I have been looking for suitable test kits in the UK and have found HTTP://www.pro-swim.co.uk they supply LOVIBOND TEST KITS and PALINTEST TEST KITS, their is no minimum order but their is a delivery charge for orders under £500. I am going for the SP620 Cyanuric Acid Kit at £16. Palintest have a min order of £50 but if you go for the SP315C this costs £55.70.
Hope this helps the UK members.
My apologies if this has been mentioned before.
