Hi there.
I have a question to the expert's out there.
Why are you guys recommending to use silica sand and not crushed coral as a substrate.
Surely the coral is more porous which means that more organisms can live in them.
Is silica sand not completely impermeable?
A recommendation was made on my tank to remove the crushed coral, rather course variety, and to rather use silica sand.
Hence my question?
