If you only have a few weeks to go. Just use the Cha Ching. Shot rocks on its own the last few weeks. If your tap water is 7.7 then I bet your ppm are pretty high also. So the lime may be adding insult to injury.
Would you flush with Clearex now too? Then Cha Ching it for the last few weeks. My runoff has been in the mid 5's so maybe I should get some PH up from the hydro shop instead of using hydrated lime.
