Hey no problem, Ken's Fish has some great prices and ships quick too. Definitely let us know about the difference in pre-filters, I'm curious since I have only used the #1.

You may be right, especially considering the #3 uses a reticulated sponge. Now that I think about it, I use the #3 prefilters on my Magnum 350 in my plant tank and I use two of them on the Fluval 304s I have on my 125g Tanganyikan tank. The reticulated foam on the #3s are much more porous than the #1's. I can go 2-3 weeks without cleaning the pre-filter on my plant tank and I've went up to a month on the 125g. I still have #1s running on a couple of 10g tanks and they do need cleaned every couple of weeks but they are now on fish/plant tanks instead of Shrimp only tanks.
ATI's Site has a couple of pics and a better explanation of the filters than I can provide
