If I expelled my detritus from the sump, it would go back into the tank, where I have mucho current to expell it into the sump.
Not sure of the senario here.
Over the years, I have tried having the skimmer remove detritus from the sump. Yea, that works well and I have run some large skimmers. So I guess let it build in the sump with designed baffles to contain it for cleaning or use socks. One way or the other, one has to manually remove the detritus.
So I,m now trying socks, for the first time in 35 yrs.
Cleaning them is a pain but no worse than trying to get that crap from one,s sump. For those that use bleach in a washer, {my wife,s going to love that one}. I wonder about using bleach to clean something going back into my tank. However I see some here and many on RC doing such.
