于 2009-05-16 10:19 The O3 takes 3-4 days to increase the ORP reading from 280 to 450. When I have turned it off, It drops back to 280 within a day. It tells me that my ORP level is 280 (satisfactory level) without the assistance of O3 machine.
Findings:
The reading was 180 in my first use. (before the purchase of O3 machine). i.e. There's a improvement of 100 without further use of O3 machine.
Question:
How can I further improve the ORP level to higher range without the deployment of O3 machine. e.g. 450. Should I add some live rocks or live rings to increase the capacity or continue to operate the O3 machine until the stable level has been reached so I can turn off the O3 machine then?
