Auto top off " Jeorge"

Jeorge I have tried to respond to your email, but it keeps coming back
"no such user". Any how if you read this you will see what I was
trying to say. All you have to do is break the hot wire of the power
head with our float switch. That is cut the hot wire of the power head
"the one with the small prong" and tie each end of the float switch to
the cut wires. Place the float switch in the water that you want to
top off. This will keep it within 1/4 inch. Make sure that you do not
exceed the rating of the float switch, Aqua Tech power head works
good. I think it's the 190, which is fine for top off, and Wal-mart
has then for about $18.00

Thanks David
