    SpeedStir Question

    Yes, you can use it for all mixing tests. I put the water in, then turn it on to put in the testing reagents. It is a wonderful tool!

    cya reagent numbers

    The letters after the R0013 are just sizes. You can use any of them. Here is a list: R-0013-A 0.75oz R-0013-C 2oz R-0013-E 16oz R-0013-F 32oz R-0013-G Gallon

    Can't Raise Chlorine Level After (2x) Stain Treatment

    I am doing the AA treatment right now as well. It will take some time to burn up the AA with chlorine. Give it some time. You will have to anyways because you don't want to shock right after doing an AA treatment.

    sand in water... your opinion please

    How often do you test your pool water? How do you test it? I got a hunch you may have algae clearing up and just happens you got the chemistry right just before you took your sample to the pool store.

    Newbie with some questions

    Appears you have algae according to your CC reading of 2.5. Raise your chlorine level to 26ppm and follow shocking directions in pool school.

    Heart rate monitor and swimming

    The problem is actually that the HRM shorts out in the salt environment due to the high conductivity of the water. The communication between the HRM and watch is possible since the transmission frequency of 5kHz is well within the range of radio wave transmission under saltwater. There are...

    Heart rate monitor and swimming

    This was posted on Amazon by a user that bought the same FT7 unit: "- Water Resistant. I have used this HRM in the pool and the monitoring is relatively accurate when it actually reads the transmitter. I believe the Polar website notes that in some highly chlorinated pools or seawater the...

    Will Phosphates increase chlorine demand?

    For the benefit of newbies, I have to say that believe what you like, but I would think that if you want to be well rounded in you line of business you would want to gain a COMPLETE understanding of what is going on. That way if confronted by any situation you would have the complete knowledge...

    Will Phosphates increase chlorine demand?

    Swimcmp, I am shocked that you have never seen a pool that cannot maintain chlorine without elevated phosphate levels with the 60-70 customers you say you have. I have one pool, mine, and it will drop to 0 chlorine if not monitored. I have always had low phosphate levels below 125ppb except...

    Will Phosphates increase chlorine demand?

    Well, I never did add the phosphate remover. The chlorine demand (or lack of chlorine production by the SWCG) seems to have gone down on it's own. So now I am thinking that the Poly is what was causing the issue all along. I also think that the loss of chlorine demand with the addition of...

    Will Phosphates increase chlorine demand?

    Jason, one thing to recall is that chlorine demand only went away when phosphate remover was used in the presence of poly. This means one of two things. Either the phosphates were the issue or the interaction with poly. Since I added phosphates, even though it was with metal sequestrant which...

    Will Phosphates increase chlorine demand?

    I tried to find out what exactly the Taylor K-1106 phosphate test is testing for but all it says is "phosphate". This is the test kit I am using. The previous time when the phosphate level was high, be it orthophosphate or some other variant the phosphate remover lowered the level as tested by...

    Will Phosphates increase chlorine demand?

    I never made an assertion. I simply asked a question based on initial observations to others that may have more knowledge than myself. After 3 pages of interaction with you and other members as well as some initial testing on my part it is apparent that phosphates alone do not have an...

    Will Phosphates increase chlorine demand?

    Chem geek, I don't appreciate how you approached your response. Apparently you think I am a chemist and have somehow disgraced the profession. I am not a chemist. I did not use the 0-20-0 to spite you, I simply wanted to recreate the previous results using the EXACT same chemicals I used...

    Will Phosphates increase chlorine demand?

    I can say with certainty that the combination of Suncoast All In One Algaecide and Suncoast Chemicals Salinity Stain Control has at least some effect on the SWG's ability to produce chlorine. I continue to lose 3 -4 ppm chlorine per day. My next step is to add the phosphate remover and see if...
