Well, after reading all the responses to my math question, I came to the
conclusion that the missing tris were, in fact, probably on the floor
somewhere, so...I whipped out my trusty flashlight and crawled where no
man had crawled before...through the stand and behind the tank (no easy
feat). Another once beautiful but now crusty Pappan Creek Tri lie dead
on the floor. Only one more to account for now. A lesson learned. I
cut some peices of a Domino's pizza box to fit around my filter tubes in
hopes of preventing another escape. Shit!
Thanks all
Jim
