I use the Guten bazooka filter fitted to the pump inlet as I was sure it was inadequate for it's proposed role, and now I'm using one of WEAL's helixes on the tap.
Do you cover the overflow tube of the malt pipe with the little plastic screw on thing when adding grain?
And do you adjust the recirc pump flow so it doesn't go down the overflow pipe.
Yes I use the white plastic cap to prevent grain going down the pipe
