Ok, so talked with my sister and think I have the test figured out.
I've copied in another review for a link on the equipment and also their results which are more in-depth.
I tested again on Saturday and got 78ppm K
. Still seems high though but this is only based on issues with the plants. More like what I would expect though. I had dosed 10ppm K
in the morning so was expecting something at least.
Cost of the kit was about $70 AUD (note Aus stuff is more expensive compared to US) but was however a lot cheaper than the couple of hundred dollars I had found for another test.
The test covers 0 to 774ppm (+/- 8ppm) so seems perfect for testing in FW
The test looks complex with 5 bottles and syringes but in reality was fairly easy to step through and figure out the results.
I did find it difficult to use the syringes. They are 1ml syringes and you draw 1ml. I found I had air bubbles that I had to tap out and muck around with to try and get 1ml exact. A 2ml syringe would be easier (or a dropper). The equipment is all good. Nothing fancy but does the job.
Safety wise you get a pair of gloves, particularly needed for the last two bottles. This is where mucking around with syringes and trying to tap out air bubbles needed some care.

If anyone has used this test would still be keen to hear from them.
