Hello, Sorry no big update just a question.
I've been planning my hood and my stand, which I will be building next week, so look forward to it!!
But I just want to know if I can use the blue marine light (which they have on saltwater tanks) on my freshwater? It looks really cool! I would use a normal white light too.
I can help on this one.
The bluish light bulbs are actinic and intended for Saltwater Marine tanks to help grow corals, etc. Actinic blubs are not bad for freshwater tanks but they tend to make plants look very yellow. Again, it doesn't negatively affect the plants, just the way they look.
I bought a Coralife Aqualight for my 36 gallon that included 1 Daylight bulb & 1 Actinic but due to the yellow appearance of the plants I changed the actinic blub out for a Colormax (pinkish) bulb that suppoosedly helps with plant photosynthesis. Better for the plants & better for the overall look of your plants when viewed under the light & photographed. I still keep the actinic bulb as a backup if one of the others should fail. Hope that helps..............
