You can do either; use it as a cap or as a substrate by itself. Tylt33 is correct, it contains minimal nutrients but is a excellent inert substrate with a high CEC.

Below is a picture of my 10 gallon with Safe-T-Sorb that I planted about 5 weeks prior to the picture being taken. It has two 10 watt 'daylight' cfl bulbs and I fertilize with Seachem Flourish Comprehensive and Seachem Excel for extra carbon molecules...nothing else is added. I am doing an experiment with the tank, I grew all the plants pictured emersed and moved directly into the tank; no CO2. Nothing 'melted' (including the crypt), nothing died.

75 Gallon, 2X55W AH Supply CF 8800K, 1XMarineland Doublebright, 2X Marineland 350 Magnum; 45 Gallon Tall, 96Watt AH Supply CF 6700K; 30 Gallon Long; Fluval F&P 2.0 36"/46W; 20 Gallon, 1X26W AH Supply LED kit; all with Press. CO2; (Calcined) Montmorillonite Clay
