Thanks to everyone for the very nice comments and congratulations. It's so nice to read that others besides myself are benefiting from the content. I guess it is kind of a big deal to split a thread - indicates that there's some value for more than just the thread-starter. White Russians ("caucasians") for everyone!!

John - I'll look into the Eheims, great suggestion and excellent point about less precipitates accumulating on a cooler surface. Hopefully it'll fit in the return section of my sump. That clam thing is weird, hu?
