sera guide - Shrimps and crayfish

21 Now, finally, the aquarium is decorated and planted; filter, heating and lighting work as they should. The sera tests reveal good water quality. Feed only sparingly during this start-up phase (see page 24 ff., please). • Pour sera filter biostart onto sera sipo- rax mini. Put the filter into operation. The biological breakdown within the fil- ter starts right away. • Add sera bio nitrivec to the aquarium water. This will start the biological pollu- tant breakdown in the aquarium. • Add 10% of the animals on the next day (1st day). Add sera bio nitrivec (normal dose) each day for 10 days running. You will shorten the time in which the filter bac- teria become active by doing so. • 4th day: Add 30% of the animals. • 5th and 7th day: check ammonium and nitrite. sera toxivec quickly neutralizes too high values. • 8th day: Add another 30% of the desired animals. • 10th day: same as 5th and 7th day. • 11th day: Add the final 30% of the desired animals. Introducing the animals 21 The surface of one liter (one US quart) sera siporax mini has almost as much biological break- down power as 34 liters (9 US gal.) of ceramic filter material
