I'm setting up a 125 gallon planted tank. I already ordered two 36 inch marine land led aquatic plant lights. I'm planning on purchasing Eco complete planted aquarium substrate. A few questions:
1. Is it necessary to inject co2 into the tank or will the lights and gravel mentioned above be sufficient? 2. Any recommendations on types of plants to purchase?
I currently have Amazon swords in a 55 gallon with a basic led light and cheap gravel. I use florish and the tank gets natural light from its placement by the window. At one point my swords were littered with holes. The addition of florish iron, potassium, and phosphorus has resolved that issue. The swords are doing fine but they are not thriving which is to be expected with inadequate light. Any advice as I setup my 125 gallon is appreciated! I plan to keep Angels, tetras, barbs, and maybe discus in the tank.
That depends on the "look" you want (high-tech planted with rapid and dense growth vs normal density & growth), types of plants (certain species need added CO2, most dont), types of fish (certain sensitive species might be harmed by elevated CO2 and ferts), and how much time you want to spend trimming and thinning plants. With swordplants, I personally DONT want them to grow fast! People kept beautiful planted tanks for 100+ years before CO2 supplementation came along.
