So I had this old topfin filter lying around and it looked and ran terrible, so after a few tweaks and weaks, I managed to get a much more powerful pump attached to the propeller thus increasing GPH. I extended the area for media too. I added bio media max (fluval) and some cotton.
BEST HOB!
A good idea for any horrible filters you have lying around!
