    Converting from Chlorine to SWG - do I need to seal stone coping & waterfall first?

    I did not know this, thank you! I’ve been using 10.5% liquid sodium hypo from Pinch-a-Penny for the past year or so. Was planning on picking up around 12 40lb bags of salt to get it started, but now I’ll test first to see how much is already there. You just saved me from having to buy &...

    Converting from Chlorine to SWG - do I need to seal stone coping & waterfall first?

    I’m in the process of switching over from chlorine to a SWG. I’ve seen conflicting info about the need to seal stone before making this type of transition. I’ve got flagstone coping & a moss rock waterfall - is it recommended to treat these surfaces to prevent degradation from the salt, and if...

    You nailed it. FC is .8! Going to get an ammonia test kit right now so I can figure out how much chlorine I need to add to neutralize the ammonia. Once the FC loss begins to stabilize, then add the CYA, right?

    Just read through all of that. So I'm going to add 140 oz of chlorine to get me to a FC of 10ppm, then test again in 30 minutes. If it's down to 2ppm at that time, then I have an ammonia issue (even though my pH has been running higher & my CC has been <.5?). On the flipside, if the FC...

    I see what you're saying, I did not know that. The only new water added was 1.5" of rain back between July 7 - July 13. I have not checked for ammonia, in fact, you are the first person to suggest that something other than rain or splash out could result in a lowered CYA. How can I check for...

    How am I confusing myself? I used my own kit, the least it can show is 30ppm. After adding the four pounds my results were lower than they were before the addition. If anything I'm confused as to how this could possibly be. To backtrack, my CYA has been decreasing by large increments in the...

    It didn't look cloudy at all today. I tested on Friday (07/23) and it was a little cloudy, so I took a sample to the pool store for a more accurate number & they told me it was at 5. I am currently hanging my head in shame - I knew I needed to stay on top of it - testing & adding daily, but...

    I'm experiencing somewhat of a challenge here, and was hoping one of you experts can help me out. I did an ascorbic acid treatment a couple of weeks ago, and have been in the process of chlorinating to neutralize the AA. My problem is this - I added 4lbs of granular CYA on July 17 (half in a...

    Thank you for the response Maddie! Copied your answers below so I don't forget anything... 1) Have you drained water when your typical Houston rain has filled the pool?? If that rain water was mixing a while with the pool water, then you remove water you'll lose CYA. CYA only goes away to...

    Hello! I'm new to the group, so please correct & guide me if I forget to include any pertinent details. Here goes: We have an IG plaster pool, approximately 14K gallons - it came with the house, so there has been a lot of trial & error on our part to figure out the ins & outs of caring for it...
