What are the dimensions of this tank?
For lights it really depends on what you want to go for. Medium light will require less than high light. I will say that i would go with leds over t5ho. The finnex planted plus 24/7 is an excellent fixture.
You will also need fertilizers. I would suggest either pps pro or estimative index.
Substrate - skip the gravel and go with sand instead. pool filter sand is good for that. Sand is easier to anchor plants in. Depending on the tank dimensions it will need more, so once we know that i can make a suggestion as to how much.
