I could use some guidance choosing heaters and best way to set them up for a IM 170 gallon with 70 gallon sump. I’m guessing that the total water volume would be around 185-200 gallons.
I do have an apex for controlling, but would also like to have an additional separate controller for the heaters.
I was looking at the IM Helio PTC bundles, but it looks like the most powerful heater option is a dual 350 W (total of 700 W) which is suggested for 100-170 gallons, so concerned that would not be enough. I did talk to Brian at IM and he said it would be fine, but I’m not convinced, especially if one dies. They used to make a dual 500 W that would have been perfect, but it looks like that has been discontinued. I suppose I could do two bundles and use 4 heaters and this may be safer than using two higher wattage heaters.
So I can use some other suggestions. My only limit on heaters is that the sump heater would be limited to 14” length, and I would prefer titanium.
