Any tricks for water temperature

[Salty-Noob]

I do have a heater for my small bio cube tank, but it doesn't seem to be sufficient. I have it at 78 deg but its always jumps up to 80-82

You may want to invest in a higher quality heater. The other thing you could do is use a controller of some sort. They can turn it on and off based on the readings of the temp probe it comes with. They are usually much more accurate. I like the Eheim heaters and the Cobalt Neotherm.

Yeah I think the one I have is crap bug I can't go to big because it won't fit in the back of my tank

Instead of one big one, run two smaller ones.

 

[Salty-Noob]

On opposite ends of the tank

 

[OurReef]

Yup

 

[Salty-Noob]

Sounds good but again I have a skimmer on the other end with limited room to put a new heater

How small is a small bio cube?

 

[Salty-Noob]

I believe it's only a 30 gallon tank

Try an experiment, set it at 76 and see if it still jumps up to 80-82, your problem might not be the heater. You might need to put a small computer fan blowing on the water to help cool.

What kind of lighting do you run? Enclosed or open canopy?

 

[Salty-Noob]

Enclosed the lid on the tank closes down with a glass covering the lights

 

[OurReef]

What kind of lights? Pc, vho, t5?

 

[Salty-Noob]

I have no clue I wish I knew

 

[OurReef]

Can you take a picture and post it up of them? I should be able to tell you.

Heat can come from many sources....pumps, lights, power heads. Maybe turn it down a couple degrees and see if it still jumps.
Getting a controller may be the right decision, but maybe a better quality heater could be the fix too.

 

[OurReef]

Pc lighting, try to get a small fan that you can set on a timer to come on with the lights, I don't think your Heater is the issue.

 

[OurReef]

And I would start saving for a t5 retrofit for that tank.

A small fan??? Well I have three buttons on the tank each with its a own lighting when I hit one of them the lighting is suttle and it seems to kick on some kind of fan
