Thank you both. It is acutally a dual 65W bulb fixture that I have over my 29 gallon. I am shooting for closer to 3 WPG
if possible, and a 32 watt bulb with the other 65 watt I have would be perfect. Right now I have 130 watts over the tank which is way too much, but 50% of one bulb is actinic which doesn't affect plants much from what I understand. But I have heard that it possibly helps algae, so I am trying to lower the wattage.
