T5 color progression shots (from LEDs)

IMHO the difference is in the water quality and not in the light

best regards

The frags I had under the Kessil previously (that died or did not grow) would argue with that reasoning. I didn't even do more than a 3G water change in the last few months.

Very nice. What spectrums were both pics taken under?

Yours look nice as well. Both of mine are taken under radium mh lighting (roughly 20k). First one was day one on the sandbed, second is after I moved it to the rocks. The previous owner had it under a reasonably close spectrum. Everything else in his tank looked great. Just this one was browned out

Brought a few frags home to hold for a friend while he moved a tank.

Thought it was pretty surprising how quickly they have colored up. Originally under radions in a 400g tank, they are now under a 4 bulb (no name) T5 with two blue plus, an actinic, and an aquablue special in my 20g QT tank.

From 2-23

From 3-4 (10 days later)

Another note of interest is that I had a Kessil on the QT tank and moved to this T5 light to hopefully eliminate the algae growth. It's dying out nicely.

You managed to get your rack and frag plugs to color up nicely in 10 days as well. I do think one of your frags are doing much better but that aside I think you're just getting a lot more blue in your color.

Lots of different ways to skin a cat but it's clear that the T5 and Radions weren't same spectrum or power output.
