So in a few weeks I'll be going on vacation and was wondering what everyone uses for a fish feeder. My fear is the feeder malfunctions and doesn't feed or dumps more than set and wreaks havoc with polluted water. I have 2 tanks..my cichlid tank and my son's 10 gallon w 2 guppies. I've been watching some videos and really not alot out there but what I've seen is the eheim. Curious on what everyone uses. Time away will be roughly 8 days
