jtro January 25, 2012 Share January 25, 2012 I have used a old light from my freshwater days for along time now and think its time for replacement. My Refugium is a 20 gallon long tank any suggestions on replacement fixture or bulbs for the Refugium? Thanks Jim Link to comment Share on other sites More sharing options...
onux20 January 25, 2012 Share January 25, 2012 This question comes up a lot. I think any old light fixture and bulb will do. I use a clip on shop light with a regular bulb. Grows chaeto just fine. I'd keep what you have. Ron Link to comment Share on other sites More sharing options...
steveoutlaw January 25, 2012 Share January 25, 2012 See here. http://www.melevsreef.com/fuge_bulb.html Marc Levinson did a great experiment with these fuge bulbs. Very cheap, but effective way to light the fuge. Link to comment Share on other sites More sharing options...
Glenn January 25, 2012 Share January 25, 2012 I used an old 'heat lamp' hood with a 4500-6500K CFL bulb and it worked fine on the chaeto. Link to comment Share on other sites More sharing options...
jtro January 25, 2012 Author Share January 25, 2012 The reason I'm asking is it seem my algae growth in the refugium hes slowed way down and I was thinking its light related. Link to comment Share on other sites More sharing options...
Chad January 25, 2012 Share January 25, 2012 Why do you think it is light related? Change the bulb? Link to comment Share on other sites More sharing options...

Are you periodically harvesting? Maybe your system is in balance and there are no more nutrients to support further growth? Link to comment Share on other sites More sharing options...
jtro January 25, 2012 Author Share January 25, 2012 Yes I am harvesting haven't really changed anything just used to have more growth then I do now. Link to comment Share on other sites More sharing options...
smallreef January 25, 2012 Share January 25, 2012 could be the bulb,especially if its that old,, could also be that your tank isnt as nutrient rich as it was before? Link to comment Share on other sites More sharing options...
