Ouch!

Do you have something to keep the water moving at least? A robotic cleaner is best as they are virtually the same as a filter--one cycle with an Aquabot, Blue Diamond or Dolphin is the same as a filter cycle. I used that a few weeks ago when the drain cap on my filter cracked--I cut out the filter and ran the Blue Diamond.

If not, do you have something like a submersible portable sump pump, just to keep the water moving?
