Which Tunze should I get

[mycross3]

I have a 250g 25h x 24w x 96l with 12 Moba Frontosa I wanted to buy something to stir the sand up. Which Tunze would you recommend?
Thanks

Keep in mind that you can't get sand in these pumps and expect them to last long, if you just mean lift detritus off the surface of the sand I would suggest a couple 6080's but if you really intend to stir the sand into suspension you need to find another solution, for that I would use a canister filter so the media will prevent debris from entering the motor.

Just to stir up debris on the sand surface you would recommend 6080s? Can I hook this up to a wavemaster?

No wavemakers allowed, they have to run for at least an hour continuosly between off cycles. You could use a timer. This is necessary because a prop has to spin the right way and a clutch is necessary to make this happen and a wavemaker will destroy the clutch system and make the pump overheat in time.
