I'm going to trying my first attempt to water filtration and I want to start with a filter composed by these layers (from top to down)
- coarse rocks
- medium rocks
- coarse gravel
- fine gravel
- carbon
- sand
In these type of filters can you explain which level of filtration you obtain? bacteria? Chemicals? Any resource with strong evidence for reference?
Will an approach with
- medium gravel
- sand
- medium gravel
- sand
- carbon
be more correct?
