I know this subject has been covered greatly on here but after measuring the diameters of various components I have some queries. After recently purchasing an APS 2000 external filter I discovered that although the hose id is 18mm, the spraybar right angle piece id is only 10mm with the main bar being 14mm, therefore greatly reducing flow. So I've been hunting for 18mm pipe to build one with but then today decided to measure a few other parts of the the system and discovered that there are quite a few bottle necks.
The 16/22mm UP inline atomiser has a 14mm id and the actual outlet on the filter also has a 14mm id. I'll be measuring the hydor inline when it arrives.
So surely this means that the flow is being reduced by the atomiser and the filter outlet, does this mean that the tubing doesn't need to be 18mm and the pipework doesn't need to be 18mm? Does the length the water is bottle necked for effect the flow?
Let me know if this doesn't make sense or I'm missing something
cheers
