    I removed the elbows and now im alot happier with the return flow. Its amazing how much flow one can loose from a few elbows.

    if you really need to use elbows, rather use 2 45degree elbows together than one 90 degree elbow. Will still restrict the flow, but less.

    I replaced the hard plumbing on my return line with flexible hose. Amazing the difference. OK, flexible hose do not look so good or neat. But at the end of the day it works better.

    on my own personal tanks ive always used the cheapie flexible piping/tubing ... as @RiaanP said,aint that neat but works very well..yes i know it doesnt compare to the looks and this and that..but id rather have something thats easy and works instead of looks or a trend... :)

    what is the inside of your return. In the tank. Just the fitting?

    If so, come around, I got the solution for you. Will show you it in action.

    Noticing a difference with a Tunze pump, imagine the difference with a cheap crappy pump!

    drain to 5cm below the inlet.
    But as you said if it is working. Why change it.

    Would a flow accelerator attached to the end of your return nozzle help?

    Yes, but then you end up with the nozzle to far under water and a lot of water head siphoning back to the sump when the power goes out.
