rsc92 Posted November 9, 2010 Report Share Posted November 9, 2010 My ACE System has been up and running for about a week. I have a Vanguard, Set Spa Size to 6 and Usage to 4. One or two people use the spa daily for 20 minutes. The ozonator is functioning as well. My FC level has been ranging between 0 and .5. Do I need to add dichlor to give it a boost? The water is crystal clear. Suggestions? A tub with a non-stabilized .5ppm reading for FC is actually much higher than a tub that is CYA stabilized and has an FC reading of the same value. I think that a .5 non-stabilized reading falls pretty close to the target range of 3-5ppm for a stabilized tub. However, I have seen more consistency and less fluctuation using dichlor to maintain at least some CYA reserve. After adding dichlor slowly to get a reserve (my Grandee likes the 10-15ppm CYA reserve range), your FC should climb up into the 3-5ppm range and stay there. Congrats on the Vanguard BTW! How are you enjoying it? Thanks. The Vanguard is great. Quote Link to comment Share on other sites More sharing options...
