Ha ! There are a few of us who have not listened to the biologist
It does not always work out the way we planned after doing so
there are some threads here in the forum where fine screening filters were added to trash pumps. I think I can remember where Al(Fireishot) did something similar when transferring from one pond to another. I am not an expert on raising up back threads but u can google it with using pond boss in the search or just go to the past threads and do a little looking around. I am sure someone with better suggestions for searching will join in. And using grass or pasture for a filter is not good. There are quite a few fish like Green sunfish and Bullhead catfish just to name a few, that can and will survive that process and make it into the pond. Best of wishes for u and your new pond
