Hi Nick and Paul,
Just had my aquarium heater in for the first time last night. I had it on max (32c) and it heated the water up a bit - enough to make the hoses noticeably more pliable. What temp do you reckon your water is at after an overnight heat (and what size tank have you got)? Have you got a neon light on your heater (as it says there is a neon light in the instructions - I haven't).
The water was warmer, but nowhere near 32c in my 500l tank. I had it suspended vertically in the tank about 3 inches off the bottom - how do you have yours?
Cheers.
Hi Carl.
My 1000w aquarium heater usually brings the 500, or so, litres of water up to about 24 to 26ºC in 8 hours. I have a second 1000w heater that I use if I require more heat for any reason.
I place the heat on the bottom of the tank with the two plstic surrounds you see in the pictures preventing any direct contact with the tank.
And, yes, my heater has a red light to indicate that the power is on, and that the thermostat hasn't intervened.
