Healthy food for all aquarium fish while you\'re away on holiday. Tetra Holiday Menu provides your fish with a varied and reliable food supply while you are on holiday and lasts for up to 14 days, depending on the size of your aquarium and the number of fish. Thanks to Tetra’s gel food technology, this holiday food is produced on a gel basis rather than as a gypsum block. The main advantage of this is that the food does not negatively affect the water quality in the long term and therefore the water values remain stable. The gel food block with Tetra’s BioActive formula is 100% edible and contains protein-rich pellets as well as delicious daphnia and krill. It also contains all the essential vitamins, trace elements and minerals that fish need to stay healthy. The aquarium fish can nibble at the block as needed, because it does not dissolve by itself. - Varied holiday fish food for up to 14 days - 100% edible gel food block - Contains protein-rich pellets with BioActive formula - Contains all essential vitamins, trace elements and minerals - Enriched with extra-tasty daphnia and krill - For optimum water values without turning the water cloudy Includes: 1 x Gel Pots Recommendations: 7 Days or less feed half a pot to 5-15 fish in a 60l tank 7 Days or less feed half one pot to 10-30 fish in a 60-120l tank 7 Days or less feed half 1-2 pots to 20-50 fish in a 120-200l tank 14 Days or less feed half a pot to 5-15 fish in a 60l tank 14 Days or less feed half two pots to 10-30 fish in a 60-120l tank 14 Days or less feed half three pots to 20-50 fish in a 120-200l tank Holiday Checklist: - Test the water and do a partial water change of 30% - Check your filter but do not clean or change the filter sponges directly before leaving for holiday - Ensure oxygen supply by aeration or filtration outlet - No additional feeding!
