Okay so I have the chemicals figured out but how long to wait between adding them is confusing me. I have a 4,000 gal. Above ground round intex pool. And I use the 4 step hth chemicals plus a clarifier when needed. What I am having trouble figuring out is how long to wait between adding chemicals. I have tested the water and added the ph reducer, is it okay that the chlorine tablet is floating in the pool during this step? Or all the steps? Since it is step 2, then how long do I wait to do steps 3 and then 4? Step 3 is the shock and 4 is the algaecide. All I can figure out is you wait 4-12 hours after those steps before you add the clarifier.
