Your biOrb
The aquarium life cycle
The cycle starts as soon as you add
Biological
Booster
to your aquarium. The beneficial
bacteria in
Biological Booster
will start
to colonise the
biOrb Ceramic Media
(Supplied). These beneficial bacteria
form a vital part of the biological
filtration by breaking down poisonous
waste created by the fish.
Stage
the waste produced by
your fish and uneaten food will start to
rot producing Ammonia. This is extremely
toxic to fish but will be gradually broken down by
beneficial bacteria in the Ceramic Media, so it’s important
that only one fish is added to the aquarium at a time and never add any more than the
recommended number of food pellets. Following this rise in Ammonia the Nitrite level
will also start increasing
until the Nitrospira bacteria have time to reproduce in
sufficient quantities to remove the Nitrite. The final stage of the cycle
will see a
Nitrate spike; this is the least harmful to the fish and will reduce to very low levels over
time. Weekly use of the
biOrb Water Optimiser
and changing the filter cartridge
every 6 weeks will keep Nitrate to a safe level.
Adding and feeding fish
After 24 hours you can add the first fish to your aquarium. The chart will help you. Fish
transferred from an existing aquarium must be introduced in the same way as new
fish. For every 1”/2.5cm fish added it will take at
least 28 days for the aquarium to cycle and the
filtration to catch up. Add at a rate of one small
fish every 28 days until maximum stock level is
reached.
too many fish too soon will create
high ammonia levels poisoning the fish
(see
Aquarium Life Cycle above).
It is recommended that you start with a hardy
species, consult you local aquarium store for
suggestions. Non-hardy fish such as Neon-
Tetra or Blackmoors are not recommended for
the first month.
Take care not to overfeed your fish and remove any leftovers after 2 mins. Different fish
have different nutritional requirements so use an appropriate food.
Small goldfish
2-3 pellets, ideally every other day
Small tropical fish
4 micro pellets, ideally every other day
When opening the lid to feed the fish, water droplets may have formed inside
the lid. Wipe these away to prevent water running down the back of the aquarium.
