    Ascorbic acid treatment and Sequestraint.

    I am hoping this is my last post on this particular adventure.

    Ascorbic acid treatment and Sequestraint.

    I have been going through the process to remove some iron stains in my liner pool since opening. So far everything has worked great! After letting the AA recirculate without filter, a bunch of dirty sandy powder appeared all over the bottom of the pool. Anyone know what this is? Could it be...

    Keeping stains away

    Not 100% sure since we have always used municipal water and didn’t have a problem before. I now have a hose filter on before the pool to ensure the iron is removed so I have metal free fill water. So I guess I keep sequestering until I have replaced enough water to reduce the iron.

    Keeping stains away

    So I have been going down the rabbit hole to remove and keep away the iron stains. So many questions and clarifications I want details on but for now let’s stick to this one thing at a time. I have treated my pool with ascorbic acid and it lifted the iron stains. Now all the Fe3+ is soluble...

    What is the best sequesterant to use after AA treatment?

    We closed our pool last year with some iron stains on the vinyl liner surfaces. We identified the stains as iron by using Vitamin C tablets. It was too late in the season to bring the pool to 0 FC and then wait to SLAM for closing. So we closed the pool and just opened it back up. After doing a...

    Any experience with the AccuBlu or LaMotte Spintouch test setups?

    I am a chemist and have been able to get my hands on one of these if I wanted. I know a lot of pool stores use one of these 2 or something similar, while I don't trust pool stores themselves the tech seems to make sense. It would seem to be a spectrometer that reads in the visible light range to...

    Openning with metal stains

    I guess my question was more on keeping the FC levels up if I am losing water, as I vacuum to waste, and adding fresh from the hose to refill. IF it isn't thick do you not do the vacuum to waste and just SLAM until the algae dies and then have the filter take it up.

    Openning with metal stains

    Thanks. When we have so much algae how do you maintain SLAM while vacuuming to waste?

    Openning with metal stains

    Last season I had awful stains on the liner that at first I thought were worn spots on the liner, but it turns out they are metal stains. I tried to remove it with vitamin C and it came up. However, they are throughout the pool and a simple vitamin C tablet in a sock didn't fix the whole problem...

    Pentair Superflo VST (VSP)

    So apparently the displayed speed on the pump we have (Pentair Superflow VST) is in RPMs how do I convert that to GPM so that I know how often my pool is being turned over? The pool company installed it and set up the VSP scheduled timing. I don't like to just trust others with my pool, I want...
