Just to let you know there is a typo on page 70 that could mess you up. I talked to the author the other day and he cleared it up for me. You want to cut your cup rings from 3 inch PVC not 4 inch PVC. (But you still cut 4 diameter inch rings) Also the axle is 3 inch PVC not 4 inch PVC.

Also on the top of page 71 right hand column, it should say "Use the specification provided in Appendix C Diagram 4, " not Appendix C Diagram 4.

Any idea if you will go with option 1 or 2 to power the biodisk filter? I'm going with the all air option 2 vs. a water pump as if you go with the water pump you have to add some form of aeration. With option Option 2 the air powered filter rotation you can kill two birds with one stone and don't have to run two motors.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
