I was changing Spike's water today. Usually as long as the water level doesn't go past half the intake tube, the filter is fine. It didn't stop when I was pulling out water. This was only a 40% change.
I stopped when I was putting IN water. I was pouring in the corner right next to the filter(so as to not disturb Spike's cup).
Has anyone else had this problem? Top Fin still have lifetime warranties on their filters correct?
I'm thinking about trading it in for the MarineLand Penguin 100
