Lighting Operating Temperature Question Hey Im new to the hobby and already have a dual 30 inch coralife T-5 setup on my 20 gallon long tank. I know that most marine compact bulbs operate in the 10000K range. My question was what the actinic bulb on my tank does and if a 6500K self ballasted bulb from say walmart would be an ok add on to get some more watts per gallon? Is that operating temperature too low? |
