Noooooooooooooooooooooooooo!!!!!!!!! Oh man that sucks! I'm sorry you had that happen, dude! At least you discovered it before every one was gone.
I really like UP sand right now, so a huge plus with no ammonia leaking and adding the shrimp in ASAP.
My mom used to say, "You did it before, so you can do it again." and Philosophers say, "The experience is in the journey."
Good luck to ya man, and congrats on successful operations.
