Hey Guys,
I have had a Saltwater reef setup for 10-15 yrs and it crashed a few years back and I lost everything. I cleaned the tank out and it has been sitting every since. My vision is to setup and maintain a Freshwater Planted community tank. What I have is a 75 gal tank with a built in overflow that drains down into a 15 gal tank with a return pump. It has a LED light system that I can control the color and intensity and 2 power heads that I can control output on them also.
I am looking for some suggestions on if I need to change anything out or add something. I am looking for suggestions on Substrate, fertilizer pellets that go under the substrate. Do I need a water filter system or will dechorionize be good enough for the water?

Thanks in advance for any help.
