I am installing a 20 gallon refugium for my tank and I am not sure which kind of bulbs will maximize macro algae growth.
I was thinking of picking up a cheap 2' flourescent fixture from Rona.
Thanks

i have seen ppl using those work lights and just clip it on the side
I know over Dads Fuge we put 384w of power compacts over it

Yes Barry any bulb that is lower then 5000K IMO. the 4300K and the 3400K bulbs from Rona or Home depot.

I use 6700K or 7100K PC bulbs for good macroalgae growth.

So 20,000k bulbs are not a good thing?

Hey Jim,
Why not pickup a Hagen Aqua Grow for freshwater, I think the K is around 6500 and for a 2 footer it's gotta be under $20 :idea:

home depot sells a 23 and 27 watt 5700k "phillips daylight" screw in bulb. they are amazing for growing macros, i seriously trippled my growth in my fuge when i switched over.

Yup, Chin Lee & I have also used them with very good results. i have 7 clip-on desk lights using the 27w Phillips Daylight bulbs ($12.99 for 2 @ HD right now) over my 160g fw planted tank & it works great, even for high light plants like red tiger lotus lilies.

Petsmart has some of the aquagro lights running $8 to $20. May not be the cheapest but may be convenient.

How many bulbs would I need to get sufficient light on a 20 gallon fuge. 27 watts doesn't seem like very much light.

i use one 23 watt bulb over my 27 gallon fuge, seems like more than enough light , i also run lite 24/7.
