A 175 ml drum for fish that eat properly.
A hundred and 75 millilitres is several times what a standard feeder holds, which is what a tank of goldfish or a pond of koi actually gets through.

Why you'll love it
A goldfish eats several times what a tetra does. A 175 ml drum is the difference between a feeder that covers a fortnight and one you refill on day four.
The clamp handles a normal tank rim; the velcro strap handles everything else: a pond post, a hood with no lip, an odd shaped edge. Most feeders give you one option and fail on unusual tanks.
The wide outlet suits sinking and floating pellet, which is what larger fish are usually fed. Fine flake is better handled by a smaller feeder with a narrower gate.
Good fit if
Look elsewhere if
Standard feeders are sized for community tanks, where a small daily portion means a hopper lasts weeks. Goldfish and koi eat considerably more, and a small feeder emptied in four days is no use for a fortnight away regardless of how well it works.
Working out how long a fill lasts is straightforward and worth doing: load it, run it for a week at your normal setting, and see how far the level drops. That figure tells you what you can actually rely on, which the stated capacity on its own does not.
Aquarium feeders assume a glass rim to clamp to. Pond edges, coping stones and open topped containers offer nothing of the sort, which is why the velcro strap matters: it fastens around a post, a rail or a bracket where a clamp has nothing to grip.
For outdoor use, position matters more than in a tank. It needs to be sheltered from rain, since water reaching the drum will set the food solid, and out of direct sun, which cooks the food and shortens the life of the plastic. Under an overhang or inside a small housing is the usual answer.
Pellet and granule are what this is built for, and they suit it well because they flow freely and tolerate damp far better than flake. The adjustable outlet sets the dose, so match it to what the fish clear in about two minutes and resist the temptation to be generous.
Two AA cells rather than a mains adapter is a practical advantage outdoors, since there is no cable to run to a pond and no plug standard to worry about. Carry spares and change them before any long absence rather than at the first sign of a slow drum.
Up to four feeds a day is more useful with large fish than it sounds. Goldfish and koi digest better on several modest meals than one heavy one, and spreading the same daily amount across three feeds puts noticeably less strain on the filter than dropping it all in at once.

The details
Empty the drum completely at the end of the season and dry it out. Pellet left in a damp feeder over winter turns into a solid plug and often ruins the mechanism, which is the most common way one of these fails outdoors.
Take the batteries out for storage, since a leaking cell over a winter destroys the contacts. Check the seal and the outlet before putting it back into service in spring, and run it for a few days on a test schedule before trusting it with an absence.
Loved by real pet parents
There is no lip at all on the edge I wanted to mount to, so the fixed clamp was never going to work. The strap went round a post instead and it has held since May. Most feeders give you one mounting option and that is that.
They eat a startling amount compared to the little tetras in the other tank. At two feeds a day the drum went a full two weeks without needing a top up. The wide outlet handles sinking pellet without jamming.
It is exactly as described for pellets, the outlet is wide and nothing bridges over. I tried fine flake in it out of curiosity and it dumped far too much, so that is clearly not what it is for. Sticking to pellet it has been faultless.
Splitting the daily amount across four drops rather than one has stopped the scramble at the surface. The adjustable outlet lets me make each one smaller to match. Two AA cells have run it since December.
Worth having two AA in the drawer before you start, because none come with it. Beyond that the drum is a good size and the clamp went onto my rim without any packing. Portion setting is a simple slide and it has held its position.
My old feeder held a fraction of this and I was topping it up every few days. 175 ml means I fill it and forget about it for most of a fortnight. Same routine, far less fussing.
The drum and the outlet are good and it has not missed a feed since I set it up. The velcro strap does the job but it looks rough on the side of a pond and I can see it perishing outdoors. I would rather it came with a proper bracket for that.
It mounts firmly enough but the screw has worked slightly loose twice since I fitted it in September, both times after I had moved the lid. Half a turn and it is solid again. The feeding side has been completely reliable.
Left it running over two weeks in July with the outlet wound most of the way shut. Came home to fish that were clearly fine and water that had not gone green from leftovers. Two AA and a full 175 ml drum was all it needed.
Good questions
It is not weather sealed, so it needs to sit under a cover or inside a pond house. Rain into the drum turns the pellet to paste and jams it.
The manufacturer makes one and we have chosen not to stock it. It is an unbranded radio device with an unvetted app, and we would rather sell the version that just works offline.
For a few goldfish on two feeds a day, comfortably a couple of weeks. Fill it and count the days once at home so you know your own number before a trip.
Yes, with the velcro strap for edges that have no lip. Shelter it from rain and direct sun, since water in the drum sets the food solid and heat degrades both food and plastic.
Not this one. It runs on its own timer with two AA cells, which is the compromise for working outdoors with no mains or network to depend on.
It depends entirely on your fish. Load it, run a week at your normal setting, and measure the drop. That figure is what you can rely on.
