Okay guys...so I already had the best heater discussion and ended up with a heater controller 2 eheim jager 300w heaters and a 300w marine land. Setup was marineland in the center, one jager about 1-1 1/2 feet away from left side (with the thermometer reader on the left wall), and another jager on the right side in the back corner.

I removed my marineland, and moved the left jager into the corner like my right jager. Moved the thermometer to the center. Now my heat has dropped to 28.5c and wont go back up to 29c like it stayed at with all 3 heaters.

Im thinking this has more to do with placement. 2 300w jagers should easily heat a 210. Ill add some pics for you guys. How should I have these heaters set up?

Circulation fan hasn't been on, the bass seem to come up to the top more without it on.





 
I suspect the lack of water flow distributing the heated water? I have seen folks attach horizontally to the back. Still out of the way, but extends across the length of your tank.

You can experiment with that?
 
My two AquaTop 300W heaters have no trouble keeping my 220's temp up at 82 degrees. I definitely don't think you should have any trouble with using two 300W heaters in your setup.

I do think placement can definitely be inproved. With them sitting in the corner like they are, there is not a great amount of water flow around them.

well i moved the heaters outside the filters more towards the center and the temp went down to 28.3C lol. Ill give it a few hours to see what it does
 
horizontal is going to be my next step i guess. Ill go as low as possible so the hot water rises. Ill need some short extension cords though to get the heater deep enough

I find by hanging heaters vertically, they constantly go on and off as heat rises, causing the thermostat to turn them off and on, reducing heater life.
By placing heaters horizontally as heat rises it does not immediately wash over the thermostat, providing a more stable temp flow.

Yes! I'm finding my heater going on and off all the time. I have it placed vertically beneath spray bar but that will quickly change! Thanks
 
Put my heaters horizontal on the bottom. Lets see how that works. Cant even see them from the front.
