this is the base fert we'll be using here... i was actually thinking of getting JBL's florapol from Mizu world but i was too impatient so i just whacked the cheapest one from C328. costs less than $10 and PERFECT amount for 1ft cube.
here's the base fert, covering the base of my tank with roughly 5mm-10mm thickness.. pretty crumbly as you can see...
laid the lapis on top of the base fert... total substrate combination is at 4cm thickness at the front.. did two hilly slopes... not sure if they would stay there after the water is filled in or not...
