Gravel base OK for eco-complete substrate?
I'm new to making a planted aquarium. Last night I put a layer of ordinary aquarium gravel taken from an established tank up to 1" thick in my 75 gal aquarium, then placed 3" eco-complete on top. I put the aquarium gravel on the bottom so I could get a "lift" towards the back and to the sides without having to buy extra bags of eco. Is this process OK or will I have problems? I later saw on the eco-complete bag that you shouldn't put their product over established gravel. Should I just mix everything together, try to remove the gravel, or just leave as is? Thanks for your help, I'm a little overly cautious about the substrate, since it seems like it would be the hardest parameter to change once you get everything set up. FYI - right now there is about 40lb gravel to 120lb eco.
