I tend to stay out of these threads as there is a lot of "well I bought these so they are the most awesomenest".
For me, I only use cree bulbs, I only do DIY to save on the crazy markup, and i think if you have patience, you can have an amazing sps tank with leds.
i wish i knew how to build my own and had time to do it..... would have been cheaper i payed $550 for the firstpair of ai then $650 for the second pair when i got a bigger tank on the up sidehave a spare controller
So with the 2 new 120W LED I've been slowly ramping up both the blues and whites to acclimate the corals. Should I go to 100% or where's the threshold?
