I have a new 75 gallon tank that I want to moderately plant and put 6 or 7 discus in. As far as filters, Co2, and lighting go what do I need? I want to be able to satisfy the needs of 90% of the plants out there. I do not care about breeding per say but I want the discus to thrive. I already have a water change system and mantenance down but I need some help on equipment!
