Well after deciding to go ahead to use it as is, I get an email today from aquariumguys.com saying that Fed Ex is coming TODAY to get the broken one and that a new one was sent today. That's all good, but I was right in the middle of my cycle! Nitrites were building up.... hope my cycle doesn't have to start all over again, and I wish I would have had more than a couple hours warning that Fed Ex was coming. Oh well... I didn't have to pay any extra shipping.
