    Free Chlorine testing loss of faith

    To report back, picked up 4 gallons of 4% bleach this morning and was consumed in no time, as it was way to expensive since that was all that was available today I did not buy any more, knowing I was out of bleach and at 0 FC left I had nothin to loose, so I set the SWG to shock (I know it...

    Free Chlorine testing loss of faith

    I am in montreal, canada and here it seems like all stores will be closed for easter, not trying to boost CYA as it is at 30 or so now, going higher will require more chlorine to keep at SLAM level and risk feeding CYA to the monster living in the pool at the moment. just got back from adding...

    Free Chlorine testing loss of faith

    Opened my pool last monday with lots of leaves in the bottom, scooped them out and got the pool going, color is good but water has been cloudy since than, I can barely see the bottom in the shallow end. I doubt it is algae as the water is at 54'F and none when I closed, most probably leftovers...

    Iron staining and 0 PPM when water tested.

    Out of curiosity I brought a water sample to the poor store to test for iron and the level is at 0, does this make sense? I would expect to see some indication of it in the water if it is all over the pool, if it possible it is not iron staining but something else?

    Iron staining and 0 PPM when water tested.

    My water is chrystal clear, so I will try that, add some AA to get it in solution and add some polyfill to the basket, and see if I can catch it. would my cartridge filter not catch some also? last time I rinsed it, it was white. Finally the main question does that Dazzle eliminator really...

    Iron staining and 0 PPM when water tested.

    Good Day everyone, Iron staining has showed up in my fiberglass pool in the last few weeks, confirmed with a vitamin C pill, rubbed on the stains and was erased, threw the pill in the bottom of the pool and made a nice long line where it moved due to the water flow. I have read up on AA...

    AQR100 Generating chlorine light

    Started up my pool this week, and noticed that if I put the setting of the Hayward AQR100 SWG to a low value the generating chlorine is on steady, if I bring up the setting to 4 or higher the LED will flash, the manual does not differentiate steady vs flashing generating chlorine LED light. Any...

    Risk of damage caused by freezing over the winter

    Inconsistent bleach quantity to FC increase in PoolMath

    thank-you MGTFP, it confirms my thoughts, up to now I would always use the estimate the effects to get the quantity of chemicals to add to the pool (MA, calcium chloride, stabilizer) now I know to use the 'log page'

    Inconsistent bleach quantity to FC increase in PoolMath

    replying to an old post but the original issue/question does not seem to be answered and I have the same issue, in the App, setting the SLAM button on sets my SLAM target FC to 14 from the actual 4.5 I have now. This suggests to add 233 oz of 2.88% bleach by volume to reach target (increase of...

    Brilliant Wonders 1.5 LED removal

    My Led light is now hanging in the bottom of the pool for the winter and found out that I don't have as much extra wire as I expected/hoped to keep the wire up and out of the water, I see that C-M-P has a cap that you can install, I have done all the stores in my area and no one is able to get...

    Brilliant Wonders 1.5 LED removal

    Thank-you For the answer, I do have a coil so lots of room to pull it out. What seals the water out? Is it really those O-rings as in the initial post? Which I don’t believe exist in a standard install, I would put money that the conduit is full of water I have attached pictures of the out side...

    Good Day all. My fiberglass pool has a Brilliant Wonders 1.5 LED light installed that I want to remove for the winter, it is at approximately 30 inches below the water level, so draining down to that level is far from being practical. So my main question is: is there an issue remove it under...

    Initial testing results and progress

    tonight PH is down to 7.5 but this gives me a CSI of -0.34 which is below the recommended values, -.42, as I asked in the first post should the CH be brought up? or just aerate more to raise the PH? to get a better CSI? being somewhat of a perfectionist, trying to find what ideal values across...

    Does anyone have the details for the settings on this unit, you have the choice, Smart Mode or Silent Mode, and unfortunately the manual does not describe the exact detail of what each setting does. Does anyone have this info?
