A little update:
Over the past few weeks I have had random bleaching problems going on with chalice, lobos, donuts, and a few lords. I could not figure it out. Well last week I found the cause I believe.
My lifeguard digi thermometer was reading 78-80 but the tank felt alot warmer. So I got my temp probe from downstairs in another tank and my tank was sitting at 83 when the old thermometer said 80. So it was 3 degrees off and sometimes would hit 82 which means 85. Im really ticked I didnt catch this sooner I lost some really nice corals from this.
