Holiday time often spells trouble for aquarium owners: Who will feed? Who will clean the filter? The nice person who will feed the fish is usually the only real problem. Since fish usually appear to be hungry, that person will permanently succumb to that impression and overfeed the fish beyond hope. Only when the holidaymaker returns and the 1-litre container of fish food is empty even though he only has 6 neon fish, does the problem become evident.
Automatic feeders or food portions in individual envelopes with one per day can remedy the problem. The JBL Click dosage dispenser is a truly perfect option that permits the aquarist to give the substitute feeder one clear instruction: 5 fish = 1 x click/10 fish = 2x click. This will prevent overfeeding with all of the unpleasant consequences! The JBL Holiday food is a nice option for a short holiday: The food is contained in a mineral cube (gypsum = calcium sulphate). The fish "work" for their food, as the cube only dissolves when the fish feed, without clouding the aquarium water. The amount of food is enough for a normal communal aquarium or gold fish basin. And if you're only going away over the weekend, you can buy JBL Weekend.
It may interest to know that filters do not need to be cleaned during a holiday! Sufficiently large internal filters like the JBL CristalProfi i 100 can go without cleaning for 5 weeks with no trouble. So, put out the Click dispenser with feeding instructions and enjoy your holiday! It's that simple.
