Air Pumps

[mak]

I have found an air pump I want to buy for my 180 litre aquarium, it says on the box 0-200 litres. Does this mean it is ok for my 180 litre tank?

An air pump rated at 0-200 litres will certainly be ok for your 180. With air pumps it really doesn't matter on the rating as the air/oxygen is absorbed into the water at the surface so as long as there is agitation (movement) on the surface your fish will be ok.
Any air flow/bubbles is a bonus.
