hi maybe im being thick but im looking at ( soooooon i hope!) buying a juwel rio 300 states on website volume 300 litres only when using the aquarium calculator on this forum it comes out at 382 litres or 80 odd uk gallons. now i know it comes with a built in internal filter ( which will be binned) but are they really big enough to take up 80 litres of space i know plants gravel etc will take up some but surely not 82 litres??
