Ingrid, How long has your pond with the block been setup?
Also since you folks have the experience I don't, I may post a plan of my
pond/filter/piping system & ask for comments. If I can figure out how to
do
that. Can some one help there?

Dan for you best to demonstrate your design, you will probably need some
pictures. ASCII art doesn't work well in these proportional font days
anymore. Ahh the good old days, but I digress. I'd suggest you doodle up
some pictures of your plan, type up some notes and post them on the web.
Then post the link here so we can all surf over and check it out.
