Sounds like a plan.
One last idea, if you have a creek, you could, use an Ultra Violet light water bacteria killer.
12 GPM flows at 55 watts, @ $200.00.
LOL. Its not a LAST idea it was my first. LOL. I am still contemplating that for sure. Since I have a recycled system I might have to pump that treated water into another holding tank first? SInce UV works best when fed water slowly as I recall.
Also, where can I find more information on that $200?
Creek is 100 ft from the tanks. Winter could cause some issues, like insulation on the pipes. IDK. The only time I am not normally raising trout is June through September.
