For what it's worth, my water clarity was very dark (and mostly still is) when I tried to get them pellet trained. Sorry bill, no secchi reading, I'm not that high tech yet. I would guess 2-3"???

I will say that when I did try pellets on those old Bg, that it was pre pondboss and I didn't know about hydrating. Just tried it as the hatchery told me to. Tried for two months and nothing happened. Throw a worm or grasshopper in there, and they sure came for that.
