Hi just did a slam ( see previous thread "Slam now or wait"
started 7 days ago , in summary had a CYA 60 and slammed at FC 24. Passed A no CC, B OCLT loss <1ppm and water clear so Tuesday 10nov waited for FC to drift down to target 4. Wednesday 11Nov FC 21.5 OK, Thurdays 12Nov FC 18 OK, Friday I was away, Today Saturday 13 NOVEMBER FC 16 but when brush wall getting green. Water looks clear.
i have filtered for 8-10 hours per day, brushed everyday except Friday and vacuumed every second day.
What did I do Wrong?
I'm still waiting for my K-2006 kit so cannot give you other tests with certainty. My other kit has pH 7.5 & TA 60.
