I've had a Tetra sponge filter -- I think the name was "Brilliant" -- for about 6 years. It's the UU-shaped kind, with 2 sponges, if you know what I mean. I'd like to replace the sponges, which are rather worn, but Tetra seems to have discontinued this product line.
I see something called the Oxygen Plus Biofilter 2, which, judging from a photo in a catalog, looks identical. Has anyone used them and are they any good? Would you know if the sponges will fit on the old Tetra model? What other solutions have others who used/use the old Tetra sponge filters come up with for replacing the sponges?
Thanks,
Dinyar

Dinyar,
That Pet Place used to sell the replacements. The key is not to look for "replacement sponges." They sold them as conversion kits to modify their 20 gallon sponge (single) to a 40 gallon sponge (double). I was buying the mod kits and tossing the extra plastic parts just for the sponges. I love these filters! I have some Aquarium Technology filters that the company sent me to evaluate. They are bulky compared to the Tetra filters and the sponges wear out. For some reason loricariids eat the sponges as well (different sponge material). I'll stick with Tetra.

Dinyar if you don't have any luck finding any new sponges, I can probably dig up 3 or 4 to send you. I don't usually use them, and honestly the uplift portion works great for my egg pot creation for the synos, so I can't see me going back to them. I really like the Hydro line sponges much better, since I can power them with a powerhead, and I seem to be allergic to using air pumps for anything but egg tumblers or uplifts for eggs. I'm sure if I ever grow up and get a real fish room, I'll convert over to a blower, but for now, this is nice and quiet
