Tank heater w finnex 810m question

[Kingin]

I have a 65 gallon tank was running 2x 150 watt aqueon glass heaters. I recently got a great deal on some eheim jäger heaters but I only have 1x 150 watt, 2 x 200 watts and 2 x 300 watts. Would it be ok to put 1x 150 watt and 1x 200 watt heater in same 65 gallon tank connected together to a finnex 810m controller?? The eheim Jagger's are used but only paid about 6 bucks each in a bulk lot off eBay.

Thanks in advance
