OK - get the picture. Fluorite? You must be joking. Round here, anyway.
Laterite you can get - at around £15 (what's that? about $20?) for a small box. So until I am Minister for Health rather than just working for the NHS, I'll pass.
But I've found this stuff: http://www.lifeforceonline.co.uk/ph...hp?product=877&group=306&start=&search=&n=&o=
Got to be better than nowt so I've got a 15kg bag on order for my new 36x18x15. Anyone had any experience? My inclination is to think it'd have some of the benefits of fluorite but would need iron adding to the water column.
