Can't wait to see pictures. You could get a real neat effect with that pump angled up to create an upwelling water surface, but somebody smarter than me should comment.
It is winter here again suddenly, but I am making some progress getting my stock tank pond going. The last few nights I have been repotting my marginal flowering bulbs. I plan to use this tank...
Agrimaster 144-gallon at Farm & Fleet
There is a lot of great flowering stuff that you can get going in a pond like this.
