Fish Crazy
I recently bought a Fluval 205. It adds a good amount more SW to the system (im guessing around 2gal). I put charcoal in the bottom cartridge and still have 3 empty cartridges. I was think i can probably fit around 3lbs of live rock rubble. My question is..... Does the rock need a light source to thrive and also will i have to rinse the rock regularly or can i just leave it in there with no maintenance?
