water is reverse osmosis/de ionised, the units usually work on water pressure, I've used one for about six years. They remove 99% of contaminants out of the water and change it on a molecular level. This water is not safe for fish alone and it needs to be tuned to the right parameters. I usually re-mineralise with de-chlorinated tap water. Special salts are available for fresh and salt systems. The filters need changing every 6months, the membrane lasts around 4years, the DI
resin needs changing, this depends on amount of water produced and condition of water in the first place, for me it's about every 6 weeks. You will need a TDS
(total dissolved solids) meter to monitor DI
resin change. This can be used as a rough guide in all tanks too!
To properly test your tap water you will need a Gh
(breakdown of TDS
) and a pH test kit(s).
Copied from somebody I helped before, thought it would help here too.
