Removal of chloramine

So after having some unexplained problems with my plants I finally figured out i have chloramine in my water instead of chlorine which I believe could be causing me problems. What’s everyone using to remove it from your water? Thanks for your help!


I have both in mine and never caused any issues :man_shrugging: my water company uses both.

What is the issue you believe to be related :thinking:

Only way to get rid of chloramine is RO/di. And it will take a lot of di. I know from my days in reef tanks. The RO will reduce it to a levels that won’t harm plants


A small amount of peroxide (like 1 tsp/5gallons) will dissipate chloramines. I do this with my tapwater.


Did a little reading and basically this is what i found.

The point of using chloramines (a combination of chlorine and ammonia) is to kill harmful bacteria in drinking water, so it’s logical to assume that irrigating plants with chloraminated water will do some damage to bacteria in the soil - including bacteria helpful to plant growth.

The question is whether it’s going to do enough damage to cause plant problems.

Chloraminated water has been used for at least 90 years in the U.S. and abroad. If it was going to cause trouble in the garden, someone should have noticed by now. Here’s what one study from Australia’s Urban Water Research Association concluded:
“It seems unlikely that the use of chloraminated water for irrigation of soil-grown plants would have adverse effects on growth, whether the water is applied directly to the soil or as an aerial spray.”

Yes I have done a lot of reading as well and have read both it could be bad and might not be bad. Idk :man_shrugging:t3: I’m gonna at least get rid of it and see if it will help.

Wierd this cross my mind today. Was gonna ask Nikki anything and see if any n. American garden or yard plants was sensitive to chlorine since we have used in the gardens and around the house all my life.


I get this when I Google “do plants require chlorine”
“Classified as a micronutrient, Cl- is required by all plants in small quantities. Stomata regulate the release of moisture from plants so they can minimize water loss during stressful dry periods. Chloride is key in stomatal regulation.”

Im totally unconvinced that the levels in any tap water would be harmful to plants.
Maybe microbes but I don’t think it kill anywhere near enough to hurt if the soil was healthy to begin with.
In hydroponics where microbes are added and cant reproduce much then maybe, but in soil I dont think it hurts or with all the agricultural in the world it would be clear that it did imho…


I agree though I do not know :+1:

Our water was chlorinated for years …now (I believe) it is sanitized with Chloramines…anyway for years and years now Ive been watering my lawn and fruit trees,vegetables and ornamental flowers etc with this water… I think if it had levels that bad It would harm these plants…Yet I wouldn’t drink it… :laughing:…also and maybe someone can touch on this…Cannabis is a different animal…so yes it has specifics too. Ive always wanted to get an R/O system…but never got around to it…First year grow some 3 years ago I used municipal tapwater that I let sit out 24 to 48 hours in the sun…Then the next year filtered water from the fridge …Well at 50 dollars plus that filter got used pretty fast as well it being a pain in the butt to stand there and fill 1 gallon jugs at a time …So the next years (the last two) Ive been starting with rain water then just tap…No issues…so hmmm? Oh yeah well Im outdoors in fab pots…so Im guessing if it were indoors - hydro it may make a difference


You can neutralize chlorine and chloramine with Vitamin C. Sometimes I place a little organic matter in a blender and then use a little of the slurry to add to the water and let it sit a few hours.

I put mine in milk jugs and sit in the sun with the cap off for 48 hours or so
