    1yr old fiberglass pool - white staining under waterline with balanced pool. calcium?

    I've fought this issue like Texas since 2016. Pool installation in 2015. I even went with Ecofinish as a remedy. I still get chalking/fading. I still bounce between fading/chalking due to UV exposure or chlorine even though I'm rarely above 5 or 6 ppm FC. I shock with no chlorine shock and...

    Calcium scale and negative CSI in fiberglass pools

    Seuss, how are things looking? I have the chalky stuff again. Has to be something in this Cape Fear water or maybe salt residue? Is salt staining possible? Chlorine has been hovering around 1ppm all winter. Calcium is around 100ppm. I adjusted Ta and pH and shocked with non chlorine oxidizer in...

    I agree on color. I am definitely having same issues again albiet not as bad as in past YET and it's not calcium or high chlorine in my opinion. I checked and I'm at 4ppm FC and calcium is probably below 180 by now. Have inline chlorinator off but still getting some chlorine in pool. My thoughts...

    Thank you for replying. First thing we get told by suppliers and contractors is it's us, chemistry and maintenance which I understand there are a lot of variables and mistakes made but for those that try to be diligent and keep your investment nice it's very frustrating to look at. Just in...

    Calcium scale and negative CSI in fiberglass pools

    Seuss, How's the pool holding up? Mine is showing the oxidized effect again. Chlorine levels and calcium isn't my issue because they have stayed low and even lower as it cools off. Running SWG at 10% and staying around 3-4ppm. CSI is negative and has been slightly negative as I have been...

    Calcium scale and negative CSI in fiberglass pools

    Yeah that is completely different than what he told me or even his placard reads. He told me several times Trichloro-S-Triazinetrione was fine to run in inline chlorinator. I just recently put calcium in the pool. Like someone told me once we are balancing the water not the surface. I may not...

    Seuss, where do you run your swg? 60% pushed me high and now I've backed off to try to get it to drift into range. Where do you run at daily?

    Calcium scale and negative CSI in fiberglass pools

    Just posting this as I keep up with surface to show water is dialed in for most part. Still not 100% perfect by TFP levels but in the acceptable ranges. I rarely shock like Tex says. I just do it in ou-oh instances when its fairly low. When I do shock I use the OXI stuff. Not using any clarifier...

    Calcium scale and negative CSI in fiberglass pools

    Seuss, After storm last night I drained some water off. Kicked on SWG, added some ph down to nudge it down, added some CH to bring it up, Below are my numbers. I am still bringing things into TFP recs but have a -csi and to my understanding should have any chalking/fading issues. I do see see...

    Calcium scale and negative CSI in fiberglass pools

    After posting I took a magic eraser and swiped an area I noticed slight chalking, fading, oxidizing, staining or whatever we want to call it and blue came off. I do notice some traces of blue on vacuum tracks. I back washed and noticed a faint blue in water from sand filter during backwash. So...

    Calcium scale and negative CSI in fiberglass pools

    Thank you for the links. I don't have much CC to speak of when testing. "You must be passing multiple OCLT's and have no CC." What is the OCLT abbreviation? I really am thinking about putting salt back in and go back on SWG. I like the feel. Last year I was dialed in to TFP numbers and still...

    Calcium scale and negative CSI in fiberglass pools

    I suspect both of those are a waste of time and can be eliminated? seems like I remember reading such. Does the clarifier not help group particles to catch in filter or no? I'm surely glad to not use them if staying balanced is sufficient.

    What potions I'm I using? Where do you see the problem? I really am on the minimalist side about adding anything not needed.

    Calcium scale and negative CSI in fiberglass pools

    A couple pics from April and May. I will try to get something today for a comparison. I will add that EcoFinish isn't as shiny and deep pacific blue as the original gelcoat but I knew that. I also knew it would have a feel of a tangerine type surface. The original was almost the color of a...

    Calcium scale and negative CSI in fiberglass pools

    Hi Suess, I didn't get any word about don't use chlorine. I talked to Tony this week to ensure I was doing what is suggested. I was told to stay away from cal-hypo specifically and definitely not toss shock or floating feeders with it in and let it set on surface. I have trichloro tablets in...

    Calcium scale and negative CSI in fiberglass pools

    So far this year all I have done since it was a new fill back in Oct/Nov is I dialed in TA, now pH is bout 7.8 and shocked about three different times using that potassium monopersulfate shock. FC is is about 2.6 right now and using trichloro tablets in chlorintor. I ran my tests for CYA and CH...

    Calcium scale and negative CSI in fiberglass pools

    Hi! Doing good and glad you are. So far so good on pool. I'm using only non chlorine shock potassium monopersulfate and using trichloro-s-triazinetrione tablets in chlorinator. Been keeping FC levels between 1-3 ppm so far. Actually, I followed the ecofinish levels they gave me. Evidently, using...

    Best practice closing a Fiberglass EcoFinish pool?

    Hi All, This year due to industry gelcoat issues with my fiberglass pool I had EcoFinish sprayed in as a solution. I just recently had another layer sprayed in due to some fading/chalking issues that may have been caused by my chlorine habits. Mainly running higher chlorine than the recommended...

    Suess, Ecofinish guys came out today. Looked at surface and tried some things. They ended up draining the pool and first just heated the surface to see how it would react. It helped but didn't eliminate the fade residue look. Next they pressure washed it and sprayed another coat In. Looks good...

    Calcium scale and negative CSI in fiberglass pools

    Will do. I will call EcoFinish this week and get the ball rolling and update you on what I hear. I figured phosphates wasn't issue but figured I would mention it. Not much I can do about phosphates since I am getting them from tap water. I've had no issues with SWG lately. On this residue I'm...

    Calcium scale and negative CSI in fiberglass pools

    Hi drsuess, Did you call EcoFinish? I was thinking about doing so today. To cover my bases I decided to get a Jack's Magic Stain Id Kit to make sure I wasn't having any staining from copper, calcium or iron. Tests made no difference as I thought. I really feel its the same issue we were having...
