I would get a second thermometer and double check your temp readings. I had a customer recently his tank was running 82-84 consistently and all his rics receded away.
Not sure what kind you use, but have you ever looked at the digital ones at the LFS? They almost all have a different reading on the shelf. I personally like the old school variety thermometers...when you look at those on the LFS shelf they all have the same reading.
Also be sure you are getting the highest reading of the day....for me it is usually around 5-6 pm these days.
I have an old school manual thermomter downstairs. I will throw it in the tank today and check it several times throughout the day and see what I get. Currently I rely on my Reef Keeper and associated probe and two 400W Ebo Jager heaters to keep my temp stable. One thingof interets maybe that myy sump is in the basement and it always stays cool down their. The tank is on the main floor and the water obviously circulates but I wonder if its warmer upstairs or if the Reef Keeper is out of wack. I guess I will find out today. I will post my temp readings.
