Funny thing is Last March when I started my display it was just cycled put in zoas and all kinds of mixed stuff abs everything is doing well. Lost a couple to trial abs error but everything else is fine. So I do this frag tank and nothing wants to live should I turned the ai prime down to 15 percent will see what happens
Yeah in my opinion this has nothing to do with your light and you're solving the wrong problem.
There's something else going on you and we are not noticing.
Are you doing WC's? How many gallons is your Frag Tank?
IME I'd be doing 50-100% water changes every other day on a smaller system with new Frags until everything really stabilizes out.
Did you also cut and frag and add everything at once? Or is this just your QT tank for new frags you buy from stores?
We don't know necessarily the impacts of large amounts of healing or trying to heal coral on a system like that. Not based on anything but just my opinion Healing corals would need a similar nutrient supplement to coral suddenly growing a lot. They're going to ultimately be trying to do the same thing IMO, on top of the decaying rotting zoo from parts you fragged.
Then with coral dying, leeching for decaying zoo, it's a dwindling spiral.
Is it in the same room as your Display?
There's a lot of different factors that can come into play here.
