John,

For your size pond the recommended would be 80 watt, which is 2 - 40 watt
units in manufactured series. It has a recommended flow rate of about 20
gpm max for the dwell time/exposure to work. The cost of two 40 watt units
is less than he price of one 80 watt unit. I would try one and if it worked
save the cost of the second. If not, then add a second.

thanks Rich
Im gonna have to learn to read again
when I first started this ponding I was used to GPM pumps and kept
interpreting gph as gpm
Now its the other way around I keep reading gpm as gph guess its a
side effect of OFD
