Thought I would add an update here. I ordered a test kit from nqpooltestkits.com.au last year and like many was disappointed by the time it took to arrive (about 8 weeks) and the lack of response via email in that time (3 sent, no replies I recall). There was a letter included in my delivery saying sorry but their web guy had messed up and the order process did not work properly.
So this spring I decided to order some refill reagents. Same deal, no goods after 4 weeks, no communication. I'm calling leopard (has not changed it's spots). I see now they haven't renewed their web security certificate, maybe they have finally been wound up which was inevitable the way they operated.
Anyway after the time and money wasting with NQ Pool Test Kit I moved on.
I tried the Clear Choice Labs Kit. Ordered on a Saturday, received tracking advice Sunday and had it at the door Wednesday (cross continent). I feel the kit is better in a number of ways, the test instructions cover possible variations and causes of variations and it also includes standards for some of the tests so you can check/confirm your own techniques and reagents. The downside of the kit I feel is all the components are in zip lock bags to separate them by test which just adds a bit of time to the process. It would also be handy to have the target ranges for each chemical shown. I had emailed a tech query to them one day, helpful response within 2 hrs, can't complain about the service.
