Randy, thanks for joining in!!
In regards to acclimation I just drip into a bucket of water. No light and no heat. Room temp is generally 75-76F. I would find it hard to believe acclimation is the problem since it has taken months for the decline of most of my coral. The only things that died within a few days were 2 hammers. Everything else was opening up fine and seemed ok for a few weeks before starting to decline.
As for nitrates I just have chaeto in the sump. It grows like crazy. No algae really in the tank save a small amount of Valonia that I can't seem to get rid of.
As for flow I have 2 MP10s running on Ecosmart at around 50-60% of max.
I perform a 10-15% water change every week generally though I have skipped some weeks here or there. I run at 1.025SG using red sea coral pro. With the tiny amount of coral actually pulling nutrients in the tank I would think that would be enough to replenish trace elements. Maybe not? I have talked to a member here in chat who has a beautiful zoa tank and hasn't done a water change in over a year. I have heard zoas like dirty water... But then this wouldn't account for the death of the trumpet, fauvia, acan, sympodium, or some of the others.
I think my issue is a combo of light and maybe iodine... But I don't know if it's too much or too little light. I talked to a guy who has beautiful coral and he runs his single Sol pod at 95% over a 30. Surely then running 2 pods
at 40% over a 60 at 14" above the water isn't too much light? But I don't know.
