So I have a 20 gallon cichlid tank, doing good
I want to spice things up and get some plants. I have been researching some. I am however still confused on this light thing. Do I just need to buy a new bulb? Or do I need a whole new light unit?
Second, what about this filter? I have a filter with two sponges in it that hangs over the back of the tank ya know? Just a regular nothing fancy filter. Do I need a special filter for a planted aquarium?
Third, the CO2 thing. Do I need to add CO2 myself? I don't want to get one of those big tanks. Can I just add EXCEL? Or what?
Last, I have blue gravel from Walmart. It's not fine gravel, actually I think it is kinda big. Do I need specail gravel? Like sand? Or will my blue gravel work just fine?
Oh I'm so confused
Any other suggestions for a newbie would be very much appreciated. Thank you for your help.
