Got the 1/4hp pump on the center drain up and running and quickly maxed out what the RDF could handle. The overflow system handled it no problem with the knife valve not even open half way. This set-up could easily support a 15,000+gph RDF before it. returning to the pond through a single 4" line.
Got both 1/4 and 1/3 hp pumps dialed back about 50% each on their outlets and this seems to have the KC 30 running at max capacity through the screen. So thats about 8,000gph.
Interested to see how it looks after 24hrs.
