I have not found a source of relatively pure and inexpensive TEA in the UK.
Mistralni.co.uk is not expensive but is the 85% grade.
Scichem.com sell 500ml 97% grade at GBP 16.07+VAT + ~GBP 12 shipping but need an email request stating what it is required for and details of the buyer whereupon they will decide to supply it or not.

BTW, I don't think a little cloudiness does any harm,I always get it from the carbonate in Pyrocat-HD with no apparent harmful effect.
