The Zeigler Silver I have, most of it will float for a good day or so, but by then it expands quite a bit, but still floats. Could be the fat?

Water has been in the 40's for a while now. I blocked off the inlet to the sump so the feed won't get sucked in. Every morning I toss some in and it's gone when I get home. Nothing in the sump, so they have to still be eating it. I haven't seen a HBG in weeks now. There are quite a few places to hide and I see the inside bottom of some 4" PVC pipe is really clean compared to the sediment all over everything. I think they like my randomness of dropping in PVC pipe sections.

Last HBG I saw was a brute!, so I'll just let them do their thing until I tuck them away in the basement for the winter.

I ordered a bag of Optimal (latest run stuff with the 3 sizes) going on 2 weeks ago. Was told back then it might be ready to ship sometime this week. I said no problem, not in a big hurry.
See how it works with YP.
