I want to create filtrtion through the bottom using external filter eheim 2217. Inner hose has diameter 12 (internal) and outside hose has diameter 16 (internal). But I looked for bulkhead only with diameter 20mm (that side which for connecting with filter).
Do you know clutches for connecting 20mm pipe from bulkhead with hose has diameter 12 and 16?
In addition, that side bulkhead which being in aquarium must be has diameter 12 and 16 too. But how?
I don't understand..
