I have a 20 long set up. looking to grow plants but plan to focus on low light. I only have about 1.5 inches of gravel in the tank.
Is it important to add more gravel - maybe to get closer to 3 inches?
If not gravel, is there something else I should mix in to supplement the gravel?
Thanks in advance
