Hi
Obviously discarded bottle caps are the cheapest media for bio-filters but is any body using plastic ‘rawplugs’ Readily available here from £ shops

Whatever they are, you would want to be confident that a cheap plastic device was free of nastiest like BPA etc..

I would be suspicious of ANY super cheap material coming from Asia

I only know of Rawl-Plugs... being a rubber wall plug for hanging pictures etc..

A rawl plug is one of those plastic plugs you knock into a brick wall so you can drive a fastener into the wall.
Not sure of composition as there are so many different types.

Without knowing the composition its a bit hard to make the call.

I have made an,”EL” of a mistake! :oops: Must watch my ‘P,s’ and ;Q,s’
I did of course mean rawl plugs. Manufactured here in the UK from HDPE.
Normally available for around £1 for 500 but in the discount £ shops about 1000 for a pound. The small yellow ones would probably give the greatest surface area per cu cm. i might mix the colours just for fun to see if the bacteria have a preference.
