Currently have laterite+gravel, want to add flourite, how?

I Currently have laterite+gravel, want to add flourite. Is this doable? I am trying to get a carpet/lawn established of dwarf hairgrass and the gravel doesnt seem to be cutting it. I have 1 bag of flourite laying around and figured I might as well put it to use somehow. Would I just rinse the flourite, and drop some where I want the carpet/lawn to grow? how far deep should I mix it?

Is there any other way to establish a lawn of dwarf hairgrass (or any other type of lawn) with gravel? Can someone name some plants that do well in my conditions? (4WPG, co2 injected, seachem's line of nutrients)

If your "gravel" is small, 2mm to 3mm or so particles, you should be able to grow a lawn without the flourite. The problem is to be able to plant the little plants without them all floating out. Make sure you are dosing enough NO3, PO4, K, etc. and keeping the CO2 up around 30ppm all during the lighting periods. In my opinion the only good reason for a substrate change would be to get a substrate appearance you like better, or if you have a really bad one in the tank. Once your lawn grows you can hardly see the substrate anyway.

Those are what we call bricks!! Seriously, that is gravel, but too coarse for tiny plants, in my opinion. If you add a finer substrate on top of it the finer stuff will just settle down to the bottom leaving the coarse still on top.

depends on how deep your substrate bed is and, in my experience, dwarf hairgrass roots aren't all that long. So, if you already have a 2" gravel/laterite bed and you dump in an inch or two of fluorite, I don't think it would work too well.

How about removing some of the gravel from the front where you want to plant and add the flourite and maybe sprinkle a little gravel back over it just for appearance.
