I read in some places you should see results in hours and in others days and even found one that said 1-4 weeks. I applied alum 24 hours ago and not really much in the way of results.

Thinking either A) my average depth calc was off or B) I need to wait a bit longer to see results.

Also my PH was 8 when I started and it only ever dropped to 6.5. I still added a bit of hydrated lime and brought it back to 7.5. Should I not have done that?

Thanks
