I have a Coralife T5 HO Dual fixture. It included one 10,000k and one actinic bulb. From my understanding (reading online), actinic bulbs in freshwater tanks are more for aesthetics and less for functionality? I've also read that Coralife brand bulbs aren't the greatest, so I'd likely be replacing these with a different brand whenever I get the chance. So my question is, when replacing the bulbs in this dual fixture, should I bother with actinic? Is there another bulb that would be a better choice?
Some additional information that might assist your answer:
30 gallon planted tank, freshwater
Plants would be rotala, ludwigia, wisteria, water sprite, crypts, s.repens
E.I. dosing for nutrients
DIY CO2 (currently- I'd be replacing the CO2 with pressurized before changing the lights) That's the order I should do, right? I figure that modifying lighting before improving CO2 would be kind of counterproductive, right?
No hood over the tank- I know that this can affect PAR values, but its something that I've just recently started looking into, so I'm not very knowledgeable on this subject. I suppose I could get a PAR meter and try to get a reading with my current bulbs to see where its at before I buy different bulbs? I believe I've been advised that I could go without the actinic, but I've also been told that this light combination is high in only a 30g tank. Just seeking a little clarification.
