Sorry I can't answer your question but I was considering buying one. How do
you like it?

I have a tetra canister filter. Seems like it's been about a year since I
cleaned it.
Last time I disconnected it and simply cleaned it out. I'm wondering if I
can some how reverse the
water flow to clean it out? I assume it has good bateria at the bottom,
but
I'm sure there's lots of
gunk down there as well.
