Incoming mains or borehole water is pre-filtered with sediment and carbon cartridges before being forced through the reverse osmosis (RO) membranes to produce water suitable for use as the base for marine and tropical fish environments.

This purifying technique reduces issues with algae growth, that affect coral and the tank, by removing the elements of phosphate, silicate and nitrates. This level of pure water is too pure for the fish and has a low pH, so appropriate buffers of beneficial mineral salts are added to make the water suitable for every type of fish.

Some fish keepers prefer to make de-ionised (DI) water, stripping out all of the salts and ions, this process typically follows the RO stage (to save costs of the single-use DI resin) to polish the remaining small percentage of salts and ions remaining after reverse osmosis.

Stages of Filtration & Water Treatment

RO Water Production

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

RO Water Production - Fileder Filter Systems

SPECTRUM Aqua RO50 System

Typically used

AQUARO50

OR

Sediment Removal

Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.

SPECTRUM TruDepth Standard Spun-Bonded Cartridge

Typically used

SSP-5-97/8

Pentair 10″ Plastic Housings

Typically used

No103GSTBK/BL3/4"

Chlorine Treatment

Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.

Salts, Ions & Other Contaminant Removal

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

Total Salt & Ion Removal

The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.
