I use a britta when they are babies which probably doesn't do a thing other than make me feel like I'm doing something. I have read conflicting reports of whether or not chloramine kills beneficial bacteria in the organic soils I use. I believe that it does kill some of them, but not at a level that is detrimental to my grow. I refuse to spend any money on a filter or water conditioners until I see with my own eyes a problem.

Chloramine - Wikipedia, the free encyclopedia
wow... there is always something isnt there? I read a bit further and found that the chloramine is easy to get rid of too.. the process is sort of funny... you add chlorine to break this stuff down and then you get rid of the chlorine by putting it in the sunlight. I feel like I am on a merry-go-round.


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.
Thanks for the added info on this new thing to look for as I inspect my water content. Any info on why they use this instead of chlorine? Is it cheaper because it doesn't evaporate?
