    Moxie Oudoor Sodium Hypochlorite Percentage???

    Does anyone know the percentage of Sodium Hypochlorite in Mocie brand outdoor bleach sold at Lowe’s? I’ve searched MSDS sheets and am coming up blank. Figured someone here may know. I hate to experiment to see how much it raises my FC PPM however that’s my last option to figure it out “easily”.

    Chlorine gas released from hot tub water?

    Does anyone know how much chlorine is released from a hot tub as chlorine gas? Obviously, there are a number of variables here so we'll assume perfect water chemistry and FC level. Obviously, chlorine gas is 'suboptimal' for inhalation and I've always assumed (maybe incorrectly) that the level...

    Chlorine adding calc troubles with Taylor Test Kit K-2006

    Hey team! My pool's free chlorine level is 3.5 and I'd like it up to 5. Before I got rid of my $$$ pool company, they were adding on average 2 gallons weekly.

    Testing for Chlorine in the World of a Chlorine Shortage

    My friends at TFP are the best supporters of the FAS DPD test. Now, more than ever, people will want to know more precisely what their chlorine levels are. To me, FAS DPD beats color-matching, hands down. I do not do well reading pink colors. Besides making reading Free Chlorine more exact, FAS...

    In Dichlor-Bleach Hot Tub, are weekly chlorine shocks necessary?

    As part of weekly or monthly maintenance in a dichlor-then-bleach hot tub, are chlorine shocks necessary (12-13ppm FC, 30ppm CYA)? Or is it just in response to problems (cloudiness, odor, foaming, etc.)? Just getting over some hot tub rash, so I want to make sure I'm dotting every "i".

    Chlorine Bottle Exchange in Phoenix, Arizona

    Does anyone in the Phoenix, Arizona area have a place they recommend for chlorine bottle exchange? I currently recycle my 1 gallon containers, but at 3.5 gallons a week it still feels so wasteful. It’d be great to have a place to pop in and exchange.

    Contemplating getting a Pentair Intellichlor

    I'm wanting to have a better understanding of how SWGs work. My understanding is that they kind of work like a puck system (minus the increase in CYA and having to buy pucks - you buy salt instead). Is that close to accurate? Here is my current setup (see images) - I have a full Pentair system...
