This hose adaptor will step down from 10mm to 6mm pipework and is ideal for stepping down pipework to feed a calcium reactor, kalkwasser stirrer or nitrate filter.

Most small pumps or powerheads have a 10mm outlet and you can therefore push a piece of standard flexible hose over the outside of it. Push the hose adaptor in the other end and you will immediately step down to 6mm which is suitable for airline or the Deltec silicone hose which is available from your retailer.
