Graeme,
Autofeeders range from about £10-£15 upwards (always upwards
).
I think Hagen do a couple of feeders which should be suitable for that tank - let me go and have a look.....
There seem to be two:
Nutramatic 2X Fish Food Feeder - basically a reservoir of food which is dispensed every twelve hours by a single rotation of the drum. I have one of these which is very poor with flake food as it tends to trap evaporation and clump it all together. Online prices in the region of £12.
Nutramatic Automatic Fish Feeder - I don't have any experience with this one but it look a lot better. Sales blurb states "Dispenser opening is oriented upward to reduce moisture intake". Online prices in the region of £29
Other makes:
Fish Mate F14 Aquarium Feeder - serves 14 individual meals up to four times a day. I have just got one of these and it looks good as you can vary the timing and content of individual meals. It also has the option to accept an airline intake to help prevent moisture problems. I haven't needed to try it out yet so I can;t say how good it is. Online prices in the region of £20
Eheim 3581 Automatic Feeder - "Electronically controlled programming, with up to 4 daily feeding times. LCD display with clock." I haven't used this one myself but the sales blurb looks good. Online price in the region of £27
Hoppy Toppy Automatic Fish Feeder - twice daily feeding, adjustable feed quantity, airline attachment to help keep food dry. Another I have no experience of. Online price in the region of £27
Hobby Rondo Steward Automatic Fish Feeder - "Automatic mains transformer powered fish feeder with heated feeding drum, Digital LED Display panel, Adjustable slide for feed quantity, Fully programmable, Heating element for food drum, Feed times can be set for every 3, 4, 6, 8, 12, 24 and 48 hours". Sounds a bit like the Rolls Royce of feeders - and the price reflects it. Online prices in the region of £48
HTH, Eddie
