hello all, here is my situation, I currently have two 150cm t5 rails each mounted with 1 jbl "marine day" t5 tube and one "marine night" tube (four t5 in total) i had a spare 101cm rail from my old 180l set up that i decided to mod on my 450 and it now sits perfectly in the middle of my tank in between the two larger rails. my question is this, should i mount this little rail with 2 jbl marine blues and have it turn on and off before and after my "main" rails or mount them with one day and one night and have them run with the others? ooooor should i mount them with 2 day t5s for more white light? so yea thats a total of 6 t5s 4 150 cm long ones and two 101 cm hope this makes some sense.....:s these are the lights im using....no reflectors btw.... blues http://trs.thereefshed.com/files/2010/07/LightOn001.jpg whites http://csimg.webmarchand.com/srv/FR...0/C/FFFFFF/url/jbl-solar-ultra-marine-day.jpg any input will be most welcome!!! why did i do all this? well i got that clam i wanted *gulp* she is fully opened and reacts well, but ill wait till december before ill count my victories with it.
