Product Questions

Can this feeder be programed by itself without the apex. I plan on buying the apex soon I just need an auto feeder sooner than I have the funds for the apex.
Question by: Jimbo on May 8, 2014 4:49:00 PM
Hi Jimbo,
It cannot, it requires the Apex system in order to operate.

Hello,I have the apex lite,if I buy this apex AFS feeding system,what else do I need to buy to make it work ? Or is it a plug and play ? Thank you kevin
Question by: Kevin on Jul 31, 2014 4:56:00 AM
Hi Kevin,
If you already have an Apex system all you need is the AFS system :)

I actually have two questions.

1. I see there is a clamp for mounting the feeder on the tank. Will this clamp work on rimmed tanks?

2. How would the installation work if you have a glass top or screen on your aquarium?
Question by: Joel on Jan 25, 2016 3:00:00 PM
Great question!
The clamp can work on rims up to 2" thick without issue. If there is a glass top the feeder of course will not work however with a screen top you can cut a section for feeding or if the holes are large enough allow the food to fall through. Feel free to let us know if you have any further questions!

What is the volume of food that can be held in the unit?
Question by: Flagg37 on Jun 15, 2016 10:50:00 PM
Great question!
This will hold just over 100mL of food. Feel free to let us know if you have any further questions!

I have the Apex Jr. and I am aware of its 5 module limit. Does the AFS count towards my module limit?
Question by: Jordo on Aug 19, 2014 7:15:00 AM
Hi Jordo,

Any module plugged into the Apex counts towards the limit of 5. This counts the display and expansion outlets like the EB4 and EB8 as well. If you are maxed out at 4 modules you can always stop using the display unit and use your phone or computer to control the Apex to open up a spot for one more module.

Hope this helps.
Have a great day :)

  • Been using over a year and love it By IQABOVE50to-operate on 9/22/2016

    I find the complaints laughable. Yeah, it makes a little noise for all of 30 seconds it operates -check.
    Slide the reservoir straight out to remove and refill, or slide it out with sideways tension to spill the food all in your tank.
    I have never spilled any food in my tank, and just actually pay attention to how I open it.
    It''s like the old argument to girls, pay attention before you sit, or put the seat down, but first pay attention. This is a good feeder, doing what it should.
  • Does the job By Kevin on 9/14/2016

    Ok not perfect but I needed something to feed the fish when I'm not home. It's loud but not a big deal.
  • Junk By Chad on 8/28/2016

    I don't understand why this is $100. Mine died shortly after buying it. It's cheap. It's inconsistent. I should have returned it. But that's an even bigger pain.
  • Works well By christopher on 8/13/2016

    Never had a problem and have been using mine. Used a ring to make sure the pellets didn't drop into the overflow, but overall has been consistent and reliable.
  • Piece of junk By Wolffmanmn on 8/5/2016

    The lid is temperamental. Had several spills of food. Filled the tank with food several times. Lid should have some more secure mechanism to attach and remove. Also finicky trying to detach until from base that attaches unit to tank. Lid popped off doing this as well.
  • Great for vacations By RJ on 7/25/2016

    I'm not sure why people are being so picky with this feeder...? Sure it makes some noise (only while its rotating, so once or twice a day for 30 seconds).
    The noise dosnt bother me.
    The amount of food it dispenses is hit n miss since its impossible for it to feed an exact amount. The type and size of food would regulate this.
    As for opening it up to refill, its easy to attach it to the tank and take it off, so why not just take the unit off before refilling it?

    My main concern about this would be that its not water proof at all. This sits right on top of your tank and the USB ports are too close to water for my comfort. Any splash near the unit and you could get potential issues. This is my first feeder so I'm not sure if other feeders are waterproof or not. I feel the unit and USB should be waterproof.
    Other concern is the price. I love that it connects to my Apex, but I think the price is too high for what it is.

    4/5 stars due to not being waterproof and price.
  • Great but not perfect By snow_max on 4/23/2016

    The feeder is super slick and I love the fact that its programable with the Apex. You have may more options over all the other feeders on the market. That being said be cautions when removing the lid while its hanging over the tank. I dumped a whole cylinder of food into my reef because I wanted to change the feed rate. I don't understand why all the other reviewers complain about the sound. It does make noise, how ever I wouldn't call it annoying...unless you're feeding in the middle of the night and the tank is in your bedroom. Otherwise this is a great product and worth trying.
  • Worked great By Robsyp on 4/9/2016

    Worked great out of the box. Had no problems.
  • Less then expected By Mike on 4/3/2016

    I have not changed the code on my Apex for months but once in a while the feeder does not feed. That is unexplainable by everyone I have talked to. Other then that the feeder has kept my fish alive for over a year now. It is noisy but my concern it for it to feed the fish. It drops about the same amount of food each time with 1mm pellets. Not perfect but close enough to keep the tank happy. BUT when it comes time to refill, you have to be careful. It is almost impossible to remove the canister. Most of the time all that comes off is the canister lid and ALL the food dumps into the tank. Advice: remove the entire feeder tilt up and remove the lid. It only takes a little extra time and no disasters.
  • good add on, needs some design improovements to get 5 stars By m on 2/21/2016

    it's a bit noisier than it needs to be.
    sounds like the gear quality and gear mesh is not quite right.
    the food compartment should have a twist lock lid so the entire compartment can be removed without accidentally opening it.
    on a positive note, it is fairly easy to program.
    i have mine set to supply basic daily feedings of pellets and add other things (frozen foods and treats) by hand.
  • The best Feeder By Xavier on 2/18/2016

    A must have if you have the Neptune Apex ....! Control the times per day that you are able to feed you tank !
  • Nothing but issues with this device By Jeff on 2/4/2016

    I control my tank with the Apex controller and absolutely love it. I have never had any issues UNTIL I purchased this device.

    First, the ability to 'daisy chain' multiple feeders together went out and I had to buy new cables to hook them directly into my Energy Bar/Aquabus.

    Then one of them got 'stuck' while rotating and would not return to the closed position (into the trash it went).

    Then, out of the blue, they took my Energy Bars down - knocked communication with the controller out on one and stopped ALL outlets on another. I know it was this device because after unplugging my Energy Bar for a reboot/re-connect with the controller, as soon as I plugged one of the AFS devices in, it took them down again...

    I'm not sure why Neptune continues to sell these items...

    Back to the Eheim everyday feeder for me...
