Heaters

[Tetraking]

Hi all

I have just been reading in a book that when heating a tank, you need to allow 10 watts per 4.5ltr/1 gallon, the tank i am getting is 101g, if i have worked this out correctly i would need a 1000w heater or 2x 500w heaters, this can't be right, can it? it seems a hell of a lot, so far the biggest heaters i have been able to get a price on are 300w.

lol on my 90g i use 1x 300w heater and that works fine all year round , personnaly its handy 2 throw 2 in and set at same temp so if 1 actually does fail u have the other as a backup

it's 5 watts per gallon. That would make 500 watts for your tank. Still sounds a lot though, but then I only have a 33 gall tank, so anything over that sounds huge to me!

one of the big factors is also how warm/cold you keep your personal living area. If you keep your house temps in the mid 70's year round, then you only have to raise the water a few degrees. Cuts down on the amount of heater required. Of course I like the idea of redundency, so having two slightly inadequate heaters working together gives a safety window to get a replacement if you dont have one on hand. I think it was the visitherm heaters that lay out a watts required per gallon to raise tank "x" degrees, but I couldn't find a copy.

Why not just buy a 300W heater, and run a 200W one beside it, set the 200W to 2degrees lower, this way if the other heater fails, the other will kick in on failure..

This way you do not always have 2 heaters on.

300W should easily be fine for you tank if its in your home.

i like that idea 5teady, i think i might try it that way, my house is always pretty warm, proberly more so in the winter when the missis goes nuts with the central heating
