its probably just over 1/2 acre with an average depth 3ft (8ft near the center and damn).
There is no electricity anywhere near the tank, unfortunately.
I should not have put fish in it without making sure the watermeal wasn't going to return.. i had it in my mind that the grass carp would control the watermeal... was told by someone that they were the ticket.
it's been about 3 weeks since we applied the fluridone, the watermeal looks a little yellowish, but thats about it.
