Running to many heads, too deep, will tend to cool down the water with no where warm for the fish to go. Plus, we have an otter problem, limiting the access to one opening that I can see from the house, makes me feel better.

For start up, remember to start slow, one head, adding time to the short durations gradually each day.


Our climate is similar so good advice on proper technique. Do you have clay and do you do any water testing? Thanks.
