Hi,
I have a simple vinyl pool in my garden. It is an oval type, holding 30.000 liters or 8000 gallons of water. I'm regularly measuring the chlorine/pH values, and keeping it on ~1mg/L and 7.2. Unfortunately we don't have here (Hungary, Europe) very good test kits like the Taylor K-2005, just the Taylor K-1000, plus I bought the R0003 reagent to be able to measure the combined chlorine. So unfortunately I don't have data like TA or CYA.
The latter is surely in the water (maybe way too much), because the pool is treated with chlorine tablets, and it is shocked with dichlor granulate (I know it is not the best idea).
Yesterday I measured a 0.5mg/L of combined chlorine so I decided to raise the chlorine level. I added ~400mg of dichlor (56% chlorine content), which is equivalent of ~7mg/L FC in my pool. I know the well known breakpoint curve of ammonia/combined chlorine.
After adding the chlorine, the pump was on for several hours. I made 4 measurements altogether, with the following results:
- before treatment: 0.5FC, 0.5CC
- 1 hour after treatment: 2.5FC, ~4CC (went up pretty much)
- 10 hours after the treatment (following morning): 0.5FC, 0.5CC
- 24 hours after the treatment (now): 0.5FC, 0.5CC
the solar cover was not on the pool during this period.
I am not sure where I am now, because practically the results showing the same concentrations as before.
Did I reach the phase II on this curve, or where am I?

Should I add chlorine again? I'm a bit confused seeing these values.
One more: the water looked very clear before, now it is crystal clear, so no problem with that.
Thanks in advance!
