Flourite plus sand work?
Would Flourite topped with 1 inch of sand work? Wondering if the sand would become a barrier between the water and flourite hence making the flourite useless. I'm planning to use sand on top to plant a carpet.
As for the sand, are there any types of sand that won't work? From what I've read in this forum people seem to do okay with any type of sand, even sand bought from home depot.
