I guess the filter is taking in air somewhere...that's my best guess, bc that's what it has been doing since I got it. The other day, I took the tubing off, started and primed the filter lower than the canister, made a big mess, but I got it going without air bubbles in the tubing. Now it's stopping and starting again. I had to turn it off for a day or two before that bc of the grinding noise it makes when it stops. I was afraid something inside would break.
Plus, the basking bridges aren't working anymore. The suction cups won't suction to the glass so when spots tries to climb on, the bridges fall off the PBS support and float to the bottom of the tank. I use two like these:
