Temp is tricky. I sleep with the a/c on at night. So in the day with the fan on and a/c off, it is around 28-29C. When I have my a/c on at night, I turn off the fan to minimise evaporation and drastic drop in temp, so it drops to 27C. Is 27C to 29C too big a fluctuation?
Thanks Admiraltian, do you have any suggestions for corals?
Bro barnacle, where to view your tank pics? And what corals you have? I am not running a skimmer. 16L, was told regular wc will do.
