    Why would Trichlor SLAM work and Sodium Hypo fail?

    Firstly, thank you to both of you for your replies. Early in the season options were a little sparse and I did open the pool about 2 weeks later than ideal, but that can happen anyway. I would agree. To be clear it was at about 20 before treatments, I have since raised it to around 40 (for...

    Why would Trichlor SLAM work and Sodium Hypo fail?

    Last couple of years I have been SLAMing with 9.6% hypochlorite and had no issues. Last year no matter how much I tried I could not get the pool to hold chlorine and was using 3-5 times more dichlor than a usual year. I had intended this year to drain and restart but in the end decided to give...

    Mustard Shock and test strips

    Thanks for a more complete response, I hear what you are saying and I know (from past experience) that your first reply covered 90% of new maintainers problems with pool opening. About 6-7 years ago I had a problem with excess CYA and had to do a drain, since then I have avoided shocking with...

    Mustard Shock and test strips

    As I said above, I can’t use these types of kits due to a disability. Frankly the test strips are tough enough.

    Mustard Shock and test strips

    I should also mention that I avoid test kits like the Taylors etc. due to a disability that makes them tough to handle.

    Mustard Shock and test strips

    With respect I am not ‘dump and pray’ type, pool calculator said 7litres to shock under the conditions I had. Been trying to maintain it for 24 hours but with no luck at all. Yes strips aren’t especially accurate but they are easy and haven’t let me down in 15 years until now. Logically if the...

    Mustard Shock and test strips

    Opened my pool late this year and was lucky that it hadn’t bloomed. Whilst trying to shock it with 7litres of 9.6% bleach I found my Aquachek strips showed 5ppm total and 0ppm free chlorine. So I have added what should have been enough to mustard shock my 48 cubic meter pool. Still my test...

    Total Chlorine less than Free Chlorine ???

    frogabog, If you wanted to double the range of your tester you could :- 1. Take water sample and mix it with distilled water 50/50 (a plastic syringe from your local pharmacy would do this accurately) 2. Perform the test 3. Double the result You could also triple or quadruple with the same...

    Total Chlorine less than Free Chlorine ???

    I am convinced that the TC test was done too fast , the other tests concurring with my own. If I could get one , I would by a TF100 kit but they wont ship to the EU. Then I would have a full set of tests of my own. Discarding the TC result in the first post , would you all be happy with the...

    Aeration with SWG ?

    OK , at the moment my TA is between 40 and 90 (depending or whether you trust my test TA of 43 or the store one of 90). From the SWG balance pages here I should (taking the average of 65) be within tolerance. I will leave the aeration off. Thank you for the reply and info Jason

    Total Chlorine less than Free Chlorine ???

    Totally agree with what has been said :) The mere idea of TC being less than FC concerned me but, with my lack of experience I had to check that such a result wasn't a sign of something other than a testing error. I also agree with the norm being a lack of user ability in some stores and so...

    Total Chlorine less than Free Chlorine ???

    Thanks for the reply frogabog, The results mostly match the tests I have at home (pH meter , Aquachek Yellow strips and Aquachek TruTest digital) in as far I they will test (only get FC and no CH with them). The shop tests were all individual tests samples and the only thing that concerned me...

    Aeration with SWG ?

    Hello All, I have a pool with a SWG and fairly well balanced water , The return eyes have air venturi ports on them that when opened add bubbles to the returned water (not a lot but clearly visible). I assume the would be deemed a aeration but, is it of any value to my pool to a)keep them...

    Total Chlorine less than Free Chlorine ???

    Hello All, Yesterday I replaced my SWG and whilst I was at the shop I had my water tested. They used a automated precision pipette to measure water into individual test 'cells' that were pre-dosed with the testing chemical and sealed (obviously this seal was broken to add my pool water). Each...
