New Filter Needed... Reckon I Want To Go With Same Again?...opinions Welcome..

If you like the PF1, get another. It has the advantage that you can just move the media into the new filter without having to persuade it to fit with a pair of scissors.

But if you feel the PF1 will not last long - the first one has already stopped working but you don't say how old it is, it could have been running perfectly for years  - then this is the chance to try something new.
Should you decide to opt for a different filter, the smaller Eheim Aquaballs or Fluvals U series are good makes. Having done it myself, it is quite easy to get the wrong shape media to fit in the Aquaballs.

Thsnkd for the thoughts. think I might go with PF1 again this time for simplicity (it had been around a cpl of yrs, could have lasted longer though   )

The aquaball looks interesting, I like the all round intake, not seen before as always thought about trying the fluval.... I will take the time to investigate media etc
