I own 3 Eheim Everyday Fish Feeders. They are also called air feeders due to a fan used to feed air into the food containter when it activates, to help keep the food fresh. I run a home aquaponics system and so have various tanks to raise fingerlings before they go into my aquaponics tanks. This feeder is the only unit I use for these indoor tanks, though I use a professional US made super-feed feeder in my outdoor grow tank. I highly recommend the Eheim brand and this particular feeder. I will comment on why I recommend this and then some special handling items. First, as I mentioned I have three of these units. Two are run 24/7. These units are reliable, last between 1-2 weeks for feeding capacity (different sized fish supplied by each one), and built very well. The built well comes from the fact that one unit has fallen into the tank twice. Immediate recovery, turn off, then air drying of the internals was sufficient for the unit to operate as good as new. I have used these units for 8 months now without problem. They do come with a sticky backed velcro mount so that they are not prone to fall into the tank. I use those on the one that likes the water. I have had problems with only one unit after about 20 days of first operation where it lost its programming, and upon replacing the batteries it operated for a few days and completely died. This occurred with use out of box, it was not dropped into the water :-) and it was used as recommended. I emailed Eheim, and was advised to return it to their factory or an authorized service center. I returned it to Eheim's Montreal office with a copy of the email and they sent a fixed unit back about 4 weeks later. So, this is why I also recommend the brand. Nothing is perfect, and when I got one lemon out of three -- they fixed it. On using these units: * you must calibrate the feeder so that on an average run it feeds the amount you want -- that is, weigh or measure the amount fed after 10 consecutive runs and then determine what the average is for each feed -- it is a simple mechanical feed mechanism -- this is why it is reliable -- so it is not exact. Your fish are not exact either, they can eat a bit less sometimes. * once you know how much to open the feeder, mark it with a permanent marker -- you need to close it to refill, so this way you will know where to open it back to * you can run the feeder up to 4 different times a day, and each time can have an optional second feed a minute after the first * I grow tilapia, so I feed my fish only what they will completely eat in 2 minutes * the unit is heavy on the side towards the water when it is full -- when doing tank maintenance, remove it so it out of the way (obvious, but I did drop one unit twice) * if your unit goes for a swim: take it out immediately, remove and discard the batteries, keep the battery door off and gently blow dry the unit. Dispose of wet food and clean out the food compartment. Once you are certain everything is DRY, then put fresh batteries in and reprogram the unit. * when using the unit for the first time, allow a week (before you go on vacation) to ensure it is operating fine and feeding the way and amount you want -- don't just set it up the night before you leave -- this way you will see how long your feed lasts also * the feeder does dispense less when it nears empty -- but again, fish adapt * I only use the unit with pellet food - one feeder has a mix of 1/8" and 3/16" pellets, the second feeder has fingerling powder Good luck!
