A very good friend of mine runs leds at his store’s sps tanks. He has had great results with the Radion G4’s and it influenced me to get them as well. At that point I was running Hydras with t5’s and my tank was doing good(pic).
With the G4’s I was getting great growth, and green colored sps would do well. Pinks, red on the other hand would struggle. Millies would look horrible, like an almost brown/reddish. I then got an Orphek and ran an office tank(still do) where sps do well and color improved, but still shy of what I had experienced with MH’s.
I started a new sps tank and got only frags this time, some from my other tank and some from other members. Some frags came from a memeber using Radions in his frag tanks, different from his display tank where he runs T-5s. His display tank has been on magazines, it is simply amazing, but the corals from his frag tanks look exactly like mine used to with Radions.
Fast forward a few weeks I started to watch these frags simply take off under the Spectra. Not only they encrust differently with MH’s but the early development of colors on strawberry shortcakes, pink lemonades is what really blew my mind. This tank is a also a newly set up system, less than 2 months old.
I agree with a comment from Sanjay on another heated halide vs led thread here on R2R. “It isnt so much about light quantity, but quality”. He was refering to some sps not growing as fast with led as they did when he ran halides.
