pump arrived today, so had it up and running.
Straight out of the box it ran extremely powerful just in the tank, once I added the 4ft of hose to it and the spray bar it was absolutely useless!! Was equivalent to my Eheim 2028!!
So I did a test and worked out it was flowing at just 700lph, no kinks in the pipe or anything.
So I have now ordered an Eheim 1262 and keep that one as a backup
