Anybody use the subsrate from aquariumplants.com (http://www.aquariumplants.com/Freshwater_Aquarium_Plant_Substrate_p/ss.htm)? I'm about to buy 12 gallons of the stuff myself for my 150 gallon tank.
For my first planted tank, I used generic gravel. Not the pea sized kind either. When I first set it up, I didn't even consider putting in live plants. I'm guessing thats the reason why it took a while for my plants to finally start thriving.
Not worth it. It is almost identical to turface/soilmaster select, I've read.
For the quantity you're buying, ADA aquasoil isn't much more expensive.
