    CYA notes and results

    oops, my bad on the math, maybe I need to do a few more maths papers :study: Yep open in October, close in March. Generally only get to swim Nov-Feb though, unless the weather is really kind like it was in 2015 (swam to early April then). But brought an electric heater this year so hoping to...

    Inconsistent TC results

    The other thing to note is are you testing for CC's. I might be wrong, because I dont have the OTO test, but I think this shows TC - total chlorine Whereas the FAS-DPD shows FC and CC, which you have to add to get TC I would be surprised if you have high CC's, but you may want to check this

    New Sand - brown/green water

The turning brown has me a little worried the wrong sand was used or something is wrong with the filter and the media is blowing back into the pool I agree with all the other comments btw, your decent test kit is needed asap to...

    CYA notes and results

    Just found the calculations for you. This is how you work out which bleach is the best value for money Price/ounces/concentration. $3.50 of 121 oz of 8.25% 3.5/121/0.0825=.325 or 32.5 cents per effective ounce $3.64 of 128 oz of 10% 3.64/128/0.10= 0.284 or 28.4 cents per effective ounce I...

    CYA notes and results

    I think you may be focusing on the wrong thing to try and save costs. Yes lower your pump runtime more. Try dropping it by an hour, wait a few days drop another hour etc etc. You will see when your water doesnt look filtered enough and then bump it up one more hour. Personally I run mine for...

    CYA notes and results

    Hi Jstblush Yes there is a correlation between ph and FC. The FC is more active at a lower ph (under 7.5), but this is somewhat mitigated by the CYA in the water. I believe at 30ppm CYA the active chlorine drops by 15% when the ph moves from 7.2 to 7.8. However even with that drop you if you...

    Combined chlorine high

    Hiya and welcome to the forum There was no need to lower the chlorine, it was not at a dangerous level when compared to your CYA See this chart which is on of the cornerstones of TFP http://www.troublefreepool.com/content/128-chlorine-cya-chart-slam-shock I would reccomend reading that page and...

    How to Take out the Filter

    What would be ideal would be a strap wrench. Seeing as I dont have one when I change my oil filter I use an old leather belt or strop strap. Just put the strap on and use the hanging end of the strap to pull in the opposite direction to twist it off Dunno why you are having trouble though...

    Add pattern to vinyl pool

    VHT say they make a vinyl dye for like vinyl car seat covers etc. Not sure if it is an actual dye or a paint type of product. I dont know how it would hold up under water with chlorine though. You would have to ring and find out if it would be suitable Have you ever looked at trying to...

    Just for fun

    Wow great posts I have always thought the 'çheck the date code' mantra a bit OTT As long as the bleach isnt stored out in the sun or heat it lasts for ages especially if it is lower strength Going by the odyssey chart 5% bleach has a half life of over three years at 75 degrees F
