great looking tank!
I have the same JBJ 28g, question is...
What does your lighting setup look like?
Is it stock with the hood closed?
Is it raised to allow airflow?
And how long do you have your lights on at a time?
Ive had mine going for about 2 months but im sure my temp fluctuation isnt doing my fish any good.
I go with lights on for 6 hours and see a 4 degree increase in temp in those 6 hours.
Here is a thread where I have pictures of my set up... best pic is on the bottom of page 1.

I only have the 24G wish I had the extra 4G...(more like 1.5G useable lol) As you can see I have the sunpod 20in fixture on it, it is a raised fixture, with fans blowing across the top of the water. I go from 77.3 deg to 78.0 deg all day long. Some how look at displacing some of that heat through venting it out! If you have to crack it a bit, to allow it to rid its self of the heat, because 4 degree tem fluctuation ISNT GOOD.... Especially when you can prevent it! Look at surface fans to help displace some of the stagnate heat.
