i use an old wet/dry vac, also makes for a very fast water change.
Just an observation on the battery powered "sucker", they are ok for sumps, if you don't have enough height for a siphon. The problem with the one I use on my fresh water tanks is that if you are trying to get something from on top of your LR the stupid thing looses suction. If you put toomany extensions on it wont suck anything into it. But as for using it for a sump, I think it would be ok. I like using the wet/dry vac better.
Like I need more things to do!
I need to get a wet/dry vac to do water changes and get rid of that stupid giant damsel...LOL

Did you get a new tank?
Just blast a hole through your living room floor and you can lower the collecting container. Time to show who's REALLY dedicated to their tank.
Disclaimer: I don't even have a tank, so I'm probably not going to win the dedication award!
