    Ascorbic Acid and Return of Brown Stains

    Hello swampwoman, I am the one who experimented with the Proteam metal magic last year. For the last several years I have opened my pool and after shocking, the stains formed on vinyl liner. I did raise the chlorine level when closing last fall but this year when opening, I did not need to...

    Me vs. Iron stains - Round 4

    I had similar problems last season. My CYA was up over 130 and I had metals which I could not figure out where they came from because I didn't have a problem until the last few years. One place many of us could possibly be getting it from is the concrete around the pool. Mine was reinforced with...

    Hi-jacked thread moved - bob22

    Re: Me vs. Iron stains - Round 4 I used 5 bottles of MM in my 27K gallon pool and the stains haven't reappeared. I also keep my ph around 7.5-7.6 It does say that MM will remove the metals from water if the correct procedure is followed. I still use the maintenance dose to be safe.

    Switching Sequestrate from EDTA to HEDP

    That's great to hear. I'm very happy with this procedure and would recommend it to anyone with a vinyl pool who first does the sponge test to see if the stains can be removed this way. Much easier than AA if it works, it did for me.

    Switching Sequestrate from EDTA to HEDP

    Thanks chem geek, I found out the hard way when I originally added metal free and polyquat together and the pool clouded for days until my filter cleared it up. swampwoman, You can start bringing up your chlorine level soon after stains are removed. For me I believe it was the second day and...

    Switching Sequestrate from EDTA to HEDP

    I would definitely do the sponge test to see if it removes the stains and how much metal magic is needed. You can find the sponge test directions on their web site. http://www.proteampoolcare.com/images/uploads/MetalMagicSpongeTest.pdf

    Sounds Good. I hope it works as well for you as it did on my particular type of stains.

    Switching Sequestrate from EDTA to HEDP

    I'm wondering if the sequestrate is masking the metals Wondering if A sequestrate will mask the metals in pool water when tested?

    Switching Sequestrate from EDTA to HEDP

    Good Luck Swampwoman, I am very happy the way my pool looks now. I can't get over the test results from two different stores and the cya readings compared to mine. I just finished bumping my DE filter again and it stays up about 1.5 lbs. higher than normal and That is only five days after...

    Switching Sequestrate from EDTA to HEDP

    My results from using Proteam Metal Magic to lift metal stains from my vinyl pool surface and then removing them from the water. I wanted to try Metal Magic because it claims to not only lift the metal stains from the surface but also remove the metals by filtering them out of the water. I have...

    Switching Sequestrate from EDTA to HEDP

    Swampwoman, I am in day two of the Metal Magic experiment now. So far I am pleased with the results. I can barely see any of the stains on my vinyl pool. During the day when the sun is out it looks like a new liner minus the fading. But when evening approaches I do notice a slight discoloration...

    Switching Sequestrate from EDTA to HEDP

    Will be doing it after the Memorial weekend because I don't want to fight cloudy water during this time. The stains are recent not old ones so maybe it will work. Worth a try at least. Thanks, Jim

    Switching Sequestrate from EDTA to HEDP

    Re: ProTeam Metal Magic Hi Jason, You stated that they are assuming somewhat different usage. They as in ProTeam claim the Metal Magic will remove the stains and also the metal from the pool water if used to their recommendations. No ascorbic acid treatment and ph 7.5 or preferably higher...

    Switching Sequestrate from EDTA to HEDP

    ProTeam Metal Magic I am about to start the ascorbic acid treatment and I'm a little confused with the amount of Metal Magic to add after the stains lift from the 27k gallon vinyl surface and why they want the ph at 7.5 or higher for best results. The bottle list directions as follows...

    Switching Sequestrate from EDTA to HEDP

    Hi All, I need to do the ascorbic acid treatment but I already added 2 bottles of EDTA Metal Free from Natural Chemist. I did this when opening the pool a few days ago. From this forum (Thank You) I would prefer to switch to the ProTeam Metal Magic HEDP sequestrate which I already ordered...

    New 2 Speed Pump Motor Installed

    Okay, It's cloudy out today so I shut my solar down to check power usage on my pump in both speeds and then without it running. Using the Calculator from here http://michaelbluejay.com/electricity/measure.html using Kh1.0 even though my meter says Kh7.2 here are the results. Hi Speed- 10...

    New 2 Speed Pump Motor Installed

    Thanks Jason, Well, it's a Hayward Perflex DE filter and I believe it has a swing type check valve. If I get a flow meter it would need to be able to be installed in a close proximity to 90 deg. elbows due to the short runs at the pump/filter. But those are expensive. I can't really use my...

    New 2 Speed Pump Motor Installed

    Hi All, I just installed a new (Century A.O. Smith B975) 2 speed motor on my 1hp Hayward Super pump (SP2607X10). Here are some readings I have taken to date. High speed- filter pressure- 8.5psi. Seems to run the same as the older single speed motor did. amps- 5.75 Didn't...

    Advice On Upgrading To A More Efficient Pool Pump.

    Thanks guys! I was a little worried there that I might have defeated my purpose of saving energy by using a higher rated motor but I see now that the pump design will only use a certain amount of HP. from the motor. Awesome!

    Advice On Upgrading To A More Efficient Pool Pump.

    The B975 might be an uprated 3/4 hp with a service factor of 1.4 which would make it a 1.05 hp motor. Is that correct? because the motor name plate doesn't have it listed as 1 hp but when I google B975 it comes up as a 1hp. and the guy advertised it as a 1hp. Hope that made sense!

    Advice On Upgrading To A More Efficient Pool Pump.

    I hope I didn't make a mistake and purchase the wrong motor. The one I bought 1 HP (B975) has a service factor of 1.4 and my old 1hp SF is 1.1 Can I still use this motor on my pump? SP-1607-Z1-M 1H.P. S.F. 1.1

    Advice On Upgrading To A More Efficient Pool Pump.

    Yeah I caught that. Good price for that motor (975T) but I do like the idea of the mechanical timer being less problematic. Just bought a new B975 on Ebay for $175. The build date was 2002 but that shouldn't matter because the motor data was the same as the newer ones. Now for a T106R...

    Advice On Upgrading To A More Efficient Pool Pump.

    I found a B975 1HP motor that has a U56J frame. Anyone know what the U stands for because my motor is just a 56J?

    Advice On Upgrading To A More Efficient Pool Pump.

    Thanks for your input Durk. I'll keep that in mind as I continue my research. I can do the wiring part so the new timer might be the better way to go and also solve the priming at startup on high speed. The way it looks to me is with the onboard timer the min high speed time is one hour and...

    Advice On Upgrading To A More Efficient Pool Pump.

    I also thought the payback on the vs might not be the best option. I see that they make a 2 speed replacement motor/with timer onboard for my pump. Now it's about getting the correct one and best price.

    Breakdown of bleach over time by storage temperature

    Thanks for the welcome! I've always closed my pool right after labor day using an all black bubble type cover beneath my mesh Loop Loc to keep the sun out. Next one will be solid with center drain! I'll add some chlorine before and after the freeze with very little problems when opening. The...
