Question: Won't letting tap water sit for a few days remove chloramines?
Answer: No, letting tap water sit for a few days will not remove chloramines. The common practice of filling a container with tap water and sitting it aside for a few days before using it in an aquarium works fine when chlorine alone is present, because it dissipates from water rapidly on its owe, but chloramines can stay in the water for weeks.
