Got a reverse osmosis system getting put in a in a few days. It will be one for the whole house so my plants will benefit also. Meanwhile, I need to find affective ways to remove chlorine from the tap water. I know that leaving the water sitting for a day or so will allow some chlorine to dissipate but what other ways are there to make it happen safely for plants?

Thanks for coming through again Speed! I have an RO system that I have been looking at for under sink installation for the house. I'll do the price comparisons. I had a water softener also but it broke one time too many...

Chlorine(CL) reacts with air to create chlorine gas(CL2)

An air stone in the bottom of a bucket of tap water may help remove chlorine much faster than just letting water sit out. But I haven't tested this, just sounds right in theory.

Chlorine will be removed by the RO system.

I don't grow but I have a R.O. in my basement with a 10 gal drum, it only takes up about 3 cubic feet but its water with 2-3 ppm consistently, i love them.

this isn't really a helpful post, i just wanted to express my love of R.O.

Thanks for the input everyone. I got a bucket of of water sitting. I'll throw an airstone in it right now. Hopefully, I will have an RO by weeks end.

I use the drops for aquarium use. 1 drop/gallon removes both chlorine and chloramines and tropical fish are way more sensitive than any mj plant.

BTW, chloramines will not evaporate out of water like chlorine. Depends if your water system uses it or not.

RO by itself will not remove chlorine or chloramines. It requires a special, extra filter that is usually purchased separately.

I'm no expert but I'm pretty sure anything over a few PPMs chlorine in the water is above the limit...



http://www.seattle.g...t/01_013138.pdf (page 2 has a chart)

Chlorine (ppm) MRDLG = 4 MRDL= 4 Average = 0.84 Range = 0 to 2.2 Water additive used to control microbes

MRDLG: Maximum Residual Disinfectant Level Goal - The level
of a drinking water disinfectant below which there is no known or
expected risk to health. MRDLGs do not reflect the benefits of the use
of disinfectants to control microbial contaminants.


Translation: EPA says below 4ppm there is no risk to human health. Seattle has an average of 0.84 PPM chlorine.


This basically says the EPA limits chlorine levels to 4 PPM.... which is why I've always found the whole "leave your water out for a day" argument to be forum garbage...

In theory I guess this might be important to organic growers, but I doubt a few stray chlorine molecules will do much damage on a thriving organic ecosystem.

Which brand do you use? and how long have you tested it with your plants?

i was always told water sitting out can get stagnate and get bacteria? i dunno how true or what the pros and cons are but its worth looking into i think. just dont want u giving your babies bad water thinking its doing good for them..

Yeah, I know what you mean. The water doesnt sit in the bucket for very long though and when it is, I have an aerator going. Once its good, I bottle it. So far its been pretty good. I transplanted my girls last week and the roots were nice and white.

What I have now is AZOO, ut they are all pretty much the same.

Been using the Azoo about 3 years, but others, like AmQuell for much longer.
