    time for chlorine to diffuse

    Thank you everyone and Merry Christmas. Someone else mentioned that the chlorine would sink and I was wondering how it would ever diffuse. And, you are correct in that I have no pump. But, since the consensus is that the water must be “stirred” somehow I will consider the small pump and hose...

    time for chlorine to diffuse

    Hello, Organic chemistry wasn’t my strong suit. Does anyone know how long for liquid chlorine to diffuse equally throughout a 5000 gallon body of water if it’s poured into one area? When I service my bro-in-law’s exercise pool I just turn on the propeller for a couple of minutes. It’s great! Now...

    Cleaning the vinyl liner at the waterline

    Magic Eraser is working great for me. Scrub brush-not so good. Had to think of something because the rubber pool brush wasn't working and the dirt ring got pretty nasty over time. Gotta learn how to scrunch it up to prevent it from coming apart too soon. I got about 25' out of each eraser. Now...

    Chlorine level vs bather load

    Very interesting. We were using bromine but I never measured levels either during or after use. He itches occasionally after soaking and thinks it’s the bromine although literature states that bromine is less likely than chlorine to cause skin irritation. My wife thinks he just has dry skin...

    Chlorine level vs bather load

    Whoops, Just checked and I have 10%. But, the process will be similar. After I get things running I'll post results.

    Chlorine level vs bather load

    Thanks Jim, I use 6% liquid bleach for their exercise pool so I’d look up powdered chlorine and make the conversion. I do lots of testing for everything I’m involved in and figured I’d monitor things while people were in the spa and see for myself. It seems unanimous that some shock should be...

    Chlorine level vs bather load

    Hello, My brother in law wants to switch his spa’s sanitizer to chlorine from bromine. I read an older post which stated that the approximate bather load was 7ppm of chlorine/hour. If the level was kept at 3-5ppm this would seem to mean that you’d soon have no chlorine left in short order even...

    CYA-chlorine review

    Thanks everyone, especially to needsajet for giving a good explanation of how chlorine might affect vinyl liners. I was also wandering about a “rule of thumb” for the amount of chlorine that might be lost per day which was also mentioned in the replies. My losses are slightly lower but the pool...

    CYA-chlorine review

    Well, Since I have no practical experience or preconceptions, I have no fear of any chlorine level per se. But, as I learn how to take care of this machine, I’m trying to practice the “do no harm” portion of the Hippocratic Oath. Those who should know better than I express concern about elevated...

    CYA-chlorine review

    Yes, That’s the chart I’m referring to. I don’t trust industry boilerplate “standards” either which is why I continue to search out information.

    CYA-chlorine review

    Hello, I have been studying the CYA-chlorine relationship chart provided by Chem Geek et al. This is a well thought out analysis and the chemistry seems correct. But, no surprise, it brings into question recommended industry standards (at least in my case). We have a small (2400gal) outdoor...

    Can't stabilize Bromine bank

    Yes, I seem to recall mention of a speedster during my whirlwind tour of available testers. So, are we saying that a Taylor kit with a speedster is the good setup? I seem to recall a 2006 model number. Which would you recommend for my basic needs?

    Can't stabilize Bromine bank

    A Taylor test kit came with the exercise pool but was mostly empty. As I mentioned, I had trouble matching colors with the other kit they had so I got the Lamotte. But, I’ll probably get a Taylor just to have another comparison. Meantime, after adding another 4oz of shock yesterday morning Br...

    Can't stabilize Bromine bank

    Thanks for responding guys (girls as well?). The floater looks basic. I’ll look at the frog. Doing ½ the dosage is a good suggestion and I’ve started to implement it in the pool. Addition is better than subtraction. I don’t know how to check for combined chlorine/bromine (yet) but no chlorine...
