Bleaching or growth

[glagunda]

Certain spots have light coloration on the tips. Is it bleaching or growing. All other corals are perfectly fine. Ca 435 alk 7.8 mg 1460 Phosphate and nitrate detectable but not high.

Second images looks like a healthy acropora. Do you know type? Under what lighting type? Can you post an image under white/day lighting?

Honestly can't remember. It's currently under 300 watt cheap led lighting. It's definitely growing though. This is what it looks like when I got them

Just noticed the light coloration. Just got me worried a bit. I bleached a garf bonsai when I had a alk spoke to 11

I believe the common name is Frogskin Acropora. It might be a Tortuosa, but I would have to look that up. I had a nice colony, that grow very quickly, so I would not be surprised if that is new growth. Mine was about 5 inches below a MH 150 watts. Looks like it's in a frag rack, if it lightens any more move it down.
