Hi,

I have a 72 Gallon tank with two heaters in the sump. If I try to keep the temp at 72 F (which is about as low as it will go) it is less stable, going from 72 F to @ 74.5 F when the lights are on. Am I better off setting the temp to 75 F which it can hold stable at all times? The aquariums only inhabitants are a small bimaculoides and some red legged hermit crabs for the octopus to eat.

Thanks, Matt

Hi matt

what temp is the tank with the heaters off? A bimac is quite happy down to high 50s low sixties.... Also a fluctuation of a few degrees each day isnt too much of a worry for a intertidal species like a bimac..

They can handle a bit of a daily fluctuation as long as extremes are avoided... :)

Hi,

Thanks for the reply. My aquarium temp without the heaters will go down to 72 F but it rises and falls a few degrees throughout the day. Is that better than a stable 75 F ?

Thanks, Matt

Yep, you are better with a lower temp that fluctuates than a constant high one...3 degrees or so shouldn't irritate the ceph too much! Hey, at least you have a problem with heating, out here, it is all cooling!! :x

Aquarium Temperature

Hi,

Thanks for the reply. I'm going to unplug the heaters and monitor the temp for a while. I am considering a chiller/heater combo to try to maintain a cooler temp.

Thanks, Matt

I am told that a fan on the sump will help significantly with cooling...evaporative cooling can be quite impressive. Is your sump enclosed somehow? If you can leave it open and get some air circulation, that might do the trick. There are also tricks you can do with lights, again allowing air circulation. That's one reason I've converted to a sump...this should bring my temp down to bimac-acceptable levels.

HEH!

Greg, I'd love to be hassled about keeping cool for a change! LOL

A room temp tank here sits at about 60 -65 most of the time :(

For some reason my octo tank in the bedroom wanted to stay at 77-78 without heater. Thats warmer than the saltwater tank in the living room with heater! A cheap small Walmart fan on top keeps it at 70-74 which is better than a constant 78. The only downfall is that you have to do more topoffs due to evaporation.
