I think I’ll do some testing today. I sent away an ICP last Monday, but probably won’t be seeing the results until next week. It’s on the sand bed, so I believe it is under 100 PAR, ( assumption, can’t give a real value that is bonafide). I kinda think it might be something else, maybe parameter related. There is another tear, doubt it was a bite from the fishes. Any invertebrates that would do harm? What water parameters are Trachyphyllia most sensitive to? My magnesium is over 1500, haven’t been able to drop it, done 3 water changes in the course of 2 weeks comprising a 50% change in total water volume. My skimmate foam has been over the top literally, and that’s been my fault to over feeding corals and filter feeders. Normally a 10% weekly water change is my weekend chore. Been using a Red Sea 4 pump doser for 3 weeks. Last Sundays tests:
Calcium 400
Magnesium 1510
Alk 10.304 dkh
I’m Sure my calcium is on the rise, I’ll know later, my target value I’d like it to hold would be around 460. Just going to get it there slowly, but I think my magnesium numbers are never going to drop, and maybe that’s ok. I’ve read a few threads on people keeping it over 1500 for good reason. Idk, I probably messed something up, but everything else seems to be doing well.
