hey there, I just ordered a 72" x 36" x 24" rimless tank so I'm trying to decide which fixture would work best. I am mostly SPS and i am not a fan of tons of rock work. I also do NOT like the disco ball look of many of the LED I have viewed. i have a giesemann aurora on my 48x24 but it is not going to have enough oomph to light a 3 foot wide tank. sooo.. i have been looking at the 60" giesemann MH and t5 fixtures. i am just really nervous about going with MH as man they can be hot and I keep thinking.. maybe I should be chasing the latest LED technology?? I wasn't really thinking MH until I watched a BRS video lately and man they light was sooo even and so powerful. One phrase stuck with me for sure.. "no amount of phone apps, programming choices or complex light cycles is going to grow coral" Any advice would be greatly appreciated. System will be 300 gallon display.. 130 gallon fuge/sump in basement. thank you!!
