Ah - looking back at my notes, I was without mine for somewhere between one and two weeks. It goes without saying that this was a 'green' time in my aquarium. I would highly recommend water changes. Jeremy is quite helpful if you want to know details. Good luck! The new pump isn't as impressive looking, but it performs well.
Hey how long was the turn around when you got your askol changed out they want me to send mine in but I hate to be without it I run a Berlin type setup and it my main filtration dj
