I have a 10 gallon tank, fairly large gravel substrate, several fish, and plastic plants. I would like to try some live plants. Here are my questions:
1) Can you effectively change out the gravel with a plant friendly substrate? Or should I just wait for my next tank?
2) At what point does CO2 injection become necessary? Could I do OK without it with just a couple live plants?
