I am finally starting a refugium in the back compartment of my Biocube 29 using an inTank media basket. What type of light is best for this? I only saw a few on Marinedepot.com and they were really expensive! any low cost ideas? please help!
You could use one of those inexpensive lights from Lowe's or Home Depot (the round metal ones) with a daylight bulb in it. You don't need anything fancy to grow algae. Just make sure you rig it up so it doesn't fall into the fuge.
