I started using the magnetic stirrer this year and just assumed everything was fine. I still use my Taylor reagents etc, just with the auto stirrer now. I assumed I was doing everything right.
In the past I have cheated a bit with chlorine especially. If I knew I was generally around 4 ppm chlorine I would just go ahead and put 15 drops chlorine reagent then drop by drop after till I was there.
With the magnetic stirrer there is no point because I dont have to stop, put my chemicals down stir.....
So earlier using the magnetic stirrer I got 6 ppm fc, and wanted to verify with manual stirring; I got 4 ppm. 30 drops needed for manual stir vs 20 drops needed for magnetic.
I tried different things to figure out what I was doing wrong. I ensured both 25 ml mark are the same. I then put 20 drops in for me manually stirring, noticed it wasn't clear, and dumped it in the magnetic stirrer. It still took 10 more drops.
Finally, I did drop by drop with me stirring manually, until I got to 20, and it still wasn't clear. It still took 10 more drops me stirring manually.
I am lost. Anyone offer any help? I know when I test alkalinity, I rub a wet paper towel with pool water in-between each drop to "prime" reagent. Could this be the issue? With me dropping it in so fast in the magnetic stirrer, I never release the chlorine reagent bottle, and thus dont introduce any air. I find that hard to believe though, because I did try the 20 drops, then transferred to magnetic, and still not clear.
Could it have something to do with the pill?
