Kessil AP700 & Clam's

[oldpaddy]

Very happy under an AP700

Bump and hijack!

I added two clams, a maxima and a derasa a few days ago. I placed them near the middle, front bottom on some rubble. The maxima moved 7-10" overnight and the derasa moved about an inch. They haven't moved since. I'm wondering how they're going to like being at the bottom of the tank and whether I should move them up higher. I really wish I had a par meter.
Anyone have any thoughts?

I have 3x kessil ap700 set to 100% at their peak, but I set them to 7 day acclimation mode with a 30% start. They're 7" over a 225gal (24w 30h 60l") established tank.

Thanks
