CO2 ACCESSORIES
A TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution.
CO2 is used within planted aquariums to provide food for photosynthesis resulting
in healthy plants and a healthy aquarium.
Since dissolved ionized solids like salts and minerals contribute to the conductivity of a
solution, a TDS meter measures the conductivity of the solution which is then converted
to a TDS reading.
TDS is directly related to quality of water i.e. the lower a TDS figure, the purer the water. As
an example, reverse osmosis purified water will have a TDS between 0 and 10, whereas tap
water will vary between 100 and 400.
It is especially recommended if you are using D.I. resin that you should also have a TDS
meter to allow you to determine when the resin has become exhausted.
