Hi John,
Thanks for the tip. Do you have to buy a 'cartridge' for that model, when
it runs out? I had a vague idea that some phosphate dosers can be refilled
with generic phosphate balls (which would be useful if the cartridge-maker
goes bust).

Yup that one takes a cartridge.

Some like the Combimate, take balls loose. But having had one of those
in the past I was less impressed with it. (more of a hassle to top up,
restricted flow a bit more, and rattled a tad in use). They are also
quite pricey.

There is a moderate chance you could refill one of the BWS cartridges if
needs be.
