If you find out you don't quite have enough light and absolutely can't add more intensity, you can start injecting co2 and that will allow the plants to better utilize the light they have access to. Courtesy of the tropica report that has been floating around... Good read!
Thanks for the info....good to know!!! I've recently thought about dosing w/ co2 - maybe I can start a DIY experiment with that!!! I'll try to post some pics in the next few days. I'm dealing with a slight algae outbreak, I think it's white-hair...just suddenly developed overnight...only on the glass (acrylic) not on the plants - yet!! There is one thing bothering me, and has always seemed to be a problem in all my planted tanks...I have unsettled "tank dust" resting on all my leaves....will co2 injections help that, too? Or should I just keep doing partial water changes until it cleans out?? I stirred things up in there a bit with all the scaping and I just don't know how to keep the dust from settling on my plants. My water is clear - conditions are normal, I just have that extra "dust" on my plants. What am I doing wrong, or what should I be doing!!??
