ive been setting up a wash rack for RW, the basis is you soak RW to set the internal ph of the medium to 5.5 but this dont wash out
all the grime and particals that is in RW and from all the RW ive soak I see no reason to even soak it!
so I got a rack and put a 5 gal bucket of ph 5.5 water in it and bellow is another 5 gal bucket with a dwc insert the basket type,
theres a pump in the upper bucket feeding a line down to the lower one. I fill the basket with RW and blast it with the above water.
the lower bucket drains to a floor drain.
this all seems complicated but once setup there 0 soaking just wash then use
