Your aquaponic water does need to be free of chlorine and chloramines, as these are toxic to both fish and plants. If your local municipalities use only chlorine than you can aerate the water heavily (24-48 hours) which will off-gas the chlorine; If they use chloramines in the filtration process, then aeration will not work, and a de-chlorinator or vitamin c must be added to breakdown the chloramines into a non-toxic form.

Other options include collecting rain-water or using a filter that removes chlorine and chloramines, such as our Small-Boy KDF85/Catalytic Carbon and Sediment Filter, and our Grogreen garden hose filter. If you are unsure if you municipalities use this for their filtration process, give them a call; they would love to speak to you!
