Need A Heater For 20L Tank

[Titchie]

Hi there, as above really Ive got a 20L corner tank with cherry barbs and danio's in.

It has never had a heater in since new. I put A thermometer in the other week to check the temps as the weather has changed.

It was about 20 c but recently dropped to 17 c. Im thinking I am needing one now especially with the worries of yet another bad winter.

I know all I would need is a 25w heater. But I have a spare 100w heater lying around. It will physically fit. Apart from the extra electric cost would it be ok to use till I get a 25w heater. Also what is a good heater to buy.

Many thanks for any help

100 will be fine however you take the risk of it breaks and gets stuck on the ON/heat position which is the most common, by the time you notice the tank will have boiled. pays yer moneys take your chnaces

How did you decide on those species in your tank? They've got to be feeling cramped!

So whats a good 25 w heater that wont boil my fish, I have a fluval e100 in my other tank but they dont go down to 25w.
I ended up with them due to petsathome's useless advice. This was before we ended up getting hooked on keeping fish. Im now abit wiser. And they get on fine
