    I don’t have a RO water system yet but I’m running a small water distillation unit that delivers ± 5 liter / hour. I use piped on site demineralised water to feed the system, it keep the system clean from lime and other build-up inside the boiler. Is this water suitable for marine aquarium use? I suppose one have to add all the minerals taken out during the demin and distillation prosess. The other option is just plain distilled water. Your advice please.

    I checked the conductivity.

    Demin supply on tap: 0.9 µS/cm @ 22.5°C
    Distilled Demin: 0.4 µS/cm @ 22.5°C

    might cause a ca and ph dip if used as topup. i would use the distilled to add various supps to minimise swings

    Make sure your condenser isn't made of copper or a metal

    Enen if it is made of copper, it does not give off any copper. My uncle use it in his lab to test chemicals, so that mean that it is the best way to get the water as pure as possible.

    Hi Danie

    I would use it. But if you are not sure, we sell RO water for R0-70/liter and Gezina is not to far from Mountain view.
