Do you do anything else before putting it through the berkey? Pre filter?

Collecting rainwater for the Berkey, comes out mostly mud free when the deluge is heavy https://video.nostr.build/82e6ec78b854b8b934660126d53b8f989bcb60c325d1830601488397fa448f17.mp4

I dont bother any more, just try not to tip any bits of grit in there. The compartment isn't sealed so sometimes dust etc drops in when I lift the lid, so it needs rinsing out every now and then anyway
