    Purchase chemicals

    I've not taken my pool water to be tested at a pool store for many years. I use the T-100 kit, and have been met with excellent results. When I do need to buy chemicals, I look on line and come across a gahzillion sites, all having a variety of brand names. Anyone know of a any sites that are...

    Stains-what to do?

    In the end: SGM did provide for my pool to be resurfaced, at no cost to me. But dealing with SGM was a nightmare. They did not respond to any of my forms of communication. I used the services of the BBB, of which SGM is not a member, but it did get their attention. Finally file a complaint with...

    So do you think his proposal about acid washing without emptying the pool has any merit?

    Stains-what to do?

    The latest in the ongoing saga saw the installer & a tech rep from SGM here, at the same time, looking at my pool. To their comments & questions about managing my pool water chemistry, to the quality of tap water in this region, I responded with the information all of you have so kindly...

    Stains-what to do?

    onBalance: Thanks for your response. Short of draining pool & etching (which I wish to avoid), is there anything that can be done to eliminate the mottling?

    Stains-what to do?

    Can't thank you all enough! Once the FC levels come down a bit, will do the stain ID kit, and go from there. When the tech from SGM looked at the pool, he, of course, said the Diamond Brite "did not fail", and the discoloration was, in fact, mottling. This mottling occurs randomly & only on the...

    Swampwoman & pabeader: Again, thanks for your comments. Just got off the phone with the tech at Jack's Magic. He confirmed that salt is actually part of the TDS level, so subtracting the salt level from the TDS level will provide a more accurate reading of TDS, so using their Stain ID Kit is OK...

    Stains-what to do?

    Many thanks to all of you for you suggestions. You've gone above & beyond, and it is very much appreciated. Attempted to attach photos. Couldn't get my shadow out of the way. The Diamond Brite color is "Cool Blue". Hope the blotchiness of the discolorization is clear. It appears throughout the...

    Stains-what to do?

    pabeader: I turned the SWG off 7 days ago, hoping this will contribute to lowering the FC. If I read the information from Pool School correctly, all the other chemical levels seem to be within range. Does that seem correct? Also, I tried the a vitamin C tablets/chlorine tablet procedure you...

    Stains-what to do?

    TF Test Kit finally arrived! Followed all directions to the hilt. Did tests twice, on two separate days. The results: Calcium Hardness: 375 TA: 90 CYA: 60 I saved Chlorine for last because it seems to be an issue. I think the ppm is off the charts. In both tests, after I added the R-0870...

    Stains-what to do?

    Many thanks! Didn't know it could be that simple. I shall give this a go. Have ordered the T-100 test kit. In the meantime, had the pool water analyzed at local pool store just to get some "ball park" figures for starters. Would be interested to learn what you all think these figures might...

    Stains-what to do?

    Diamond Brite was applied to our pool in early June, 2015. We added Hayward AquaBrite t-15 salt chlorination system in mid September. Since that time, we've had difficulty keeping the water balanced. I take a sample to our local pool store once a week, and have always needed to add something...
