I sometimes go through 2/3 socks while doing the sump, but yup. you're at least getting 90-95% of it.
I tried pumping back into my filter sock with the basic mesh filter socks that BRS sells (200 micron, I think) and it created such a cloudy mess in my sump... and then that shot up into my DT! It was terrible! What micron sock are you using to catch everything? Mesh or felt socks?
