STEP BY STEP GUIDE TO SETTING UP A COLDWATER
Choose a suitable location for the aquarium. It should be out of the
line of direct sunlight which would magnify the temperature in the tank
Check support is sufficient to hold the large weight of water in the
aquarium (1 gallon weighs approximately 10 lb).
Polystyrene tiles should be placed under the aquarium.
Purchase the remaining equipment in the checklist.
Place the undergravel filtration tray in the aquarium (if this system
is to be used). Cover the tray to a depth of 4 cm with washed coral sand,
shell sand, or beach shingle. Rocks should be collected and placed in the
A 'Gravel Tidy' with two substrates is eschewed in this type of aquaria,
because the crabs will dig it up.
Add real seawater from an unpolluted source, or mix up the artificial
salts according to the instructions on the packet. The specific gravity
at 15ºC should be 1.025.
Place the Powerheads or Capsule Filtration System in place and connect
to the electricity supply.
Electrical sockets are best located above the aquarium in case of the
rare event of the tank leaking.
If artificial sea water is used place a piece of mussel
(alternatively, 'nitrifying' bacteria cultures can be purchased) in the
A population of filter bed bacteria needs to be established to introduce
the 'Nitrogen Cycle' into the confines of the aquarium.
This cycle renders the waste products of the fish, invertebrates and
Wait a week before introducing hardy animals like Beadlet
Anemones and Shore Crabs. Stocking should
be gradual to full levels after one month.
Connect 'cooler' and thermostat and test that
it is working order. The cooler should be put into operational use the
day before the fish and other life is introduced. The filter bed bacteria
multiply quicker in warmer temperatures.
NB. The first life of interest to the aquarist
appears on the shore for most of the length of the British coast in February
and March. The cooler may not be necessary until June.
