    Buildup on SWG

    Thanks. After the muriatic acid, the PH was below 7 (the lowest my test will go), aerating some yesterday and all morning today has brought it up to 7.4. I don't really want to manipulate the PH at all, but the SWG scaling has been attributed to high TA around the cell; so in trying to deal...

    Buildup on SWG

    Well, I'm mostly frustrated from this weekend. While trying to bring down TA, I poured 3 gallons of muriatic acid into the pool, and got it to about 120. PH went down, and, I knew better, but the pool lady told me that PH Up wouldn't bring TA up all that much and to toss some in to bring PH...

    Buildup on SWG

    I called the SWG manufacturer, they did not include an O-Ring, which is probably causing my air bubble/leak. Seems solid now, but man, it's tight. Hoping the O-Ring will help this. I'll look into borates, and lowering my TA. Lower TA has been a goal, but I couldn't do much when I was...

    Buildup on SWG

    I just went out to look, and lo and behold, the air pocket was back. I cranked up the pump, it went away. I turned the pump off, then I found the problem. That little drip was enough for it to suck air back into the tube, creating the pocket. I tried flipping the cell around so the tab is...

    Buildup on SWG

    Hey all, good news, mostly. New cell and unit went in without much ado. A TINY drip coming from the housing, like a dropper per 10 minutes. not sure if I should be concerned, it's as tight as I can make it without using a tool. The first attempt I didn't have the notch lined up properly, so...

    Buildup on SWG

    I ordered a new "CMP PowerClean Salt Ultra 760 Chlorine Generator" for a 60,000 gallon pool. I probably should have done the 520 or whatever, but the 760 was what was already installed; so I just stuck with that. It should be here within the week, so I'm hoping for an easy switch out. Thanks...

    Buildup on SWG

    OK, I spoke with C-M-P. The service light comes on after a minute when on positive polarity, but never on negative polarity. He couldn't explain it, and recommended replacing the control unit, and said the cell was most likely fine. The cell will work with their newer systems, but may be...

    Buildup on SWG

    I found this video that showed holding the UP button until the polarity changes. In my original pic above, the polarity was negative. Ever since I cleaned the cell, it has been positive. I switched the polarity and the status light stayed off and it seems to be producing chlorine. I see...

    Buildup on SWG

    Good thought. The pump runs 24 hours a day on low, and the swg is always on. When we opened the pool this year, I set it on Boost and left it. I took the sample to the pool store and the FC was through the roof. They had to add a dechlorinator to the sample to bring it down to read other...

    Buildup on SWG

    I just happened to look under the box to see if I could get a model number. Says 2016.

    The wood stick was pretty black after hitting the faces of each cell. Did I remove some of the coating?

    Buildup on SWG

    I didn't use acid, the manual says not to, to only poke it with a wooden stick. The last salt reading was 5200. I'll have it retested, but the bottom of the SWG shows recommended 3000-5000 but 3000-32000 max. I went out to check on it a few minutes ago, sure enough no bubbles and the service...

    Buildup on SWG

    Well, I cleaned the cell according to the manual you linked above, and it was too easy. I reinstalled the cell in the same orientation as my picture above and cranked it up. After a few minutes, the air disappeared from the housing and all looked good. I looked at the panel, and the Service...

    Buildup on SWG

    HI Allen, thanks for the reply. The Alk levels are high I'm guessing because of all the chlorine shock I've been dumping in. The salt level was given to me by the pool store, when I took it in a few months ago. I have a Taylor 2006 test kit that did not have the salt components. We haven't...

    Buildup on SWG

    Thank you for the reply. For some reason I didn't get the notification. My last readings were: Pool Temp 83 FC 4.4 CC .4 PH 7.4 ALK 200 CYA 30 CH 90 Salt: 5200 (this may be bad). The pool calculator says to replace 100% of the water. That seems a bit overboard. Thanks, Sean

    Buildup on SWG

    I've been battling low FC all summer. I thought I had it under control, but again, the FC wont stay up FC info here . I keep adding liquid shock every other day even with the pool cover closed and no bather load. Still planning a SLAM in a few weeks once the weather gets to be where nobody...

    Can't keep chlorine levels up

    Hey all, thanks for all the help so far. Its been about 6 days since I added any shock, and slowly but surely my FC is creeping up with my SWG on 100%. Most of the other readings are about the same: FC 4.4 CC .4 PH 7.4 ALK 200 CYA 30 CH 90 The water is clear, but a slight haze at the deep...

    Can't keep chlorine levels up

    I didn't see your response in time. I left the SWG on all day/all night. I dumped in more 12.5 and read a FC of 12 and a CC of 1 yesterday evening. Cover was on all night, and around 11am I opened the cover and took another reading. FC 8.4, CC .4. A smaller drop in FC overnight. I'm not sure...

    Can't keep chlorine levels up

    Ok. Test kit came in, and I tested the chlorine a few times, other readings once: FC: 4.8 CC: (one reading was .4 and the other was .8) PH: 7 Alk: 200 Calcium: 90: CYA:30 The CC concerned me. Having friends over to the pool tomorrow, so I dumped a gallon of 12.5% shock in and running on high...

    Can't keep chlorine levels up

    Thanks for the quick responses. Do you think there is some algae still eating the FC in the pool? It has been covered most of the time, so UV should not be a factor in lost FC.

    Can't keep chlorine levels up

    Hi all, new here and looking for help beyond what my pool company can offer. I have a 16,500 gallon fiberglass pool with a SWG and cartridge filter. I'm fairly sure my SWG is working since when I had it closed for a week or two at BOOST levels (forgot all about it), the levels were off the...
