blueray Posted March 11, 2008 Share Posted March 11, 2008 Hi All, I have a 3ft T5 2X21W blue 2X21W white, 3ft 2XPL24W blue/white. Can I change all the T5 to white and increase the W? so that I can change the PL to all blue. is it advisable? my next question is does the corals need blue light or which is better, blue or white? thanks for the advice.

SRC Member vt_snowman87 Posted March 11, 2008 SRC Member Share Posted March 11, 2008 by the way, blue tubes is just for the luminous effect in corals.. if possible u should try ATI's series, true actinics really brings out the colours better..

Achilles Tang Posted March 11, 2008 Share Posted March 11, 2008 There are pinned up threads on lighting in the New to the Hobby forum. Some in the Advanced forum. Do a google on lighting for reef aqyariums... its a complex subject. Different corals, plants, clams etc need diff light with diff saturation, intensity, photoperiod, and spectrum wavelengths. Its not as simplistic as just get this or get that. You have to study and evaluate your livestock vs your setup vs your budget. Sometimes, you may even need to upgrade other equipment like your chiller to cope with extra heat. Quote Link to comment Share on other sites More sharing options...
SRC Member vt_snowman87 Posted March 11, 2008 SRC Member Share Posted March 11, 2008 ^ absolutely true.. different colour temperature (the different K) will have different growth effects on ur corals as well.. those threads are very useful, i burnt midnight oil to digest and understand the interesting facts.. happy reefing blueray, congrats on finding this site, its super infomative..

blueray Posted March 11, 2008 Author Share Posted March 11, 2008 by the way, I found out that my existing light is low output. I intend to get a MH in 2 weeks time to set the proper lighting issue right. Quote Link to comment Share on other sites More sharing options...
RockyBoy Posted March 13, 2008 Share Posted March 13, 2008 Use MH and supplement with T5. Won't go wrong. With MH, you need chiller. Quote Member of : UEN: T08SS0098FMASS in Facebook Reefing in LED Link to comment Share on other sites More sharing options...
