OK, I intend to install a bottom aerator but want a fountain for looks. Do not wna to pay the high prices for a boxed rig. My thoughts to buy a swimming pool pump, place the intake under my pier, and run PCV pipe on the bottom up to a surface head. Question, I would like to have a fountain head other than a PVC cap with holes drilled. I have not been able to find just the fountain head for sell. Any clues?
