High FC and TC: Is this a problem?

[moyer02]

I have a new variable speed pump (which I love due to drastic improvement in electric bills) and I run it for ten hours at 1500rpm. I also have my SWG on for ten hours and it is set at 20%. I always have high FC (usually 10-15). All other tests are normal and my water is crystal clear. I can get the FC/TC down if I set my SWG to zero for a day or two. But should I care? Here are my numbers using the TF-100:

FC: 13
CC: 00
TC: 13

PH: 7.6
T/A: 110
CH: 200
CYA: 60
TEMP: 88
SAND FILTER PSI: 5

POOL LOAD LOW: usually me and the wifey

Can't you simply adjust the time on the SWG or the percent?

duraleigh, the IC-40 without an automation system can only be adjusted in steps of 20%.

You have a couple of choices. You can live with the somewhat too high FC level, you can get a Pentair branded automation system so you can adjust the percentage in 1% steps, you can shorten the pump run time, or you can get a separate timer and have it turn off the SWG for part of the time the pump is running.

I've seen that before and should have remembered

Guess I'll just set my timer to run the SWG for 8 hours instead of 10 and see what happens. I think I still need to run the pump for 10 hours since I run it at such a low rpm. Not wanting to invest in an automation system at this time...Thanks for all the comments.
