Problem Solved?

My reefer has been up for some time now, and it's had some issues regarding brown algae bloom which I have since handled dosing NoPox. However, I just realized recently my Apex thermometer was not fully submerged and was covered in slime and buildup - the reason I realized this is because I bought 2 cheapo thermometers for tank side and sump side and it indicated that my water temperature was 81.5 degrees - this was at the valley of my temperature curve, so my tank was probably reaching as high as 83 degrees. I am wondering if this is why my inverts and corals have ultimately died off. I am not sure that 83 degrees would be warm enough to cause this type of loss tho?

My other parameters are all in check, recent ICP test also confirmed this.

Were you measuring PH during this time? Higher temperatures would lower PH, so it may have also dipped lower than expected.

My pH was monitored during this time as well, it was between 8.3 and 8.55. I guess that's a little high?

Technically but higher temps should make it lower. So something else was probably also wrong.

Well, I am not certain the issue is resolved, but my guess was the temperature - any other ideas / thoughts?
