Between the added restriction of the T and the fact that I will probably have to throttle back the pump with a valve, you are probably correct. The 3000 does about 550+ GPH at 4ft of head and the RIO 1700 does about 350GPH. I'm not sure what the 1/2" durso overflow can handle. Hopefully I will soon be able to check that out.
