To all of you with the Sicce pump.
today i got one pump from jason and and immediately i saw the problem .
if you take out the cover of the pump you will see the hole in the back of the cover it's narrow , on the original Sicce it's 28mm wide on yours it's 17mm this restrict the pump performance , when i swap my cover the pump pull 25LPM without problem . sorry i don't have picture no cam.... it's the same pump and this is the only problem .
there is option to increase the hole :
you can do it with dremel or if you want to do it more Pro you will need to use a Stand Drill and 1" flat drill bit , there is enough space to drill it without to damage the shaft holder .
After that you will be able to pull 25LPM without problem when the pump connect ot the skimmer body .
