chloramine..if you use tap water you want to read up on this chemical

this shit fucks up your grow it does not evaporate in 24 hrs like chlorine...the way you can tell if your tap has chloramine in it is in a five gallon bucket the water will look yellow...if your in one of the citys that uses it dont use it unless you want your plants to go to shit

how do i get a mod to delete one of theese threads...the thread posting is messed up more than me this morning lol

 

[Guest]

how does this affect the plants overall? If you get a RO machine will all the chloramine be removed? This is kinda sketchy...

 

[Guest]

yes a ro filter will remove it...it affects your plants the same way bleach does it wipes out your root systems beneficial bacteria(immune system if you will)...ic mag is screwed up today..this posting is jacked up

 

[Guest]

man...this explains alot...been using tap in the city for a while now....besides havin allergies and stuff...my plants would always seem to have a pinner root ball when i pull them from the pots, which i thought was really weird....the chloramine must have been killing off the roots....what a nightmare....and scary..gonna have to get a RO machine right away...no more tap for me thank you....thanks for posting this...

Tests have shown that chloramine, which is produced by adding ammonia to chlorine, can remain in the water for several weeks. This means that if you don't remove it completely it could go on harming your plants.

Welsh Water has become the latest in a line of water authorities to switch to dosing with the disinfectant chloramine, rather than chlorine, and has just started adding the chemical to tapwater in the Anglesey area.

Welsh Water told Practical Fishkeeping: "Following a �500,000 upgrade of the Alaw and Cefni Water Treatment Works this year, new equipment has been installed at the plant to add chloramine to the treated water, a change from the traditional use of chlorine, to help maintain water quality throughout the distribution system. The system has now been fully commissioned."

"We produce top quality drinking water at our treatment works, and want to make sure that we maintain this excellent quality right to our customers' taps. Chlorine has been used to disinfect tapwater for many years, but it does not remain in the treated water for more than a few days. Chloramines, however, can remain in water for a longer period, ensuring quality is maintained in supply for a far greater period of time."

Tests have shown that chloramine, which is produced by adding ammonia to chlorine, can remain in the water for several weeks. This means that if you don't remove it completely it could go on harming both fish and filter bacteria.

Unlike chlorine, chloramine can�t be removed by boiling, leaving the water to stand, aerating it, or spraying it into the aquarium or pond through a hose, and unless you take the appropriate steps to get rid of it, it will remain in the water.

When given a sufficiently long contact time (5-10 minutes) chloramine can be removed from water using a combination of activated carbon and zeolite. Some RO units will remove it, when equipped with carbon filters. However, the easiest way to remove it is to use a chemical water conditioner.

The majority of popular dechlorinators are based on an ingredient called sodium thiosulphate, in varying strengths. When added to water containing chlorine at the correct dosage, these water conditioners convert the chlorine to harmless chloride ions, making the water safe to use.
Several ingredients used in other dechlorinators, including sodium sulphite, sodium bisulphite and ascorbic acid, as well as sodium thiosulphate, can also remove monochloramine from tapwater.

However, many need to be used at double the normal dose for chlorinated water, and the vast majority of them also leave behind the ammonia part of the chloramine molecule, unless an additional ingredient has been added to take care of it. So, while you�ll get rid of one toxin, you could potentially introduce another simply by treating the water.

Two products, Kent Ammonia Detox and API Ammo-Lock2 are capable of removing chloramine and the resulting ammonia. The vast majority of other dechlorinators do not do this.

Although many fishkeepers, and even aquatic retailers, may be unaware of it, over 10% of the UK's tapwater is now dosed with chloramine.

what if you treated tap with one of those aquarium chloramine removers, is that safe for you and your plants?

Good thread....My experience and research has me convinced that GAC (granulated activated carbon) filters remove chloramine, but RO filters (membranes actually), used alone, will not remove chloramine. In fact, RO membranes do not remove VOC's (volatile organic chemicals)....GAC filters remove organics

If the goal is simply to remove chloramine (and other VOC's)....a Brita filter will work just fine....

brita huh...sounds good but they are a little slow...what if you need a lot of water...

this may indeed be your problem...

but do not go automatically assuming it is because it sounds like it fits your situation.

Brita has a one gallon model available, just leave the lid off, and set it on a counter with a bucket below it. I ran this way the first two years here, then dropped it this year because the water does not need filtering in my area. I set it up in the kitchen, and just poured a pitcher of tap water in every time I went through the kitchen, no worries.

Get the aquarium chlorine remover drops, they'll neutralize chloramine as well. The chemical in these products is sodium thiosulfate, should you like to acquire it by some other means. Dechlorinator is safe for your grow, so no worries there either.

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.

There is an ongoing discussion on APD about Chloramine, and how much of a threat it really represents. Here is some more info about treating Chloramine with a product that only deals with the Chlorine:
EPA Guidelines set a maximum allowed level of Chlorine of 4ppm. Most water supplies target 2-4 ppm Chlorine. Note that 4ppm of Chlorine is actually 5.8ppm Chloramine. (The Chlorine is 69% of the chloramine molecule, ammonia is the other 31%) So, with a possible 5.8ppm Chloramine, you have 4ppm Chlorine, and 1.8ppm ammonia.

Assuming a 100 Liter tank (about 26g):
If you do a 10% water change, you would end up with .18ppm ammonia.
A 25% water change gives you .36ppm ammonia.

Ammonia toxicity varies based on pH and Temperature, but in my book anything more than 0.1ppm ammonia is too much.

From a 1995 post here by Neil Frank:
"Then, it follows that short-term concentrations of total ammonia should not exceed 0.1 mg/l and longer term (4-day average) concentrations should be less than 0.02 mg/l."
