Oversized heater

[JDFish]

Was looking for a heater from Amazon, Ended up buying an Ehiem 200w. All the other heaters i looked at that were 200w heated aquariums of 120-240l of water. My Ehiem says it heats 300l-400l. My tank is 160 litre but with water probably 120l. Is it ok if my heater is powerful like this?

Its overkill unless you live somewhere quite cold and need something more powerful to heat your tank, but it shouldn't be an issue.

It won't hurt anything, better to have an over rated than underrated heater.
