Aquarium Co-Op Auto Feeder

After I watched the video and was able to set it up properly, the feeder worked great. I took off one star off because the instructions that come with it are difficult to understand. I strongly recommend the instruction video on the website which is excellent.

Love how easy to use it is and it is pretty water resistant by the way. However if you have a thicker rimmed tank like the Petco 75 gallon tank I highly recommend using super glue, the small lip on the rim makes this thing impossible to fit. After seven months of me having it on, it somehow fell into my tank while I was away and I came home to a dead community tank. I like this product way too much though because it gets my fish used to a spot on feeding time so I ended up super gluing it to the rim above the small lip. It is firm and won’t fall in now, & you simply pop it off from the rotating part when it comes to charging or refilling it with food. And surprisingly the water didn’t seem to affect it, it works perfectly fine till this date. On the bright side it got me away from my starter tank & gave me the opportunity to order a school of Celestial Pearl Danios! They should be coming in this week, super soaked to start a new community with the knowledge I have now thanks to the Co-Op Team!

I tested this product on one fish tank initially, and it worked so well that I bought two more for my other tanks. To me, the features that made it excellent to use is the adjustability of the feeding times and battery life. As stated in the product review, and in multiple YouTube videos, is that some adjustments may need to be made to the opening (e.g., adding tape) to better control some fish foods. I have had trouble dialing in the opening gate and tape fish with flake food. Particularly larger mixed-sized flakes where the inconsistency of the food size itself is the issue.
I currently use the Magic Small Fish Feed and Community Pellets in this feeder and have noticed a much easier time in dialing in the feeding amount. I would love to see an Aquarium Co-op opening replacement specifically for these products to better tune the feeding amount without having to use tape.

These are the best auto feeders I’ve found. I have 9 of them. You have to experiment with the settings to get the right amount of volume which will vary based on the specific food. You may also need to use tape to lessen the volume at even the lowest setting for finer foods but that’s not a big deal for me. Obviously, I recommend.

I have 5 of this specific model and rely on them when I'm out of town for up to a week at a time. I fed once daily with 1 or 2 drum rotations, but the setting is capable of 4 drum rotations. Easy to set up: set it them forget it.

3 of us tried programming it. Never rotated. I will be calling shortly for a credit.

The automatic feeder is easy to set up. Instructions were very clear. I was away for two weeks and came back to my happy healthy community tank.

I’ve been using this for several weeks. I recently was gone for five days on vacation and came back to fish that were fat and happy. This feeder has kept perfect time since I got it. I removed one star because the smallest opening is still quite large if you are feeder only a few fish and/or small food. In my case, I am feeding about a dozen guppies the magic nano feed. I had to use tape to make the opening very small. Being able to have finer adjustments on the opening size would be nice, but overall this is a great feeder!

I have used mine for a week. It works very well.

Basic setup is very simple, tested it a few days while I was at home so I knew it would feed while I was away. Worked as advertised
