Anyway here is my new beananimal overflow. It is on a 26 gallon bowfront. 3/4 inch plumbing. I know the plumbing is small but it should handle 600+ gallons an hour at full siphon and right now I only have 200+ circulating till I get a new pump. I am wondering if my "straight" T's are the issue. I did not realize most ppl use a sanitary T. These T's have a 90 degree elbow like bottom with a straight portion coming off the top. Like the one here:

I attached pictures of my set up. Middle pipe is full siphon with ball valve (wish I had just bought a gate valve), far left is secondary. Pls help!
