I have an established 60g that I'm thinking of converting to a planted tank this summer. I want to dig out the gravel and replace it as well, but I'm not sure if that's going to throw my cycle out of whack. I don't have any particular plants in mind yet because I'm not too picky about them, but this is about what I'm thinking:
-LED Pent 48" HI Lumen Timer Ready 6500K (6800 Lumens Super energy efficient 0.5 watt high output LEDs
180x 6,500K LED)
-Bottom layer of organic soil
-Mid layer of flourite
-Cap layer of black sand or something similar
-Planning to search the area for local driftwood
-Also planning to build some slate caves as well-- is there a general weight limit for adding things to glass tanks?
I don't know yet if I want to do CO2. Could I manage without it, or is it a necessity? I also wonder how long the fish will have to be out of the tank while I'm converting this.
