Hey folks What's your GO-TO Heater? I've been using eheim jager heaters since day one and I am not happy with the results. Right now my tank is sitting at 77.6 degrees when its suppose to be at 80.5 degrees. 40 breeder+20 sump+14 gallon satellite frag tank all plumbed together. I'm gonna clean the return pumps today to make sure this cold water isn't due to a slow return rate. The house temperature is probably 58 degrees at its coldest time of the day for NOW. Will get colder i'm sure I have TWO 150watt heaters in my sump and it seems they are struggling to hold the temperature above 80. I've had to replace two eheim jagers since 2014. Which heaters do you think are the best?
