hi, i had two questions about this heater. i purchaced it online the other day and it was supposed to be submersible, but on the heater is says do not emerse beyond this point? is this heater truely submersible?
also when i put my heater in the tank in order for me to be able to get my tank water to be 78* i need the heater to be set at 72* is there a way to adjust the heater to get it to say 78* when the water is 78*? so i guess what i am saying is the top of my heater is lying about the temperature that it is putting out. is there a way to fix that?
on other heaters you can pull on the adjustment thing and it pops out and spins freely so you can adjust it but i cant seem to do that on this one
You can submerge it no problem. Mine has been submerged for months and its a great heater. I have my heater set to the max and it gives me 80 degrees. Get a thermometer and adjust according to that. Depending on tank size and flow, you may have to set the temp higher to achieve your desired temp
after contacting Fluval they gave me no information what so ever and said that i should send it in and they would fix it or send me a new one.... well that doesnt help to heat my tank at this point so i did a little experimenting and found out how to fix it!
figure out what temp your tank is and unplug your heater. while your heater is unpluged set the temp of your heater to what the tank water is. then wait aprox 15 min and plug your heater back in.
this fixed mine and now my heater is set at 78* and my heater shuts off when my tank reaches 78*
it has been in sync for aprox 8 hours now so im pretty set that it is now fixed
hopefully this works for you and anyone else out there with this problem
