My tank has been running for a little over a year. I started with all small pieces and frags but I did have a crash a few months in that wiped out nearly all my SPS. I restarted with acros about seven months ago with all new tiny frags and a few of my pieces that survive the crash.
I started with three G2 pros and a few months ago added a fourth. Shortly after I added to T5's not because I was unhappy with the color or growth but because I'm a tinkerer and I'd like to squeeze all I can out of things. If I'm being honest I haven't really noticed a difference in color or growth since adding the T5's although the visual appearance of the tank looks much more well lit which I'm not sure I prefer.
This was 13 months ago...
This was 2 months after my crash shortly before adding new small frags (February)..
Three months later after adding the fourth radios. Noticed a huge difference after this (May)
End of May
Added t5 in June
End of July
iPhone video in August
Currently going through an all funk because of 2 months of bad Hanna all reagent. So yet another setback. During the year I had 1 major sps crash, a major funk, and 2 minor funks where I had issues with stn and poor health but tank is still kicking. Looks like crap to my eyes now but I've had a few reefers come over recently for frags and they think it looks amazing lol.
I'd be happy to post progression shots too.
My last tank was halide with blue led. My take on it is growth is about even for me, although my new tank is 120 gal and my last was 30. Color was about 10-15% better with the halide but by no means is my tank colorless.
Hope this helps...
