    Before you spend any money on water purification equipment (it may end up being an unnecessary expense), contact your water supply company and ask for the water quality report.
    This is usually published annually or quarterly and it is most likely on their website as well.
    This report will list all the water parameters, including treatment chemicals that were added that would reach the customer's home.

    From there you can review the list of compounds and chemicals and research if those will cause any problems for the plants with the concentrations listed on the report.

    You can't fix it if it aint broke.

    I went online to - to check what my content of salts was and it is 275 ppm which is high / hard. I now use -on my besseae hybrids and other delicate orchid species like my Lycaste skinneri etc, purified water with 20% tipped out of the bottle and topped up with 20% tap water to get the salts back in proportion. So far no worrries. I use tap water for my phals, some phrags and just about everything else. My Vanda coerulea gets tap as do my paphs and they are growing and blooming and seem to be OK on it.

    As we have extremely good tap water in Sweden I have always wonder why people suggests that freezing or boiling should purify water! (No one that promote this treatment in Sweden talk about removing precipitates).
    But in this thread I finaly found the answer I have looking for, many thanks!

    I have a distiller. I drink distilled water and use only distilled water for my orchids. I spray and conventionally water them with distilled H2O. They love it.

    My approach is that whatever the medium one has their plants in, the nutrients will be derived from the gradual decomposition and degradation of the organic and inorganic components in the mix...just as it would be in the natural setting. Wood, bark, charcoal, coco husk can be the source for whatever N,P,K the plant needs, while inorganics like perlite or vermiculite can provide the trace elements/minerals/ions the plants might otherwise need to grow successfully. I have no need for added salts/fertilizers, because the plants take up what they need at the same rate they would in the wild. It's the same phenomenon they would experience with rain water and other natural sources of humidity in nature.

    I feel that the plants really respond to this.

    So basically what I'm saying is that one shouldn't consider distilled to be "dead" water. The combo of the distilled and whatever medium you are in provides all the nutrients an orchid might need, since they grow quite slowly, and being epiphytic, are highly adapted to taking their own nutrients out of the wood and whatever components surround them. Also remember that you will never eliminate 100% of all the ions that would be in the water. There will always be some residual calcium and or other mineral components left on the surfaces of your containers from normal handling and use which will go back into solution and be dispersed again.

    Also, if you use distilled, you don't have to worry about the possibility that your orchids (or other plants) can't handle certain hard water or certain amounts of trace elements. Distilled H2O is universal...good for all plants if you plan the use of it correctly.

    After researching online, I discovered that my municipal water is too alkaline, 8.0 - 8.5. I purchased "pH down" about 2 yrs. ago. It's a solution that's mixed with the tap water and only requires a few drops to a quart. If effectively drops the pH. I like to maintain the pH, after draining thru the bark between 5.8 - 6.5. Since using slightly acidic water my orchids are much healthier....the pests and diseases have decreased significantly along with increased growth and blooms. I'm so glad I made this change!
