temp flux

[jenkins2212]

My temperature is fluctuation from like 75 to 80 from morning until mh come one then it shoots up to 78-80. Is this ok? I have a 300w heater in the 72 and its set on 82 degrees. Can i jack up the temp to keep water warmer at night? Or could that possibly nuke the tank?

What are you using to measure the temperature? Type and brand?

Just a reg thermometer no digital for me!

I don't freak out much about a 2 to maybe a 3 degree temp swing like some but yours is pushing the limit if not exceeding. I would add another heater and set one at 79 and the other at 78

yeah thats what i was thinking. 300w was the biggest aquarium outfitters had out here in athens. but its rated 75-80 gallons. And i guess i have 72+25 so its just not enough. Ill throw one in the sump now.

The 80 degree temp is no big deal, it is the 5 degree swing from 75-80 that can stress the tank. A cheap solution is to add canopy fans that only run when the lights come on... this will typically push the temp down a degree or two.

Good idea as well!

I have the exact temp swing. I purchased an inexpensive hood fan and I would advise you to make the bigger investement and get the ice cap fan. The elcheapo makes more noise than air. I have found that it's cheaper to make the bigger investment than making two investments plus time! Bubba

Or...you could just raise your temperature in the tank to whatever the halides bring it to, then when the halides come on your heater will turn off and the halides will act like a heater, keeping your tank at a more constant temperature! Good luck!

No... you'd just be wasting more energy and end up with a muuuch hotter tank than you want.

Look at the computer fans from NewEgg.com. They typically list the decibels that the fans make, so you can pick a quiet one. If you go with a larger fan (like 120 mm), you can run it at less that 12 volts, still get good airflow, and have dramatically less noise. I have two of the "COOLER MASTER Excalibur 120mm" which I'm running at 6 volts. They are silent and still push more air than the standard 80mm fans.
