I am returning to the aquarium hobby after 10 years away. I had just started growing plant with CO2 when I was forced sell out all of my tanks. I have just set up a dry startup with Amazonia 2, several tissue culture grow out plants, and a 46.5 in. Finnex 24/7. Surprisingly, the plants are responding Well to the change in light from my inexpensive grow out closet tanks. I have several questions that I need to resolve prior to immersion. 1) Will I need a second light fixture to provide adequate light for high light plants? 2) Does anyone have a bullet-proof CO2 reactor to place inline with the FX6 that will filter the tank? Tank shot is attached.
