My wife has a 10g @ her office work place. Normal weekend leaves her away from office.
We just set up this feeder last week and quite happy with it's function. She has opted to use it all the time, and just keep an eye on it to be sure it is working properly. Need to keep these feeders away from bubbling water, as the mist could moisten the flakes and hinder the release when the little cog brings the does by the opening.
She just puts a pinch in each section, just as she would in the usual mannor of daily feeding.
She has
4 fancy guppies 1m/3fm
1 Red Tail Shark
2 Baby Bumble Bee's
2 cat fish
We're believers in the 'less is more' feeding philosophy
Lifeguard Automatic Fish Feeder & Hopper. Cost: ~$45 though Aquarium Guyz
We don't use the hopper, but keep it in case we ever need to auto-feed a larger tank. This feeder is AC powered which we like, and will feed up to 14 days without the hopper.
It can feed 1,2,3, or 4 times per day.
We'll probably get one for our home tank too - for an away trip to deliver some horses from Vermont to Iowa in April.
