As stated in the title I'm having problem trying to heat my 200. My room temperature is @ 68 degrees, I have a 38 gallon sump in which 2-250 watt stealth heaters are in, the tank remains a constant 75-76 degrees, I would like to hold it at 78. I have the Stealths both set @ 81 and just cranked it up to 83 to see if they could actually get it to and hold at 78. Any idears???

If you are gonna stick with the stealths just keep experimenting with them and cranking them up until you get the desired temp. I think you just need to patient. Maybe a external heater like a hydor would help you get over the hump, but that is my opinion I have never had this problem before.
my garage temp is like below 60 at night, n i have 2x 300w via aqua heaters set at 82.5* n it sits at 82.5" all day long n all night long. never drops. maybe u should try more wattage? this also took about 3-4 days to heat all the way up. the first 2 days it barely hit 76*. maybe u should try waiting
oh yeah, so to keep in reference, i was talking about my 400gal. 2 300watt heaters was enough to keep it steady at 82.
the heaters may be ok........ it could be lack of flow in the sump. I had this problem on a large tank.
try putting the heaters in the tank and see if it stablizes.
if it does it means there is not enough water flowing thru the sump for your heat loss etc....
if thats the case either leave the heaters in the tank or increase flow thru sump.........
if this is not the case add another heater.

Your heaters are currently sensing the temperature only in the sump. You have plenty of wattage for that size of acrylic tank. If you can't increase flow thru the sump then you need to either move the heaters to the tank of get a controller with the temperature probe in the tank.
