Really need some advise

[undertcontrolj]

I have been struggling to keep zoas in a mainly sps tank. Sps are doing great but it seems that my zoas will just not make it for extended periods of time. I mean you would thunk that if the SPS are doing great that zoas would be too. But sadly this is not the case. Any advise please would be great. Any info I need to provide to help just ask and I will.

Evidence would suggest that zoas don't thrive in the pristine environment that is required to maintain SPS. Now I would argue that, since I have seen zoas thriving in an SPS tank where the SPS was also thriving. You could be having issues with lighting, water flow, or lack of nutrients or a combination of all of the above. Lighting for SPS may be too bright for the zoas, depending on where you are locating the. Water flow may be so high it is forcing the zoas to close up and stay that way. And a lack of the nutrients required for zoa growth (but not desired in an SPS tank) could be starving them out. Can you give us some tank chemistry info, info on lighting, zoa placement, and flow rates please?

Zoas like nutrients in the water, unlike some SPS tanks that are run ZEO/zero nutrient, zoa's don't thrive there.

Where they acclimated properly to the light? got pics ?

I have a heavy sps tank with the more exotic zoas on the bottom (except a couple that love the bright light). My zoas never thrived until I put one of my Vortech slightly above them so as not to blast them but to deliver some nutrients. After that, they really started popping up new heads and look very healthy.

Z's and P's love strong NON-Direct flow as well.

Tagging along. Is 300 gph max output in a 10 gallon too much flow for my zoas? (aquaclear 70 filter)

my frag tank/ holding tank is a 20tal and I'm using 2 hydor #2's and I have some areas not getting enough flow that cyano can build up.

My most consistent problem that keeps zoas from opening up is flow. I consistently have to use rocks to block flow in places so they'll be happy.
