Advice on turning a 90 gallon fish-only tank into a planted tank
Hello folks! A little background on me: I've had a 90 gallon non-planted freshwater tank for a year, housing an Oscar fish. Unfortunately my O died a few days ago, and I'm looking into doing something different with my tank, whether that means going reef, planted, or otherwise. I've surfed around your site a good bit here (great info), and while I think I've got a decent idea of what it takes to run a planted tank, I'd like a little more info.
First off, my current filtration consists of two Eheim 2028s. I assume those can stay if I decide to switch to a planted tank. My heating is taken care of with a 400W Hydor Theo. I assume I'll need lighting, new substrate, and some kind of CO2 unit.
Lighting: What kind of lighting do I need, and how many watts? What brands do you recommend?
Substrate: What kind? How much for a 90 gallon? Any brand in particular I should buy?
CO2 unit: Again, what brand do you recommend?
Also, if you could give me an idea of how much each new piece of equipment would cost, and how much the recurring costs will be (CO2 refills, possible extra electricity bill expense), I would really appreciate it.
Thanks in advance for taking the time to help out a planted tank newbie!
