Hey I'm gonna be setting up a planted 29 gallon with guppies and at least half or more of the plants I want to get are heavy root feeders like dwarf sag, crypts, and sword plant. but I'm trying to decide between gravel, aqua soil or eco complete. I really like the look of the gravel compared to the planted substrates but I don't get the benefits, could I cap the planted substrates with gravel and it work the same? will the plants do fine with just root taps in gravel or is it just better to spend the money on planted substrate? what would you do and what's your personal preference? last thing is what's better eco complete or aqua soil? I have hard water so the aqua soil would benefit the plants a bit.
