I've been doing my reading, and it seems I need to have a layer of iron rich substrate, then a layer of normal aquarium gravel on top for good growth etc. I like the idea of doing it this way as I like the colourful gravels in aquariums.
How do you go about cleaning though when you have a very fine substrate under the gravel?
Ordinarily just using a gravel cleaner things pulls up the gravel and gets the dirt/old food etc under the gravel - but how does this work if there is finer substrate under the gravel?
