The Truth About Chloramine and Chlorine

Hello friends,

I live in an area where chloramine is used to disinfect the local water supply, but I'm concerned that this is greatly reducing the potential of my plants.

My general question is: how does chloramine affect the efficacy of certain plant fertilizers and teas?

My more specific question is: do chloramines make the use of plant enzyme products such as hygrozyme ineffective? Do chloramines make the use of beneficial bacteria products such as Advanced Nutrients Tarantula and Piranha useless? Does chloramine make the use of carbohydrate teas such as black strap molasses, Botanicare Sweet, and others useless?

Here is what I understand (or think I understand) about chlorine and chloramine and why I think using the above products might be less effective when using tap water that contains either chlorine or chloramine.

I understand that chlorine is used in local water sources to kill off many harmful bacteria in water and that this ultimately helps us humans drink cleaner, more disease free water, killing up to 99% of water pathogens. I know that recently municipalities are changing to use of chloramine because unlike chlorine, chloramine retains its chemical composition in the water long after the water has been pumped out from the local water source due to the addition of ammonia to the chlorine molecule. With water sources that use chlorine only, a farmer can simply let the water sit for 24 hours as the chlorine dissipates into the air and is then ready for use with plants. With chloramine this isn't so, as the ammonia makes the chlorine in the water much more stable.

This would lead me to think that the use of beneficial bacteria products such as Tarantula and Piranha are wastes of money, since the instant they are used in water containing chloramine, they are killed. And since sugar based products like molasses are used in plant food to 'feed' these beneficial bacteria and thus translates to faster growth and healthier plants, without any living beneficial bacteria culture in the food the sweeteners are rendered useless placebos.

I repeat, what's the scoop on tap water with chloramine in it? Does it make the use of the products mentioned above pointless and a waste of money? Do I need to get a reverse osmosis kit? Do reverse osmosis kits even filter chloramine or do they only work for chlorine? Maybe I need a de-chlorinator that also works for chloramine? Please help, I don't know if I've been wasting money on all these products and I'm reluctant to just go out and buy a dechlorinator just to be on the safe side. I don't want to just throw more money into this.

Thank you, and I apologize for the long post, I just wanted to avoid having to explain myself a dozen times before getting to the nitty gritty, if you know what I mean.

I don't know anything about cloramine so I won't speak to that but what I do to remove the chlorine from the tap water that I do water with is to fill buckets of tap water and let them set for a day or two in the sun. Then I nute up and feed my plants. No chlorine.
works for me and it doesn't cost anything to let it burn off naturally. You have to plan ahead a little but I usually don't get all wired up if I forget either. I'll just go ahead and run fress tap but I do try to have a couple buckets full of water at all times and I almost always do. Not a big problem.
If chloramine burns off like chlorine, you're golden.

Some wiki info for ya! :-)

Removing chloramine from water
Chloramine can be removed from tap water by treatment with superchlorination (10 ppm or more of free chlorine, such as from a dose of sodium hypochlorite bleach or pool sanitizer) while maintaining a pH of about 7 (such as from a dose of hydrochloric acid). Hypochlorous acid from the free chlorine strips the ammonia from the chloramine, and the ammonia outgasses from the surface of the bulk water. This process takes about 24 hours for normal tap water concentrations of a few ppm of chloramine. Residual free chlorine can then be removed by exposure to bright sunlight for about 4 hours.

Home brewers use reducing agents such as sodium metabisulfite or potassium metabisulfite to remove chloramine from brewing liquor as it, like chlorine, it can be removed by boiling, however boil time to reduce chloramine to a terminal measurement is longer.[12] Residual sodium can cause off flavors in beer (See Brewing, Michael Lewis) so potassium metabisulfite is preferred.
Chloramine can be removed from bathwater and birthing tubs by adding 1000 mg of vitamin C (as the ascorbic acid form) to a medium size bathtub (about 40 gallons of water).[

The ascorbic ascid methods sounds pretty easy. You'd have to adjust the pH again after though before adding you organic watchamicallit. ;-)

im really curious to know as i just found out that my city uses chloramine as well. I have been using great white, bud candy and liquid karma and they seemed to work great last winter. all of a sudden the ph of my tap water drastically changed, and when i found out that they recently added chloramine to the water. i started to wonder if thats why my recent crop was drastically smaller? anyway. im buying an RO soon, so i dont have to fuck with it anymore. better safe then sorry.

They like a slightly acidic soil anyway. 6.5 is just about perfect for most strains. Soil buildup would be a problem, though.

Why not just buy aquarium drops? They are really cheap and will free up the chloramine.
That's exactly what I thought too Gastanker!

Yeah I just did a search on my city's website and confirmed that they use chloramine.. Damn should've found that out months ago. I'll be treating with aquarium drops from now on. Having had aquarium's in the past this was the first thought I had.

Any reason that anyone knows of NOT to use aquarium drops??
