Too much or Too little light for frogspawn

[Scubabum]

Having trouble keeping Frogspawn. I'm losing my second frag. Everything else in tank is doing well. Lighting is Kessil Ap700 set at 32% at peek of day. Just wanted thoughts on my lighting and intensity. Flow is two Mp10's opposite walls on 36inch wide tank set at Reefcrest at 50%

0900-1000 55 Par
1100-1200 83 Par
1300-1600 120 Par
1700-1800 80 Par
1900 50 Par
2000 Lights out.

Param:
Ph 8.2
Sg 1.025
alk 8.4
Calc 460
Mag 1380
Nitrate 5ppm
Phos. 0

Do you have it on the sandbed without any rocks close by that it might bump into when it opens? If not that would be a good start imo

I don't own a Kessil, but if your PAR readings are right, I would say not enough light. My euphyllias prefer a bit more light than that. Last time I checked, my Frog was under 125 PAR at peak light.

Good luck!

It is on the sandbed, with one edge of the frogspawn about 1 inch away from the rock.

Thanks for the advice. I'm going to slowly increase my lighting over the next few weeks and see how things go.

Does it even graze the rock when it's opened? If so that's probably your issue, it cuts them up.

Thanks, I did not know that. I will move it a little further away from the rock.
