Bubbling tap water is a waste in my opinion. I have heard from many reputable sources that bubbling tap water for even 5 days does not in fact remove chlorine nor chloramine.
I do like to pump air into my res using and air pump and air stones before watering as I feel the oxygenated water is appreciated by the plants.
I use R/O water myself and love it. I have a friend who does just fine though with striaght tap water. Many Organic gurus will tell you its not truely organic unless you are using R/O water though.
Where might you get this ?"potassium bi-carbonate"
Seriously? I can dispel that myth, and further clarify it for you. First, for chlorine (Cl) to offgas, you don't even need to bubble it, you only need to leave the body of water exposed to open air for about 24hrs. You can get a test kit and test this out for yourself, but I can also assure you that if it weren't true, fishkeepers wouldn't have been using this method for decades upon decades. Assuming you have some acuity left in your sense of smell (mine's compromised) then you can also simply use the smell test. If you smell Cl, it's still there.Bubbling tap water is a waste in my opinion.

Another myth is that the air bubbles that are passing through the water column are, in fact, what is aerating the water (which really means helping or even forcing the O2/CO2 exchange to occur). First, it is only at the water's surface that this exchange normally happens (outside of a venturi). Second, even if using wood blocks as the 'stone', the kind that create superfine bubbles, usually the surface area is completely insufficient as to allow much of a gas exchange. What is really happening is that the bubbles are creating surface turbulence, and it is by this action that the gas exchange occurs on scale.I do like to pump air into my res using and air pump and air stones before watering as I feel the oxygenated water is appreciated by the plants.

Nice..but if you don't mind me asking what do you use to ph your water past week 4 of flowering?
Could I use pro-tekt throughout the whole life cycle? even if it's only to ph?
Ironlung...i'm not using RO I just switched to my regular 'ol tap water. It's ph is 6.7. I leave the water out for atleast 36 hours....when you say bubble what do you mean?
Great post Seamaiden. Dodged over the NHCl, (didn't sink in) first time around. My water- a mix of sources in a seaside, agricultural area- needs to be heavily sedated and NHCl is a big part of the cocktail. I obviously RO my water but was wondering if sodium thiosulfate might a good idea in addition?Chloramine is a different beast, it's NHCl (chlorine bonded with ammonia) and that bond needs to be chemically broken. Most commonly used product in places like fish shops and public aquariums is dry sodium thiosulfate, which breaks the bond, dechlorinates and leaves the ammonia as a residue. Again, you can pick up test kits to determine for yourself how and that this does indeed work.
So, in short, aeration or just leaving in an open container allows Cl to outgas, but does nothing for NHCl.

If they've appointed themselves guru, perhaps they should be questioned. I think everyone should be questioned, though.
Donny- thx for share. Exactly what I did before I got more patience going and what I still do when I'm "in a hurry."Chemical reactions aren't necessarily quick, and anything worth doing is worth taking time on. Also, take lots of notes and don't answer the freakin phone in the midst of chemistry projects! Glad I didn't have to kill my seedlings to figure that one out...
I would think that going through the RO membrane and carbon filters would have pulled that NHCl out of the water column, Ganja. You may want to test it, but aren't you culturing microbes successfully using that water? If so, they're as good as a canary in a coalmine, IMO. Just like using sharks, skates, rays, sponges and sea squirts as a gauge of water quality.
Wouldn't a few drop of lemon juice or roots trinity be a better choice ? Never have used vinegar before always the above mentioned
Thank you Ganja, that is the same exact reason why I am using distilled vinegar, and thank you as well, original poster for allowing me to also gain some knowledge from your thread. :)When I was really broke, (rather than just broke) I used white, distilled vinegar and quite honestly, I didn't see any detrimental effects. That doesn't mean that I wouldn't have had a better response had I been able to afford cold pressed apple cider vinegar. I have lemon trees and used lemons until I ran out. Nowadays, I use food grade citric acid which is what lemons give you. Depending upon how rough your water supply is and the size of your grow, you can go through lemons pretty fast.
True Seamaiden. Common sense should have been enough to answer my question but know very little about chloramines and have never used sodium thiosulfate so was just covering the bases. My ROd water supply has sort of a sulfur-methane- aged shit smell- sometimes it smells like vomit. My canary died last week. Does that mean that I should run?I would think that going through the RO membrane and carbon filters would have pulled that NHCl out of the water column, Ganja.
