Whats the max temp that is harmfull for the fish and corals.

I was thinking of putting the heater on a timer with actinics, and have them off during MH hours. Or just set the heater higher so there isnt such a fluctuation

Im sure that i read this somwhere that anything much more than 30 C will start to bleach "live rock" hope this helps

I think it may have already started to do that, i think a bunch of my coraline has turned white, atleast im pretty sure i didnt buy it like that.

Yea, most of my beautiful green and purple coraline is now white.

is it due to the extreme temp changes that is doing this, or just the 80 degree temperatures.
