Concerned about Substrate

[Theos]

Hey all I have a question.
I'm running a 60cmx30cmx30cm tank.
My substrate consists of 3-6cm of silica sand and 1cm of Seachem fluorite(ontop). Im worried that some of the plants that send roots deeper down into the substrate will not do well in my tank, and I should instead mix the gravel up(however I like the Dark Seachem look).

Don't worry about it, plants root in sand just fine. The only thing fluorite offers for nutrients is iron, and the rest comes from dosing and plant deterioration that builds up over time.

Your plants ought to do fine. If you were to mix it the lighter Fluorite would probably end up on time over time.

Ah ok cool, thanks for the info.
