Aquarium Advice Freak
I have a 20g tall tank it's cycled and empty from having it running before (kept same filters in it to keep it cycled ) switched gravel to eco complete and bought the fluval led plant light. I have some sword , anubias, and dwarf grass in it currently. I plan on planting more in it. Is it absolutely necessary to have co2 system in this tank? What do you all recommend I do? I'm setting this tank up for a few dwarf puffers. I have 2 aqua clear filters in it one for a 20g and one for a 40/50 gallon. Any advice would be appreciated
