Hey everyone,
So I have gotten a few acropora frags and they had been doing great for about a week. Then they started to in a way brown out and get their tips burned. So I tested my alkalinity over 24 hours and it barely changed from 7.8 to 8. I also tested my no3 and po4. They were 10 and 124ppb so I dosed Lanthinum chloride to bring it down to 34ppb. Could I have dropped my po4 too fast and the corals then stripped some tissue. They also look "skinny" less plump than when I got them. Polyp extension is also a minimum.
I am running 2 compact orpheks and 4 or120 blues/uv on a standard 90 gallon I turned the orpheks from about 40 percent max to about 90 percent. Could that also be the issue?
Alk 7.8-8.2
Cal. 450
Mag. 1350-1400
Po4 .1
No3 5-10
90 gallon 48×18x20.
2 compact orpheks
4 or120
Skimmer
Brs 2 part with tropic marin trace
refugium (opposite schedule)
I don't know what could have happened.
