Hugo Weekend Blocks keep your fish fed and happy for 3 – 4 days.
The calcium carbonate block dissolves slowly over a few days, releasing food particles in to the water.
As a guide, one block placed in a 45 litre aquarium should be sufficient to supplement the diet of 10 – 15 average aquarium fish for approximately 3 – 4 days.
Hugo Weekend Blocks are not suitable for marine aquariums and are recommended for tank temperatures between 20-25 degrees.
