[quote=esshup]Are you sure the basin is fine?
I'm not being "smart" but unless you can tell us how many gallons it's leaking out in a 24 hr period, my answer is you will need as many gallons going into the pond as is leaking/wicking out, plus what is evaporating, plus what the plants along the pond are transpiring, plus one gallon.
Water level stabilizes once it drops to the level in the pics, so I'm assuming the basin is sound. The bottom rolls into a "V" & runs the length of the pond, so this is a deep one when full.
Actually, I was asking how many GPM it would take to maintain it after the leak was fixed.
