I have a new SPA (400 gal) and am trying to get "good water"
So I got a test kit. From Leslie's it seems to be a rebranded K-2005 and so had no tests for bromine or borate
I got some borate strips (nearly useless)
and a "FAS/DPD Chlorine & CC's test"
The Chlorine kit says for"
10ml test multiply drops by 0.5
25ml test multiply drops by 2
but the results are not aligned with the K-2005.
In fact they don't seem to be aligned with itself.
So I took some water in a 500ml cyl and created a 10ml and a 25ml sample from that single draw of water. (same water)
I added the R0870 powder to each
and dropped both until clear
7 drops for the 10 and 16 drops for the 25
7 * 0.5 = 3.5
16 * 2 = 32
Some discrepancy here. I suspected typo
7 * 2 = 14
16 * 0.5 = 8
Not helping here
I used the other agent to do the CC and the 10ml sample changed with 1 drop the 25ml took 3 drops
