What are your opinions? One 300w or two 150w? 75 gallon tank with about 20 gallon sump. I prefer not to have one heater in my display.

Two 150's will cost you more but it's a lot safer that way.

Cost really isnt an issue. :) however placement of them is. Could i put both on my sump? Maybe at opposite ends. One where the drain is and one where the return is? I really wanna avoid as much equipment in the main display as i can.

they can be right next to each other in a sump. you would want 2 because if one fails you still have one working.

Average Room Temp = 68 degrees F
Desired Water Temp = 78 degrees F
-----------------------------------------
Heating required = 10 degrees F

Tank Size = 75 gallon
Heater size needed = 300  watts i would use one 150 and one 200
 

Average Room Temp = 65 degrees F
Desired Water Temp = 78 degrees F
-----------------------------------------
Heating required = 13 degrees F

Tank Size = 75 gallon
Heater size needed = 350 watts i would use two 200

I have two 250 watts on my 180 (total water volume is 265G). I run LED's so that keeps the heat down, as well as having Ecotech Vortech powerheads and my fish room is not heated. I keep my house at 66-68F and my tank is 78F.

Thanks! That helped. My average room temp is about 70. Ill go with 2 150 heaters to be safe. I will have powerheads that will produce some heat plus 2 pumps in the sump. One mag 9.5 and a mag 7.

They're in my build thread. It's not that time consuming to be completely honest and the cost is SOOOOOOOO much better than buying a premade unit. You also have a lot more control. It just depends on whether or not you think you can do it, etc.
