one gallon lighting question
Salutations plant friends! I'm new to this, but I currently have a one gallon Iwagumi style tank that I just currently got done planting. I have fluorite with a thin layer of sand, just a couple of rocks with some Anubias around them. The bulb that came with the tank is 9w but I have this sneaky feeling its not enough. I can't really follow the wpg rule so any suggestions? It's also right on a ledge so it WILL get some sunlight and I'm supplementing. Any help will be VERY much appreciated because ill be tackling a 20gallon planted here soon.
