Hi, I've just changed from a 12 litre tank to a 72 litre tank for my 8 small fish. Now the filter looks really small, possibly inadequate for the bigger tank. Do I need a bigger filter? At the very least I need a longer air tube on the filter so it can sit deeper in the tank. Any advice? Thanks
Do I need a bigger filter ?

You will probably find the filter is too small for the bigger tank as you need the filter to cause a flow throughout the water and filter the entire volume.
You’ll want a filter with around a 4.5x turnover, you should be able to adjust the flow to suit your tank and fish.
On a plus note you can use the media (sponges etc) in your current filter and put it in the new filter and it will support your current bioload (fish) as the bacteria have already established.

Well done on the upgrade. I'm sure your fish will enjoy the extra space.

You'll need a filter that has a minimum flow-rate of 300L/h (litres per hour) such as the Fluval U2 filter, TetraTec Internal IN600 plus, Eheim Pick Up 200, AquaEl ASAP 300, and many more.
