Wade Posted April 23, 2017 Share Posted April 23, 2017 What's up with my Dragon's Breath? It's turning a nasty yellow.brown color? Link to comment Share on other sites More sharing options...
Sascha D. Posted April 23, 2017 Share Posted April 23, 2017 It's dying. If the tissue has little tiny dots all over it then you've got a sexual episode. If you don't then you're either baking it with too much light or too low nutrients. Link to comment Share on other sites More sharing options...
Wade Posted April 23, 2017 Author Share Posted April 23, 2017 Thanks Sasha. I trimmed back the yellowing pieces and backed the light off a bit. I also noticed the the timer had been switched to outlet on instead of timer on. It's probably been that way since my last water change about two weeks ago so I'm betting it was too much light like you mentioned. It'll probably look better in a few days. Thanks again!

Wade Posted April 23, 2017 Author Share Posted April 23, 2017 I was also thinking of replacing the 6500k fluorescent with an LED grow light. Those seen like the way to go these days. Link to comment Share on other sites More sharing options...
Sascha D. Posted April 24, 2017 Share Posted April 24, 2017 Good idea cutting the dead parts back. Check back in about a week and see if it's recovering. Red and green macroalgae are pretty accommodating when it comes to lighting requirements. I think 3,000K to 6,500K fluorescent is the best, but some people have had success with LED's. Plants grow the best under yellow light, which is optimal for photosynthesis. I use the bulb listed here, about midway down the page. The wattage used will depend on the photo period. I like 8 hours at 40W equivalent or 12 hours at 25W if you're using reverse lighting. Link to comment Share on other sites More sharing options...
Wade Posted April 24, 2017 Author Share Posted April 24, 2017 Yeah I'm running my fuge light at night to equalize pH. I'm not sure what wattage the bulb is. I'll have to check that out. Link to comment Share on other sites More sharing options...
Sascha D. Posted April 24, 2017 Share Posted April 24, 2017 I like the twist CFL bulbs, but some people use the LED's. Most of them are just trying to be fancy, but some are trying to limit equipment heat. CFL and incandescent bulbs run hotter than LED's and add some heat to the water. The heat can help stabilize water temperature when running on a reverse cycle, but might be a problem if you run the display and refugium at the same time. Heat probably isn't an issue for tanks above 100 gallons unless you're running VHO or MH lighting. Otherwise changing the bulb probably won't yield better results.
