This guy is super hardy. I've had it for around 6 months. It took a bit to settle in but is starting to plate out nicely. Fast grower. Acquired it from @REEFTIDE who have great customer service btw. Just wanted to share. I keep the xr15 windexy in the evening. Most of the day I run normal AB+. I added a 6w flexible spotlight LED that has warm and cool white only. I wanted to supplement a fuller spectrum for the acros who probably will appreciate the whites with the fixture I have
