Be careful using dry acid. It is sodium bisulfate and the sulfates will build up in your water and destroy your SWCG. Most SWCG manufacturers specifically state in their documentation to NOT use dry acid. Use muriatic acid instead. Keep lowering your pH to 7.6 when it gets to 8 and your TA will fall.

Bring your CYA up. Add about 40 ppm worth via the sock method. Once that is dissolved from the sock test for it 24 hours later. Then add enough to get you to 70 ppm CYA total.

Unless you have a huge amount left, go ahead and use up the dry acid. Just do not buy more.

Added muriatic acid 24 hours ago (31.43). Just got a lower ph of 8.0. Cya is 40. Fc 7, and y’all still 200

Getting better
Add a quart more acid now.
