Water motion in tank.

[StirCrazy]

hey Bruce .. I have been thinking of how to make the water ove for a while.. I have decided I don't want splashing around on the top but I just want a gentle change in directions (this way I don't have to worry about splashing water out of the tank [img]images/smiles/icon_smile.gif[/img] )
this rotating valve has my intrest as I could make the valve body out of pcv, and I am sure we have a piece of teflon I could chuck up in a layth and make the valve body.
which brings up anothr thing.. is teflon ok in a tank?
