The low tec tank i am setting up is going to have a bottom substrate of laterite as a clay 2 inches thick, followed by a layer of peat moss then 2 inches of aquarium gravel 2-3mm in size.

The peat i bought states that it has "NITROSOL" in it. Does anyone know what the chemical composition is? Is there ammonium/urea in NITROSOL?

If there is NH4+ is this conducive to promoting algal growth? I thought plants' primary intake of N is as ammonium as this requires the least energy expenditure. Is this not a good thing?
