I currently have an old Filstar / Rena XP1 canister filter for my 40 gallon breeder. The filters has worked extremely well over the years -- I've had to replace the rotor impeller assemble once, but other than that it's worked very well. But it's 10 years old and they don't manufacture it any more. I can still get parts for it, but for how long I don't know.
I'm upgrading to a 60 gallon and would like to upgrade the filter without losing all the media I have. The old Rena uses bio-chem stars and sponges. As far as I can see, most of the new canister filters use something other than the stars.
So my question -- Can I just put the stars and sponges into a new filter with the new media and gradually swap out the old stars when the new media develops?
Appreciate any thoughts.
