I'm new to keeping planted tanks, and I'm kinda confused on what I need to do to help them grow, besides light.
I have a CFL 6500k daylight bulb on my tank that I have on for 12 hours a day.
What do I need to do to fertilize my plants?
I've seen this stuff called Flourish Excel, but from what I've read that just adds co2 I think? Do I need that? Is there an alternative method? I've been poking the gravel around, because I think I read that what another way to do it.
But what about fertilizing? Is there something else my plants need?
In my tank I have anubias, and java fern right now. But I have ordered duckweed, dwarf water lettuce, and amazon swords which should be here any day now.
The duckweed and water lettuce are also going in my pond, so I planned on growing them in a bucket first outside and then distributing it between tanks and the pond, or is that a bad idea? It's just a 20 gallon green bucket like this
one. Would I need to fertilize these ones too?
