I want to start planting my 29 gallon tank that I want to raise cories in. I'm coming into this with no experience on keeping plants in an aquarium. I have a 30 inch Marineland F18T18 Natural Daylight bulb (18 watts). Is this enough light and if not is there a cost effective way to increase it? Also what substrate is actually needed and can I DIY substrate, since 15-20$ for a 15-20 pound back is ridiculous. Is CO2 injection necessary or worth it? Fertilizers (cheap or none if possible) Is there anything else I should know? Any plant suggestions? I have hard water (pH 8.0-8.2) and will keep the aquarium on the cooler side.
