How Many Watt Heater For 5gal

[Animation]

Hey was just wondering how many watts should a heater be for a 5gal tank?

25 W would be fine.. depends on the ambient temp though as you could get away with less or require more.

Just i saw a 50watt on ebay would this be ok?

5w per gallon... so a 25w is fine... a 50w is fine too... it just won't have to 'work' so hard to reach your desired temperature...

Yeah, if it works out cheaper than a 25W...

Unless any of you guys have an old one?
