lightning question

[jorge0912]

i know i have asked this question a couple of times but i need help .i currently have to black boxes on my 75 gallon reef tank but i want something better that would help me grow coral... radions are a bit expensive but maybe i can afford two xr15s but will two of them be enough for my 75 gallon ? i can also afford hydras but does it grow coral good.... a friend recommended adding just two t5s purple plus for the spectrum and that i should hold on the more expensive leds that should fix my porblem and it should help grow coral but i need help on which one would help for now ...
my tank is a mix of soft corals and lps thinking of making a tank thread ... but don't know how

Buying corals...then lighting.... not a good sequence of events. Just sayin'

I HAD MY reef for about 4 years now and going never had a problem with coral health or anything just wanting a bit of faster growth maybe a better led i have always researched about a coral before buying also had a par meter to see where the coral would be suited best for the placement... never would i buy coral then lighting... that's would just be irresponsible...
