Well, I'm not so sure about the gravel myself. I've been thinking about changing it to Flourite or Eco-Complete. But thats a job I'm not looking forward to, so I'll wait untill I get sick of this layout. (knowing me, that wont be long)
Must4ng S4lly - wow - thanks for the kind words. What I'm doing is fertilizing, using the complete line of flourish products, and I'm injecting Co2 (DIY), and I have 65 watts of light for my 20 gal tank.
That, and a lot of fiddling around (cant keep my hands out of the tank)
-WOW- obviously you have an aquatic green thumb! The plants in your tank look fantastic. Like Leopardess, the gravel colour isn't my cup of tea, but I know what a task it can be to change that stuff out (oy!).
