    fc is steady at 2ppm

    I have a salt water gen. and fc is steady a 2ppm and cc is .5ppm. Is this too low. salt water gen is at 100 % and I run filter 12 hrs a day.

    Not sure right now of cya because I just put in 4 lbs a few days ago. It was about 45 last reading.

    Not high enough. You need to plug your numbers into the pool calculator to see where you need to be w/a cya of 45. Check your cya levels again a week after you dosed it because it doesn't always show right away.

    Also.. w/CC of .5, I would recommend staying on the higher side of your chlorine recommendations to keep any algae from getting hold... just my 2 cents.

    WIth CYA at 45 and a SWG, and FC level is 2 is just enough. But that doesn't leave you with any margin in case of problems.

    If you raise your CYA level to between 70 and 80 the SWG will have a much easier time keeping up. Your recent addition should bring you to somewhere around 70, so presumably things will start improving soon.

    thanks. lots of rain past few days so I think I may need to add more cya soon but will check first.
