Sorry to double post but I have a small update on my setup and a question:

I have received my ek supreme plexy top. Looks sweet! I have not purchased the barbs and here is what I came up with:



Industrial barbs with teflon and oring. You can see the teflon through the plexy.

I have a question though. I tried hooking everything up and there is flow but it is very modest! if I hold up (in the bathtub) the tube coming out from the ek supreme I get a steady flow of approximetaly 40cm before the water falls back in the tub. Is this normal? Is this block that restrictive? Without the block the water coming from the pump outlet would move (even if submerged) the whole volume of water in the tub. Something more like a jacuzzi rather than a normal pump. Ideas?

P.s. comments on barbs are welcome!
