Blue Z Reef Posted April 10, 2020 Share Posted April 10, 2020 Browning can be a lighting issue, however, there seems to be other issues going on. I see several dead and dying SPS (possible STN/RTN going on). How’s your phosphate/nitrate/ammonia? As Brian said, need more info on your setup in general.

maxicurls Posted April 10, 2020 Share Posted April 10, 2020 Your rocks look very “clean”. This can be a sign of a problem sometimes. Your coral could be starving for nutrients. Check your nitrates. 1 Quote Link to comment Share on other sites More sharing options...
MERKEY Posted April 10, 2020 Share Posted April 10, 2020 How old is your system? Quote Link to comment Share on other sites More sharing options...
pdxmonkeyboy Posted April 10, 2020 Share Posted April 10, 2020 get the dying frags out of there!! In that last picture I am almost certain that frag is getting beat up because it is being stung by the adjacent hammer coral. That is why it looks so hammered. LOL, get it.. hammered.. because like the hammer... ok, back to work. 2 Quote Link to comment Share on other sites More sharing options...
Emerald525 Posted April 11, 2020 Share Posted April 11, 2020 You say you are getting your water tested. Do you not have the ability to do testing on your own ? In my experience I would see brown out with alk swings. Alk is something that should be checked daily when you are having issues. As people will tell you stability is a big factor in sps success. Hanna Alk checkers are a relatively cheap fast and easy way to check alk. This is why acros are so difficult as it is a constant moving target as they grow they have different needs but in my experience it’s the swings of alk not a low number that causes a brown out. I had an alk of 6 in my Red Sea because I didn’t want to dose and was just doing water changes. Had great color things just weren’t growing because they couldn’t make the calcium carbonate skeleton.

Taylorhardy1 Posted April 12, 2020 Share Posted April 12, 2020 The look of some of those acros kinda reminds me of when I caught acro eating flat worms. Especially considering the lack of polyp extension. Any little bite marks on the tissue? Quote Link to comment Share on other sites More sharing options...
goldenbasketreef Posted April 14, 2020 Share Posted April 14, 2020 Reduce light intensity and increasing magnesium to 1400-1450 may be good to try since it is easy to do and will not affect anything else. Increase magnesium by 50ppm a day max Coral will be better utilize Alk and Calcium at higher level of magnesium Next as suggested by maxicurls is to check Nitrate and Phosphate level 1 Quote Link to comment Share on other sites More sharing options...
