I had my salt tested at pinch a penny today because I wanted to add some to my non-swg pool for the benefits talked about elsewhere on this forum. I have always had a great experience at pinch a penny and stopped going to leslies a couple years ago because they're such....well anyway. today there was a guy there who I hadn't seen before. I've basically dealt with the same two people for a couple years, but this guy I didn't recognize. so I ask him to test for salt and he says:
we don't have you as a salt pool, do you know what swg you have?
me: I don't have one I'd just like to know.
him: well if you don't have one there won't be any salt.
me: then you're not doing the test right because lots of stuff adds salt. chlorine...
him: well yeah but it will be very minimal. I know my chemistry.
he then puts the water in a little bowl thing on top of some machine (from the back this thing looks a lot like a kitchen scale). it took him maybe a half second to tell me my salt was 1700. I find that pretty significant, esp since that's even higher than I was going to make it by adding salt. not to mention its over halfway to the recommended salt guidelines for most swg's. so how did my salt get so high? is that normal? I wouldn't think so since so many people are adding salt judging from other posts. also, on 4/16 my TDS was 1,110, and today it was 2,700. it's always been around 1,000. what happened in a week to make it go so high?
I'm going to leslies later on to get another test and that recommended test kit. the rest of my numbers today were:
pH 7.8 (I've been battling rising pH since the pool was rebult in late 2007)
TA 119 (same as last week)
CH 399 (same as last week)
Stabilizer 75 (same as last week)
TDS 2,700 up from 1110 last week
I do plan on running my chlorine to the levels recommended on the chart, but my current test kit maxes out at 3.0 which is why I'm getting the new kit today. I also plan on using about half the recommended dose of PQ60 until it runs out. the pool looks great. thanks for any insight.
