Checking and adjusting the Sg
When mixed with the correct
volume of water at 24˚C/75F the
specific gravity (or Sg) of the salt
solution should be 1.024. To test
this, take a small sample of newly
mixed salt water in a beaker big
enough to float the hydrometer
(supplied), an Sg reading can then
be taken as shown in the
diagrams (right). The water line
should be level with the green
area on the hydrometer.
If the Sg is above 1.024, slowly
●
add more lukewarm water.
●
If the Sg is below 1.024, slowly
add a strong salt solution.
NEVER add salt directly to the
aquarium. Allow time for the salt
to fully mix and keep checking
until the correct Sg level of 1.024
is reached and the water line is
level with the green area on the
hydrometer. Stir thoroughly and
let stand before use.

Frequently asked Questions...
I've added too much freshwater, what can I do?
If, when mixing salt water for your 25% water change you
accidentally add too much freshwater, the salt concentration will be
too low. If you have a biOrb CLASSIC 30, LIFE S30/P45 or biUbe you
will have spare Reef Salt. Following the Checking and Adjusting Sg
section above you can use this spare salt to correct low Sg levels. If
you have a biOrb CLASSIC 60 or LIFE 60 you will need to purchase
additional salt, please contact our customer helpdesk:
marine@reef-one.com.
What are the white crystals on the top of the aquarium?
These are white salt crystals called Creep, they will form around the
top and lid of your aquarium and should be regularly wiped away
with a damp cloth. NEVER add these salt crystals back into the
aquarium as the sudden rise in salt levels (Sg) will harm your fish.
Can I use RO water?
Aquarium stores will often recommend the use of RO water (or
'Reverse Osmosis' water). Specialist water purifying machines are
used to produce RO water, which is simply purified tap water with
approximately 98% of dissolved solids and organics removed. RO
water is normally required for keeping Corals but can be used in a
standard fish only aquarium if your tap water has excessive levels of
harmful chemicals. In most circumstances mixing your own salt
water using the supplied Reef Salt is more than sufficient as the
Marine Filter Cartridge (supplied) is specifically designed to work
with tap water.

Can I use a standard Filter Cartridge?

No, a standard Filter Cartridge is not suitable for use in a marine
1.040
aquarium as it does not contain the right mix of water conditioning
chemicals that the specially developed Marine Filter Cartridge has.
