I've decided to go with a minerlised top soil substrate and came across a nice tutorial on how to do that.
The only question I have is relating to a concern about the compaction of fine soil substrates.... I had the problem with the westlands aquatic compost that the first couple months were great, then the soil literally turned to a cement like composition where even my crypts roots couldn't bust through at all.
Is there any way that I can stop this happening? I'm only going with about an inch of soil capped with fine gravel and sand.
