Great unit for Large Tank By Wayde on 7/23/2014Wayde would recommend this product to a friendPeople are rating this product down to 1 start. Why? Because they did not do their research and bought a unit that's for a LARGE tank. That is a shame because this unit functions very well as designed. You can set how many twists the dual screws rotate individually per feeding cycle. On my large tank this is the first feeder I've found that can actually last a whole week without needing to be refilled.
Its a great unit.
Reliable But Difficult To Use By Shawn on 4/16/2014Shawn wouldn't recommend this product to a friendThis unit works pretty much as stated by Eheim. I can't fault them for the unit itself. Unfortunately the minimum amount of food it dispenses is close to a tablespoon per feeding which isn't an appropriate amount for mid to small sized tanks. It is also a bit difficult to program as well.
If there were more control over the amount of food dispensed I would purchase this unit again.
Good unit for large tank By JTG on 4/3/2014JTG would recommend this product to a friendI have used a variety of feeding systems - most have proven very difficult to manage, especially getting to a consistent and appropriate amount of food dispensed. This unit is a material step up in that regard - consistent amount without having to complete a complete recalibration every time I reload the unit with food. That said, I doubt this unit would be appropriate for a smaller tank. In my case I have a 215 gallon show tank that is moderately populated - and it works well. but the minimum amount of food might be too much for a small (say <100 gallon) tank.
An update to fix problem By Big C on 11/30/2011Big C wouldn't recommend this product to a friendI tried numerous things to decrease the volume of food being fed per revolution and, with the help of a friend, figured something out. We cut pieces of thin plastic (really anything that is semi-stiff and cut-able will work) to fit flat at the bottom of the bin, just on top of the corkscrew mechanism. The spillage around the edges of this "blockage" is quite a bit less than a regular revolution without the "blockage". So now I can up the feeding by adding revolutions but one seems plenty for my 75g reef. Hope this helps. I thought the thing was pretty easy to program myself. You get up to 3 feedings per side and can set the exact time for each feeding and how many revolutions the corkscrew makes per feeding.
Sucks By Justin on 11/13/2011Justin wouldn't recommend this product to a friendLike Big C said, the portions are way too much (even on a sparely populated 90g). On top of that, the thing is a pain in the butt to program. Look elsewhere.
It works but WAY overfeeds By Big C on 10/25/2011Big C wouldn't recommend this product to a friendThe feeder works but the portion size is way too much unless you have a large tank or feed alot. Otherwise you will be fighting nutrient problems continually. I contacted Eheim about this and their only reply was that you can only change the number of feedings and not the portion size. They said I should purchase the Everyday feeder! So if you have to buy an Eheim feeder, don't get this one unless you feed a lot of food!
