We have a reading of CYA 100 and on the chart I see I should maintain the FC level at 8-12ppm to allow for this. Is the water comfortable and safe to swim in with FC maintained at this level? I have let the FC drop to 5.2 but think I must add more to comply with the chart.
Our TA is very high at 220, we normally have low PH. My first reading with our new kit (LaMotte prof 7) had the pH off the bottom of the scale. I added about 25 kilos of PH+ and have now a reading of 7.4 which is OK. I have set the return to break the surface to try to lower the TA level. Is there anything else I should do?
