I have 2 x 300 watt heaters in my 180 and thay cant keep my tank at temp . My old ebojag's handled my 210 no issue. Want my old heaters back !
Both of these are the same problem. If your heater is isolated due to low flow or encased in gunk, it will heat up and turn itself off before it makes a dent to the rest of the tank. @reefer125g when you say that your heaters can't keep up you mean that they're staying on all night and the temperature is still dropping right?Is the only flow in your sump from the return? I noticed adding a powerhead to the heater container in my sump reduced how often the heater was on.
When was the last time you cleaned your heaters? I cleaned mine a month or so after adding the powerhead and noticed less usage again.
Surface agitation making a difference, yes, definitely. Water rushing through the sump too fast to heat up would defy the laws of physics. Where is the thermal energy produced by the heater going?I’m going for not enough contact time. The water is rushing through th e sump to fast to heat up. Also you’re probably getting a lot of surface agitation which in turn is also releasing heat

That seems odd, maybe you have a malfunctioning heater. Do you have a smarthome plug or Apex with energy monitoring to measure them? I used to have a "150w heater" that was barely pulling 60w. What's the temp of the room?
