yup i have a 1/2 system and dont want to use redusers or mess about with tubeing over tubeing i wud like the ddc as its a 12v pump thus not needing switches or relays to oparate and i feel may actualy be better then my presant Eheim 1048 also in the french reveaw of ddc there was a statement about restriction of inlet so maybe there may be a little flow to be gained useing 1/2 barbs after all
"most certainly the DDC is foolish for a 1/2" system"
i dont feel that is true
(edit and hopefully the ddc dont leak like the d4)
