refugium lighting question

Postby DDD33 on Fri Feb 15, 2013 2:02 pm

I have a 20 gal refugium that has some plants in it and I haven't been getting much for growth since changing bulbs. Without really putting much thought into things I purchased 2 - 14K bulbs (30" T5), since they were what was available at store. Then I got thinking that my planted freshwater tank uses 6700K bulbs, should I be using same bulbs for saltwater plants?

dude i have the same problem i cant get my plants to grow at all so i bought a plant light hopeing it wil help my plants grow more.. but from what i have heard that if your plants are growning alot you have a nutriant problem.. you want them to grow but you want them to grow slow if you dont have a problem..

I always used a 6.5k fluorescent bulb that was at least a 75w equivalent on and eight hour timer. It worked well and consumed little electricity.
