[FONT="]The BIO-Wheels from the Penguin 330 will fit the AquaTech 30-60 Filter ... But it's a little bit confusing because you need to get 2 BIO-Wheel Assemblies, 2 BIO-Wheel Brackets, and 2 sets of BIO-Wheel Bearings. I have used the same names for the parts as appear in the list below from Marineland's web site.
After you get all these parts, you put one of the blue colored Bearings on each end of the shaft that runs through the BIO-Wheel Assembly, then you snap the BIO-Wheel Assembly with the Bearings into the BIO-Wheel Bracket, and set this whole Enchilada on the AquaTech Filter. Then you repeat this process to make a second Enchilada and put it on the other side of the AquaTech 30-60.
You'll need the following list of parts from their list. [/FONT]

This list shows that you need two of each item listed, this will give you 4 Bearings, 2 Brackets, and 2 BIO-Wheel Assemblies. You might want to add [/FONT]

[FONT="]Filter Box Cover for 330B[/FONT]
[FONT="] I don't use a cover on my filter, and I don't seem to need a cover. By the way, this filter will not work with just one Enchilada. One Enchilada won't turn, but of course two will.
Recently a local PetsMart had all these parts in stock. I got all the parts, assembled two Enchiladas, put them on my AquaTech 30-60, and it works fine.
Apparently the AquaTech and Penguin filters are made in the same building by the same people. The AquaTech 30-60 pumps about 10% less water than the Penguin 330. But this amount will probably not make a significant difference in most aquariums.[/FONT]
