thanks for the input folks...
I just got to thinkin' about how I do my own stuff and wondered if anyone had different routines for this, based around info that I was unaware of.
I generally test Nitrates before the PWC, which is typically undetectable, then I do my Ca, Alk, PO4, an hour after the PWC.
I only seem to get salt creep in my outer portion of the overflow box and in the sump.
It manages to always coat my fuge bulb, even though I don't see a whole lot of splashing in there... It finds a way to cake the upper edges of my sump too.
So I thought I'd check to see if anyone had ever heard of a reason not to place the salt creep back into the system. I had heard that it could burn the fish if it landed on them, but because I wasn't replacing it back into the main, I still wondered about any other possible negative effects.
Cheers,
Ryan
