Hi, what exact internal diameter hose (not length) would I require to extend this, so it reaches outside.. 👍

Disregard my last answer of 12mm id. I thought it was for the fluval pro vac. A 12mm id will work but will need a hose clamp to secure it tightly. You need 8mm id hose for this one. Think i paid about £15 for 5 meters.

Is the suction strong enough to pick up most waste? Have only ever used electric.

Yes flow rate is adjustable and turned right up it will suck up the gravel itself. I find about half flow best as it picks up the waste but not the gravel. as it is a siphon you need to drain it into a bucket below water level and then return it to the tank or replace with new water unlike some electric units that allow you to clean the gravel and return it straight to the tank. One bucket of water gives about 90 seconds of cleaning

It says this will work with sand is this true?

Works well on fine gravel however it is quite powerful once going and I think it would suck the sand up to be honest.

is this suitable for 240 litre tank?

Yes, but It's narrow. (Fluval could improve on the design by making a funnel attachment for the end to allow for a wider area of suction). With the provided extension, depth is not an issue. However, I expect there are better alternatives to this model for 240 litre tanks.
