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).
I would skip the sand, just use Flourite. 1 cm is so shallow that there will not be much root growth that stays that high up, and any plants with that shallow a root system will get pulled out of the substrate anyway.
