I have found that the chloramines don't harm my plants at least. My water supply also uses chloramines and I don't do anything special to my water. I simply add my fertilizer to water fresh from the tap and go about water. I've never noticed any ill effects.

It all depends on the quantity. When the municipal water suppliers introduced chloramine - which is significantly less dangerous for people who work there - all aquarium fish in the areas was dead in a week. More of it - the grass was dying on the lawns. Since then - the amount was adjusted - and it depends on the treatment facility - at home - water is good, at work - AVs just wither and die - even if it is all Denver water. Probably downtown water needs more of sanitizing - the pipes are getting old.

Thanks for your comments.

It's mostly my house plants with pointy foliage, like my spider plants, that have tips that are browning just fast enough to raise my suspicions about my water supply. But no one on the house plant forum has tried aquarium conditioner. I'm seriously considering using de-chlorinator on my least favorite plants and violets (if there is such a thing!) and see how they respond for better or for worse...

I heard it helps.

For the control - you can buy several gallons of drinking water from the store - and compare which will do better.
