Pre-Filters - ideas? anyone, anyone, Beuhller?

[wade]

I am considering DIYing some pre-filters for all of my sump related pumps (ca reactor, media reactor, etc).  In looking around, I have not found anything retail that would seem to work as well.  I would like a very open cell type foam (the really course stuff like you can get pre-made for the Mag drive pumps).

 

Has anyone done anything like this?  The inlet pre-filter would need to have a gap around the actual intake, be easy to remove and clean, and be sturdy enough that the pump won't collapse it and restrict water flow mechanically.

 

Sources for parts? Ingredients?

 

I'm considering maxijet1200 and/or Sicce (0.5 or 1.0) as feed pumps (my last mj1200 died).

 

Thanks for input!

i usually take some foam from some random packaging or use the stuff from the sponge filters....cut with a razor blade it actually works pretty good
