Filtration / ULNS

Well, my reactor landed 2 days ago and after a 9 hour round trip to Kilmarnock and Prestwick I had waited long enough and another few miles to brother markis would not kill, so off I went to pick up the pearls

Thanks to Martin for the bulk buy
Now I thought, Im to knackard to start messing at this time of night...... then I thought sod it.
Ok, so I ordered the 1tr reactor to hold around 150-170ml of pearls. I was using the phosban 150 with rowa in there and wanted a reactor...
