The previous Klargester Tank enquiry) to the filter bed by pumping out every few days. Obviously the filter bed does get wet when it rains, but I am keeping the Klargester water away from it for now. Is this the right thing to do and should I continue to do this whilst treating the filter bed with eco septic tank treatment as per your recommendations.
We like the idea of adding eco septic tank treatment directly to the top of the bed rather than trying to draw it in from the tanks. We would suggest that after adding the product to the top of the bed, the tank could then be pumped out so that liquid flows back into the tank and so that the microbes will be drawn into the filter bed so that they can do their work.
Yes, we did mean that after mixing the product with warm water in a bucket, not all of it will dissolve in the water and, therefore only the dissolved product should be added to the filter, putting the remainder of the un-dissolved product directly into the centre chamber.
Finally, yes it is a good idea to keep the flow through the bed to a minimum whilst the microbes do their work, say 3-5 days, and so they do not get washed away. After that it would be helpful to have a high flow of (as clean as possible) water to wash out any loosened debris.
