Hi

Just bought a new Fish mate Pressurised UV-bio filter to replace my old
gravity box.
However my pump doesnt seem to want to work at all. It doesnt seem to be
sucking any water up. Weve cleaned it all out but nothing !
Is this anything to do with the new filter?
I know the pump is really old (think about 10 years maybe, we inherited the
pond when we moved in) but dont really want to have to buy a new one yet.

Any ideas anyone??

Cheers

Cheryl
