Oh thank God haha I was told I had to let it sit, maybe I shouldn't listen to my lfs:/ except there's one Guy there that's pretty knowledgeable he has a tottal of 400 gallons of freshwater tanks in his living room
Some people do actually leave it sit for a while. I read somewhere it has something to do with allowing the gasses release from the tap water. But, it is not commonly practiced and I have had great success not waiting. Sometimes it takes me a bit longer like around 3 -4 minutes before I pour it back in (distracted with kids or something) and I have noticed that there's no bubbles in the bucket anymore.
My Mom told me I had to wait 24 hours before I poured water in the tank. Thank goodness I got online and did my own research LOL! She had fish back in the day so she didn't use water conditioners.
