Nemesis84 April 22, 2011 Share April 22, 2011 I have four 39w T5 bulbs for the 45 gal tank. They are a 6000k midday sun, 11000k aqua blue plus, and two pure actinic 03. All are giesemann bulbs. I am not able to split them so all are either on or off. Got some great Frags last meeting that are doing well, but the colors are not popping as much as I would like. Do you have any recommendations for bulb changes that could give me more color but still be good for coral growth? Thanks, Frank Link to comment Share on other sites More sharing options...
beatle April 22, 2011 Share April 22, 2011 You have a pretty good mix of bulbs. I've heard good things about UVL actinics. They've been the reference standard for fluorescent actinics in VHO for a long time and they now make T5s. You may try replacing one of your 03s with a UVL. How old are your bulbs? Old bulbs don't have the punch that new ones do. You may also try rearranging the bulbs front to back to see if you get more or less pop. Move a bulb to the front to "increase" its output, move to the back to "decrease" it. Link to comment Share on other sites More sharing options...
lowsingle April 22, 2011 Share April 22, 2011 I tried the aqua-pink bulbs from BRK and they look really nice.....maybe replace the midday with that bulb? I like really blue tanks though.......that also gives great color "pop." I now use LEDs and they are the best light I have ever used for color.....especially for LPS, my chalices look insane under them (my SPS grow slow though). cheers, Darren Link to comment Share on other sites More sharing options...
epleeds April 22, 2011 Share April 22, 2011 i love ATI bulbs. I would use two blue plus, one aqua blue special and either one fiji purple or one aqua pink. that would be a nice combo. Link to comment Share on other sites More sharing options...
Nemesis84 April 22, 2011 Author Share April 22, 2011 The bulbs are only 4 months old. I did shift the actinics to the front and it helped a little but still wanted to get some suggestions. Thanks. Link to comment Share on other sites More sharing options...
dakotasreef April 22, 2011 Share April 22, 2011 I second what epleeds said. I think that would be what you are looking for. Link to comment Share on other sites More sharing options...
amos April 22, 2011 Share April 22, 2011 i love ATI bulbs. I would use two blue plus, one aqua blue special and either one fiji purple or one aqua pink. that would be a nice combo. This is a good recommendation and basically what I'm running right now. If you want to stick with giesemann bulbs, their actinic+ bulbs is equivalent (not necessarily identical) to the blue+ ATIs. You could also sub the aqua pink for the straight actinic for even more blue. Jon Link to comment Share on other sites More sharing options...
trockafella April 22, 2011 Share April 22, 2011 i love ATI bulbs. I would use two blue plus, one aqua blue special and either one fiji purple or one aqua pink. that would be a nice combo. I use this combo but the Giessemann version of it, I also have a strip of 1w blue LEDs in the middle, my growth and color are very good.! Link to comment Share on other sites More sharing options...
