OK, so finally the pH is at 7.2
I will put in the 10ppm FC now.
Question: how long will it take for the CYA to register on a test? Richard320 mentioned that I could start the SLAM at the same time as adding the cya but surely I need to make sure that it's up to 30ppm? If I add 30ppm worth of cya and they have 20ppm already which isn't registering, then 12ppm FC won't be enough.
If we can't assume that the CYA is 0 then obviously I am going to add it a bit at a time. First lot will be 10ppm worth of it and see if it registers on the test, if not, then another 10ppm and if needed another 10ppm. That sound about right?
