Thanks for thinkin about if for me. the slots are located where they should be in the tank. However, i'm just gonna start over this morning with a fresh cart. I can't see through the hole in the two I was messing with this weekend and all the blowing and sucking isn't unclogging the hole either. (geesh...that sounded kinda nasty) anyway, I'm going to start from scratch this morning and see what happens.
If you can't see through it, then something got messed up inside. Out of curiosity, do you pre-fill your carts before you put them in your tank?
