Chloramine - check your water source!

[phi delt reefer]

its important to remember that that most household RO systems are just running a low micron prefilter and a ro membrane.

as BBLinks article stated activated carbon will pretty much get rid of all of the chloramine. Most of your aquarium grade RO/DI units use atleast one carbon stage as part of prefiltering.

i guess the question is how effecient is the carbon block at removing chloramines and when would it be exhausted. IS there a hobby grade kit we can purchase for chloramine testing?
