bio wheel not spinning

[johnm]

I noticed that my bio-wheel doesnt spin when i have a sponge cartridge in the filter. I took it out and the wheel turned. Any thoughts on how to handle this? I may just need to replace the sponge filter as it may be slowing the outflow down also.

Is the sponge clogged....the wheel needs a certain flow rate to spin

Easy... just clean it...

Take a few cups out of your tank and in to a bucket. Then shake and lightly squeeze the sponge in the bucket to loosen up some dirt. Finaly put it abck in your filter.

Should work like new, but still have bacteria

i clean it regularly by vigorously shaking it in a bucket of tank water but it still doesnt rotate

Could be you filter need to be cleaned out? Water flow could be slow? Or you have some missing parts?

I have the same problem. I have a Penquin 100 on a ten g. It never spins even without a filter. I have 5 of the 150's. They spin fine with new filters but if I add floss between the filters it slows down and eventualy stops untill I clean the filters and floss then it's fine for a week or two. Don T.

I'll clean the entire filter today and see if this helps. Ammonia is still zero though.
