E Heater 300W

Q: Just can't seem to adjust the temp. It flashes 77, but the temp stays at 75. Why?

I was having the same problem, though mine was stuck at 74.5--it stayed blue and never got higher, though it was set to 77. I called Hagen, and they said try unplugging it for 10 minutes, then plug it back in to see if that helps. It didn't; they'd said if that was the case it was defective and to return it. Mine was <1 week old.

Q: I just bought this item September of last year and it wont let me adjust the temperature after the initial setting when I first had it

So you move the adjusting orange dial/thingy and doesn't change temp? Some times you have to move it all the way, let it return to the neutral position and the move it again to and so on. If that doesn't work, it may be faulty, contact Fluval, these have good warranty.

Q: does this heater go in the tank

To clear any confusion, the heater is fully submersible to 39 inches. The photos in the instruction showing tank placement are misleading. The ones marked with an X means do not let it hang by the cord and do not just lay it on the bottom of the tank. Rest assured that the unit is sealed well and you are better off fully submerging the unit to prevent water evaporation from negatively affecting the heater.

Q: Will I have "low flow" problems running only sponge filters?

Your air pump running the sponge filters circulate the water. The pump power will determine whether or not there is “low flow.”
