Maxspect Gyre Mesh Covers for a XF250

Hello-
I am looking for replacement mesh covers for my two maxspect gyre 250 pumps. I noticed that you do that the product available on the CoralVue site however I have a couple questions:

http://www.coralvue.com/maxspect-gyre-mesh-covers

- Does this work for a Gyre 250? There seesm to be options for the 130 & 150 only
- How many mesh covers come in the package ?

Thanks
