Bests & Worsts Reviews from Amazon

I use all eheim brand equipments for my fish tank because they are the best. So it was a no brainer to get an eheim feeder. However this thing is a complete disaster for small food/pellets used to feed little fish such as neon tetra etc.. The feeding sliding door is VERY cheap and badly design, it's loose and doesnt allow fine control. So you either dumps no food because the opening is too small or dump a tons of food messing up the water params. Even worse when I went on vacation i set the feeding door to a small size just to be safe since too much food will cause a mini cycle + ammonia spike, which is far worse than feeding lesser amount to the fish for a few days. But when i came back my tank is completely full of food, the cheap sliding door of this feeder gradually opened up on its own while in operation. Luckily I have a very heavily planted tank with a lot of fast grower stem plants that are able to absorb the excess nutrients, so a complete disaster was avoided. The sad part is the feed itself looks to be reliable and solid, just eheim decided to skimp on the most important part of the feed - the sliding door that controls the feeding amount.
