so which one did you end up getting ? Curious to hear your thoughts as I am off on Vacation in the near future and have narrowed down my choice between the Eheim and Rena as well.. I have a tank sitter but they won't be feeding the tank. I just want them to pop in infrequently to make sure the tank's contents haven't somehow ended up on the floor
(not that they'd be able to do anything about it other than to throw some towels down..
)
