Good overall heater

Experience Level: Intermediate


Comments: It's a decent heater and the thermal protection is a plus. The thermostat is not particularly precise. I put two of these in my q tank. One is turned down all the way to 75 F but it keeps turning on when the temp is still 79 F. The other heater is set at 77 and it rarely come on. It's probably best to have an aquacontroller run this thing. Another minor complaint is the rubber suction cups. Is it really that expensive to equip it with a magnetic holder?

Comments: This heater works very well. However I do not use its internal thermostat. It is attached to a Ranco ETC-11000 temp controller which in a reef tank is one of the two ways you should control heaters. The other way is with a Neptune apex. Built in heater controls are notoriously unreliable and inaccurate -- and the Jagers are no different. Crank it all the way up and attach it to a Ranco. You will be happy you did! (PAy attention to the wiring diagrams or find someone who knows how to do it. Super easy.

Comments: I used to use these heaters exclusively years ago as they were super reliable. I bought this one in February and set up a new tank with it about 45 days ago. Today the light was on but no heat - complete failure. My tank temp dropped dangerously low.
