![]() how knows what this is,ore what is happening.
about 1/2 of my coral show a white rim on there base, and it appears like base growth is moving away / eaten away. also my Monty cap shows some spots in the middle, my yellow slimmer partly went brown (the picture is not the best, but you can se the left is not the same as the right) would this be a bug, ? I removed several coral and went over it with a magnef. glass, and nothing there, and I have bin really, really precise on this. could it also be chem. warfare between coral? and this is how thy react? I have some mushrooms (not a lot) and one leather coral, about 30% is LPS and the rest SPS most SPS are big frag size (3 to 4 inches) and have maybe 4 big colony’s of 5 to 8 inches ![]() ![]() ![]() ![]() ![]() ![]() |

![]() From your pics, it could be warfare (corals too close together) and / or shading. I see a couple frags sitting in the shade of rocks.

![]() ok,
water par. Cal. 500 (I know, I know,) I'm gust waiting to go down a bit, I made one batch of my bailing to strong KH generally kept at a steady 8 to 8.5 mag: 1400 steady phos:0 nitrate, nitrite, amonia all 0.00 so from water quallety point of vew, yes there have bin some swings the last 3 weeks in the KH and CAL. becouse I did mix the bailing wrong, and found out later I did start with ZEOVIT, but this is sinds 10 days now, and I can only se improvements in mostly all coral (growth tips and PE) the white base and discolloring is something that has started about 3 months ago. Lights I know that the phoenix bulbs where 1 year last month (my LED unit should be running the upcomming 2 week, I have waited with the bulbs becouse of the LED's that go over it. chem ware: I dont know, corals are far appart (it is a 350 gal tank !!) and only have a few mushrooms and a lether coral (and about 30% LPS) BUGS: as mentioned, I cant find any, and I have bin locking for a few weeks, even with a microscope nothing there I did a Salifert Flatworm treatment on the entire tank about 4 weeks ago (5 times in 15 days) as it has proven to kill a fair bit of bugs, and asI could not se anything, I did it gust in case there was, and I missed them. furthermore there is ROX runnin (1.5 cup, of what I replace 1/2 cup each 2 weeks water change I do each 2 weeks 40 gallon -- this on the opposit week of the carbon change than there is 1.5 cup of GFO that I change each month overall as there have bin some slight changes, lights are on there replacment, water par. swings I think it is gust that the corals ar not 100% happy, but wanted to se if there is somone that could se potential bugs that I have missed. so more ore less if no one sees simptoms of bugs, it must be the overall things that happened, if thy think thy se damage from a bug, than I can lock spesiffic for it. as mentioned, I do se lots of posetive things happening with the zeo I ad |

![]() I had something similar happen to all my SPS and I found it to be a combo of CA/ALK swings paired with my biopellets. Doug (Fishytime) did a really good job of explaining it, can't quite remember but I removed my pellets and have never looked back. I know your not running pellets but CA/ALK swings leading to pH swings can wreck some major havoc.
The problem with STN is once it starts and the coral is immuno-compromised it's a very slippery slope towards death. I would personally frag all the dying coral and frag epoxy your tank with some new frags. |

![]() Hows the temperature.
The summer weather raised my tank to 84F and I lost a couple corals recently. SPS and Zoas.

I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds. ![]() |
