Sand as top-off, will it compact with fluorite?
I'm planning out my 105 gallon, and I cannot really find the answer I'm looking for through PT search. I plan to use sand from HD, not sure as to the color or type (blasting sand or pool sand) and will go on top of fluorite original color. I assume I'll use about a 1/2" of sand.
Here's my loaded question. Will the sand eventually sink down below the fluorite and potentially become compacted, or will the sand stay on top? Or should I mix the sand with the fluorite at the top 1-2"? I plan to only do this at the front where it is visible and will use the foreground plants. Ultimately, I'll use laterite mixed with fluorite and the bottom inch or so for the whole aquarium bottom, then a layer of just fluorite, then capped off with sand just at the front for visual, any suggestions would be great. Thanks in advance.
