Can't maintain free chlorine

[Rickc1]

Thanks so much. I'll give it a try and see what happens.

So if I understand correctly. If I'm currently am at 2.5 FC and I get 2 1/2 gal jugs of 12.5% LC I would add 3 gals-one jug and about half of the second jug. Correct? Thanks again. Rick

on the shock chart it looks like shock level of 28 for a salt water system with my level of stabilizer. You note 20 in your response which is what I have it at right now. Is that ok? Thanks

What shock chart?
Adding amounts of chlorine according to your volume and current FC level is approximate. but you should add three gallons of 12.5%, not 2.5

I may be done. I will check in the morning to make sure haven't lost more than 1 in chlorine. Combined chlorine is 0. Thx

This is the link for the chart http://www.troublefreepool.com/conte...art-slam-shock. Last nigh FC was 20. This a.m. was 18 so guess not done. I just want to make sure I am getting FC to correct level (ie the 20 vs 28). Thx
