Water Temperature

[C.Eymann]

I keep mine at 80-81. I keep my house at 68 during summer and 70 during winter.
I have my reefkeeper set to turn heater on at 79 off at 80,
fan on sump comes on at 81 lights (halides)will shut off if 83 is reached for whatever reason.

Curious, what was the advice?

I'm not sure about the advice given to Thegrun, but my LFS recently told me she keeps all of her tanks between 74-76 F. It blew my mind at the time.

Her reasoning was that higher temps provide a much more accommodating environment for both algae and parasites. I still keep mine around 79-81, but I think that I'm going to be lowering it pretty soon.

The exact temp is less important than having the temp be fairly stable day to day. Reefs off the Florida Keys, especially shallow patch reefs near shore, see pretty big fluctuations in temps from summer highs near 85F to winter lows below 70F.

The reason for the post was just like had been said above my lfs said they keep there's at 72 and that did not seam right so I thought it best to put it tot the experts.

Let the tank drop to 75 in the winter


Can you share with us the reason why around 75? I've always targeted 78-79 and it does well at that. Just wondering why the lower temps

The lower temperatures save energy, there seems to be little if any advantage to keeping the tank warmer than 75.

Mine is very stable at 75-76 year around. One of the advantages of the lower temperature is an increase in dissolved oxygen. If there is a power failure in the summer, at least IMO, that will give me a bigger buffer, in the winter, they can go down to the mid 60's (see Sk8r's post re) without too much harm

77 to 77.5 controlled via apex. It never fluctuates past those points.
