So, ever so slowly, I've been acquiring everything for my 50 gallon planted. I've never used organic miracle gro in a tank and I'm wondering what folks think of the following... About 1 to 1.5 inches of the dirt capped with about 1.5 inches of eco-compelte (because that's what I have readily available). Pat down the dirt to try and get as much air out as possible. Fill the tank. Empty the tank. Fill the tank. Empty the tank. Fill it and let all the particles that continue to float eventually fallback down. Once that is taken care of, I will begin planting a nice carpet of dwarf sublata with jungle val in the background. Any other tips or suggestions for a dirted tank? How long would you say this substrate, given the plants above, might continue to provide root nutrients before tabs should be used? A year or more?
