Is my tap water ok for waterfarm?

Just got my EC meter today and tested out my tap water to get a reading of 200PPM.

Will this be ok or should I buy some bottled water? I've been looking around for RO water and can't seem to find anywhere that sells it where i'm from.

Kinda high, mine is 50 to 55 RO water is pretty much any non spring bottled water.

trying eavng you water for 24 hours before using it helps loads :)
Forgot to add. I had a 2ltr of tapwater that has been sittin there for more than a few weeks used for house plants. Took a reading from that and it was 190PPM. Hmmm....

Leaving water sit out only helps evaporate Chlorine. It does nothing to alter ppm's or "hardness". You need Reverse Osmosis or DI filtration or distillation to remove hardness. Click on the link in my sig if you want to learn more about water.:blsmoke:

I grow hydro and I use tap water all the time . I do adjust the PH . I don't worry about leaving the water out for a day or two . If the water was that bad , I would have a whole house full of dead house plants . If your house plants can take it .... so can your special crop.

Just because one grower is able to use their tapwater doesn't necessarily mean another grower can do the same with the same results. I can't use tapwater for my houseplants even! If your tapwater is too hard (and hardness can vary wildly depending on your geographical location, or the time of the year) it can have an antagonistic effect on certain nutrients which manifests as a deficiency. Not all are so lucky to have good tapwater.bongsmilie

you should be fine...I know in hydroponics its great. You should only have to install a RO system if you're on well water and/or your water source smells like sulfur
