Forgot Dechlorinator?

    I just did a small water change... but suddenly I’m questioning if I added dechlorinator to the last pail. I changed the water about 10 minutes ago and just added dechlorinator now to the tank to be safe. The fish are fine, enjoying the fresh water.

    Would 2.5 gallons of lightly chlorinated water in a 37G be enough to kill a relatively new cycle?

    Depends on the size of your tank. I really wouldn’t trust any untreated water, but I would suppose you’d be okay. I think if you added the treatment quick enough, you’ll be fine.

    Any idea how much is too much?

    Sounds like you had earlier pails with prime? If so, it's fine.
    You can always partial dose the tank first, then dose the pails also if you are worried about forgetting with many manual steps.
