Acan & Zoa Placement Help

[KKGaskin90]

I have some zoas that aren't doing as well as I think they could. The color is dull... I think my lighting is too much for their placement. The ones I have on a frag rack are growing much faster. A few frags became dislodged while I was cleaning (tail end of an algae battle), so I figure now is a good time to relocate. I also have a few Acans I need to find a spot for - 3 frags about 10 heads each. I'm trying to avoid the sand bed since my goby likes to sand-shower anything he can. Here's the zoas:

And here's a FTS with current zoa location circled:

Could be a lot of things. We need to know your parameters to make any conclusion.

Acan & Zoa Placement Help

75g tank. 20g sump. CoralBox D700 Skimmer. ReefBreeder Photon 48 lights. Salifert test kits.

SG: 1.025
Temp: 77
pH: 8.0
Nitrates: 0.2
Phosphates: 0.0
Alk: 7.0
Calcium: 440
Magnesium: 1420

My tank runs too low nutrient for LPS to really thrive. I know it's a placement issue and not a parameters issue as I have some of the same zoas on my frag rack in the same tank (just out of frame to the far left in the FTS) but less intense lighting doing much better.
They aren't doing *terribly*. The ones pictured are closed because I just pulled algae off from around them.

You could try lower intensity on your lighting. I run mainly LPS with same nutrients as you do, but I feed my corals heavily every third day. LRS Reef Frenzy and Rod's food is tasty to coral.

I'd rather not lower intensity as I've got SPS doing well at the current intensity and schedule. I use Rods and Coral Frenzy.
