After studying this situation i might have another option. There is a creek behind my pond about 100 feet away. I could maybe put a 110 circuit pump and connect a hose to the creek and drain it into pond with a switch i already have on my porch maybe?
the ESS-13 stuff they seem to want about 4k for 4 barrels of it. Interestingly they will guarantee it after you about 1 thousand for another 4 barrels should the first batch not work. Thats pretty hefty pricing but nice on the guarantee.
