Aquarium Advice Regular
i see alot of people use gallon but how can you tell which gallon you are using as the us gallon is 3.8 litres and the uk is 4.5 so if you got a 25g tank that is 95litres us and 112.5 uk 17.5 litres diff why cant we all use litres that way everyone knows what size you talking about. tell me what you use and why (if you can)
