Stream pump as prefilter

Putting too dense filter material in filter can have big hit on output so i thought how to use stream pump for prefiltering.
Powerheads are used for (pre)filtering but havent seen stream pumps in that role.
This particular pump has a 5000 L/h (1250 gal/h) output and its a shame to not use it for something more than circulation. So i just took piece of women stocking with both end open and pull it over pump. Stocking need to be twice a longer than a pump to make pulling off easier and it will make returning of junk in water volume much harder. Output part of pump must be clear.
The part of stocking that goes towards the front of pump can have some kind of elastic tie to not allow sock to pulls off the pump due to stream and it will help during pulling sock off the pump with closing front end and keeping junk in sock.
Drop in output of pump is not noticable.



For better results, some better filter material would be nedeed, such as 100-200 microns pre-filter sock . I ordered one to see how that would work
