What Size Heater?

[ceilidhgirl]

hey everyone

i'm a newbie to this and i'm looking at getting a tank which is around the 20 gallon mark (23 uk gallons to be exact)

it will come with a filter but not a heater.

is there a watts per gallon ratio or something like that to make sure i get the right type / size of heater for the size of my tank?

many thanks for any advice in advance

There is, ill have a look...

3 - 5 watts per gallon

So 69 - 115W for you.

So 75w or 100w heater you will need.

Id go 100W

my tank is around the same size and it came with a 200w heater

Depends on its location really... if its in a cold room you will need a larger unit than if your room is central heated 24/7 ... generally Id say 100W
