Hi,
When I do a water change my ph is always around 8.4 and TA 220 with a Calcium Hardness of 220.
To bring my Ph and TA down I add dry acid then run pumps and air for 30-60mins and then test and repeat the process. On my recent refill I added the dry acid in the following quantities
200g , 120g, 70g, 50g, 25g untilI got the TA down to 50 with a ph of 7.5 which appears to give balanced conditions. The capacity of the hot tub is 1950 litres.
Could I have added more dry acid in one go to reduce the time to geat the water conditions correct or am I adding too much in one go. I have read somewhere that you should not add any more than 100g in one go.
Thanks
