I added 12.5% sodium hypo tonight to shock and I am trying to test the CL level RIGHT now. However, after I reach about 30 drops, the water turns clear, then if the water sits an extra 30 seconds, it turns pink again. Is this normal? Do I continue to add drops and count them towards the CL level? I don't know if I need to add more 12.5% tonight or not...something seems VERY odd!!
I was quite surprised that initially I got 37 drops after adding 240oz of 12.5% bleach!!! So I started over. Wondering if I will run out of R871 like many others on this board right now. CL was at 13ppm b/f adding the 12.5% and should have brought me close to 26 for shock level.
My water is clear and I have nothing on the floor or walls that could be eating away the CL levels that quickly!! I would have to have a swamp for that to occur.
FWIW....my CL level this am was 16, I had the SWG on for 1/2 the day at 100% and at 7:00pm the CL level was 13.5, so only a loss of 2.5 for the day even though the SWG was on 100%, but only 1/2 the day.
