'Closed loop' sand vac

[psumms]

Having a daily auto-water change, I very rarely do a manual water change - but occasionally give a vac to my sandbed and filter through a python syphon to a large fine filter sock in my sump. Works great, although it clogs after a few minutes. Wondering if anyone has a better solution for this?

 

[TL1]

I do the same with a sock in the sump, and it does end up clogging and I end up taking out more sand than I would prefer... following.

Same here. The only solution I have found is to replace the sock when it clogs. When I vacuum sand I have 2-3 socks prepared in advance

Perhaps some kind of settling chamber prior to the sock?

was thinking about this, is there some sort of strainer that could be used pre-sock

Resurrecting this thread for any updates. I am thinking of a couple of options and would appreciate any thoughts. First, how is the python to filter sock in the sump working for anyone? Second, would running the python into a canister filter and then returning to the sump work better to justify the $$$ of a small canister?
