strange results...

I'm in the process of balancing my water in prep for install of an SWG (Mineral Springs).

30000 IG plaster pool

Yesterdays results with Ben's kit were:

FC-0
PH 7.2
alk 120
cal 230
cya 50
salt 800


So using the Calc I added the following

.5 gallons of 12.5% bleach aiming for 2
480 pounds of salt aiming for 2700
2 lbs CYA aiming for 60

This morning results are:

fc 0
ph 7.2
alk 120
cal 230
cya 70
salt 4200

I repeated the salt test using water from a different part of the pool thinking maybe the salt I added was not fully circulated and I got 4000 the second time.

How the heck did my salt go so high? Might it settle lower?

I really expected to wake up today with everything perfect. Instead I have way too much salt since recommended max for this unit is 3200.

I run the pump 24/7.

Any ideas?

Jeff

P.S. Thanks to all who provide such wonderful info on this forum.

On the salt, do you have an issue fully resolved version of Ben's test kit?

There was a problem with the salt test, from what I've read.

The mineral springs unit will work fine with that high a salt level. running it at the level your were aiming for will actually shorten the cell life.
As far as the testing results I suspect that your are probably much lower than the tested level. there have been some problems with the salt test that Ben is working on to resolve. Just as a backup have your salt level tested at a pool store and see what they come up with.

After reading about the "tip" issue I retested, carefully wiping the tip after each drop. Sure enough, I now get a test level of 3000.

So I finished the SWG install and turned it on. The readout is saying 2900, so the two results seem consistent enough.

Thanks so much for allaying my initial panic.
