I am planning on setting up a 33g tank and am going to be putting plants into it. Now, the light that I am going to be getting comes with a 10,000K bulb and one actinic bulb. I ordered a 6,7k bulb for the fixture, but my question is, can i keep the actinic bulb in there for the blue effect in the tank, or should I take it out and use the 6,7K bulb?

Thanks.

I took mine out for the 6700K bulb, left the 10K but the actinic doesnt do much for plant growth at all that I have experienced even using Co2.

agreed, actinic bulbs are good for growing saltwater corals and freshwater algae. The 6700k will give you the best plant growth while the 10000k will give you good color.

Ok thanks. I didn't think the actinic bulb would do anything to the tank, but I thought I would ask just in case. So I will leave the 10,000K bulb in and then I will replace the actinic bulb with the 6,700 K bulb that I ordered.

WhiteDevil, your plants are growing great under that light. I hope that I can grow good plants under mine.

No use for plants and can actually benefit red algaes such as bba.In short term use it will be ok till you can replace it.

t5ho's and diy Co2. every now and then i toss some potassium sulfate powder in to kick the growth a bit.
