Balance bottom drain and Oase Skimmer
 

What are the recomendations for balancing the two intakes? The skimmer has
1.25" line running to it and the bottom drain has 2" pipe running to it. The
skimmer does not work unless I restrict the bottom drain which is easy
enough with a manual valve. Is there a valve out there for ponds that has a
variable venturi? This would allow the 2" line to be restricted and adjust
itself as needed to keep proper flow.

Could you make the 1.25 line to skimmer bigger? Or maybe you need to suck
more gph? I have a similar set up using 1.5" on the skimmer with 2" on the
drain (as does the Demon Pond). My pond is running 1500/gph, Dpond
1800+/gph and skimmers are working great on both. ~ jan
