1st Time Test Results

Salt - 6000

I did the sale test twice and seem to end up with a very incorrect number. I should be around 2700 and my pool store says that I am near that. Ben's test is giving me that higher number. Could I be doing the test wrong?

Nope, I did the wrong thing with the kit . . . and have been driven to distraction trying to figure out what that 'wrong thing' was!

The white bottles I used for the SALT#2 and the CHL#1 are (it turns out) very prone to acquiring a static charge* . . . and this charge causes the dropper to release smaller than expected drops, which in turn causes the high reading errors. For some reason, the silver nitrate (SALT #2) is affected more than the FAS (CHL#2).

Wiping the tips with a clean damp tissue before testing will often remove the charge temporarily. If you'll wipe the bottles with a paper towel dampened in hair conditioner, and then let them dry . . . and then wipe the tips with clean damp tissues before each use, you should get good results.

*I guess I've been lucky before. I've seen cautions about static charges in the instructions for various test kits over the years, but have never encountered knowingly encountered the problem before. (Maybe I had bad readings, but just didn't notice?)

So, I have tried your method of wiping each tip before using and my salt test is much better but it is still running high. It is saying my salt level is at 3600. It should read around 2700 or 3000 at the most. That is what my calculations indicate from my salt addition as well it matches what the pool store says. Any thoughts?

I am having the same problem after applying hair conditioner to the bottle as an anti static and wiping the tips....the salt test is usually about 700ppm above what I know the salt level to be from a goldline salt meter calibrated with a 3200ppm standard from goldline and also from the aquacheck salt test strips that consistaly test within 150 ppm of the goldline meter. Ben is still working on fixing the problem and I believe he is getting close from the last PM I got from him on the subject.

Great! Thanks for the update. I just hadn't heard anything from Ben recently. Hopefully he will find a solution soon!

One of the reasons he has not said anything is recently is because he has been busy trying to get the salt test straightened out and get the shipping of the kits straightened out (USPS has caused him all sorts of problems!). Rest assured that he is working on both issues!
