Hi Akira,

There used to be two inexpensive Montmorillonite clay products (Soilmaster Select Charcoal and Turface Pro League Grey) but they have been discontinued for several years now. The only dark alternative would be the aquadurt sold by in the Black Diamond color.....but it is substantially more expensive.

45 Gallon Tall; 96 Watt AH Supply CF; 6700K; & 30 Gallon Long; 2X36 Watt AH Supply CF; Press. CO2; UGF; Heat Treated Montmorillonite Clay
