Whelk?

They retail for $2 each. I sell them at $1.5 each. So don't be flushing them

Yup. Gotta be the ones for sure. Same issues except when I did my re-built the new tank my overflows and my emergency flows are all 2” so I am pretty wide open all the way. Get the odd one in the Gyre though.

I wonder how many beneficial life forms in our reef tanks have been wiped out for fear of having something bad.

I can see it easily with these snail as they look a lot like whelks.
