Hi James,
As you use the cones, the Current will progressively increase. Yes, generally speaking, after a cleaning, the Current will drop at least slightly, but over weeks/months, it will go from probably around I=6 to around I=10 or I=11.
With my Helios instruments, these are the signs I use to tell when to replace the skimmer-reducer:
1. if the Current goes up to 10-11 and stays there, even after a clean
2. if the oxide ratio drops below 1% and consistently stays there (days/weeks)
3. Tb and Tm values continue to decrease over days/weeks
If all 3 of the above criteria are met and it's been at least 5-6 months (fairly heavy usage), then I change the skimmer-reducer. Right now, under the fairly heavy usage of my 2 machines, we're getting about 6mo out of skimmer-reducers, so we have to budget for 2 per machine per year.
