Yep!I was curious to see what my filter wasn't getting.I put socks on the returns and in a few hours their were 5 or 10 live sweat bee's in each sock.
and not much else!I have seen the bee's floating on top of the water so Im thinking "floating" is the key word here.
I have a Pac-Fab Super Flow sand filter.What would make small "floating" objects not get caught in the filter and come out the return:?: :?:
