What to test every week (and what you only need to check monthly)
The seesaw trick for fixing high alkalinity and low pH at the same time
The exact order to add chemicals (it's alkalinity first, then pH, then chlorine, then CYA, then calcium hardness)
How much to add with real dosing examples for common pool sizes
When and how to use shock (both chlorine and non-chlorine shock) and why it matters
Once you know the order, the whole thing gets a lot easier.
Happy Swimming! 😁
