I'm getting a little of it here too. :icon_smile:

All my water comes from runoff from my garage and barn roofs to gutters that feed into rain collectors that filter out debris and finally feed to pvc pipes to the pond. Just good clean rainwater.

We haven't had a good rain at my place in over 6 weeks so this is a nice, slow, soaking rain for us. 1" of rain gives me about 4" in the pond till it reaches the overflow. Then just helps flush old water out.
