I just installed a Weldon pump. On Weldon web site they recommend there 100 micron before pump and there 10 micron after pump

That doesn't make sense to me but I haven't messed with filters much. This is what I found using google:

Which Is Finer? One Micron Or 100 Microns?
It's easy to get confused when it it comes to filters. It's easy to imagine that 100 microns would be a better filter than 1 micron, but this is the exact opposite. Again think in terms of the hole size in the filter medium. If a micron is a unit of measure, then ten microns must be ten times bigger than one micron, and one hundred microns must be ten times bigger than ten microns.

So, if a filter is 100 microns, the holes that do the filtering are 100 times bigger than those found in a one micron filter.

Filtering In Microns Made Easy
Still confused? Okay, so I'm not a scientist and my explanation may be a little off, so here's a quick guide:

Coarse Filtering = 500 Microns, 200 Microns, 100 Microns

Medium Filtering = 50 Microns, 20 Microns

Fine Filtering = 5 Microns, One Micron
Correct!
