rentit Posted February 15, 2009 Report Share Posted February 15, 2009 I've read a lot of the posts on the forum and have gathered several differing opinions on this. But, I've not found a post "dedicated" to this topic. For the experts on here, what is the best amount of time to leave the cover off after: 1) adding a "daily" amount of chlorine, say to 3-5 PPM 2) adding a shock amount of chlorine, say to 10-12PPM The goal is to balance extending cover life versus energy savings (losing heat). Finally, does a floating cover change your recommendation of length of times to leave the cover off? Quote Link to comment Share on other sites More sharing options...
Dr. Spa Posted February 15, 2009 Report Share Posted February 15, 2009 adding a "daily" amount of chlorine, say to 3-5 PPM = 0 adding a shock amount of chlorine, say to 10-12PPM = 15 - 20 minutes A floating blanket doesn't change this.

dm800 Posted February 18, 2009 Report Share Posted February 18, 2009 Does the same thing go for bromine shock? I have been using the Spaguard Enhanced Shock (probably not doing it as much as I should but plan to start doing it weekly), but I did it about 4 days ago and the bromine levels on the test strips are still off the chart. Do I need to be leaving the lid open when I add this? Generally, 2 of us use the hot tub once a week maybe, and it has not been used nor has the lid been open since I added that shock 4 days ago.
