Ok, did some simple tests last weekend with TF100 and took sample to pool store. Variable is a 20 minute ride to pool store with sample
There #'s with Lamotte tester
CC 0 a match
So why would I with drops be 3.9 ppm higher and ph .3 lower. I put a scoop of that powder in the vial at 10ml, could I be putting too much, are my drops to small(doubt it). My test with the Taylor FC/PH test was > 5 which leads me to believe my drop test is right. Can FC drop that much on a 20 minute ride in Air Conditioned Car? Store clerk saw me buying liquid shock (12%) and told me that I would raise PH by using that? I used to be in several times a week buying shock, now I have not shocked since going BBB, though I have not added Borax either, still uncomfortable with that. When I had a slight tinge of ping in my CC I spiked the chlorine overnight, not sure but I am adding about 20 oz a night and testing the next night and hold about the 5-6 range. Not sure what it is at in the am but I am guessing 6% takes me up 1 ppm.
Now for vacation, should I add 2-4 oz of PolyQ 60? I usually do 2 oz a week and have a neighbor watching the pool who also has pool.
