Hey so another SPS is biting the dust slowly. It started bleaching a week ago the day before my weekly water change. I did my water change and it paused the bleaching for a few days. Now its bleaching again. Just checked my elements. CAL and MAG are great! 500 (a little high but fine) and 1320. ALK is wayy low at 7.0. I assume this is why the bleaching is slowly happening. pH is 8.0 and all nutrients are currently at 0. There is only about 10% bleaching that has happened on my Acro. The polyps where the bleaching is still have their color.
I've been using Kent Reef Crystals for 3 or 4 months now and have not had any problems with ALK like this. My plan is to do a 7 gallon water change now to try and get everything back to normal..
Any advice or thoughts besides ALK level for why my Acro is bleaching would be great. PS..can silica harm SPS corals? I've tried researching this...minimally.. but haven't found anything. I think my sand bed is leaching silica.
