Sand vs Flourite?
I currently have sand in my set up, and was thinking about redoing the scape as some of my more light demanding plants are shadowed, and vice versa.
The sand in my set up stuffed with tetra initial sticks and seachem root tabs, and was wondering if this is sufficiant for a mid to high tech set up. I'm running CO2 at around 15ppm, dosing seachem NPK according to their dosing regime, flourish, flourish excel, and kent Iron and Manganese.
I'm achieving good growth in some plants, yet others just aren't growing and I'm assuming it's due to their position in the scape.
Would switching out the sand for flourite be better? also I still want the sand is it possible to place it over the flourite?
