Well, my tap water suddenly has about 1 ppm ammonia in it, I called the water company about it they said they are now using chloramine, and that leaves the ammonia in the water as a side-effect. :;fru Didn't even warn me... RIP Panda Cories. Obviously, I can't use this water as is for water changes. I have 3 aquariums, a 75 gallon, 10 gallon, and 5 gallon. So, my question is, how do I get rid of this ammonia so I can do water changes? Is there a product I can use that will get rid of it, or a filter for the sink, or would I have to buy an RO unit? I don't want to buy the water at a store by the gallon just because I use so many gallons of water, I need about 30 gallons of fresh water a week to do partial water changes on all of my tanks. Any advice would be much appreciated.
