    Using Caustic Soda to neutralize Cyanuric Acid

    Thanks for your kind comments. The youthful laughter is bound to continue for many years to come as we had a small "accident" during one of the national Covid lockdowns where we stayed 8 months in the cabin. There is after all a limit to how much Netflix a guy can watch.

    Using Caustic Soda to neutralize Cyanuric Acid

    I have monitored FC for the past 7 days and it is dropping 3 ppm/day. This is equivalent to 600 ml of 6% bleach, so I have installed a dosing pump to add 300 ml twice a day, 6 am/pm. I have a 12 gal reservoir, so that should last for just over 2 months usage. I guess the next thing to watch out...

    Using Caustic Soda to neutralize Cyanuric Acid

    The penny finally dropped for me as how to understand the CYA/chlorine equilibrium. Thanks guys. I did a 1:4 diluted test, which came out at 75 ppm cyanuric acid, so I am stuck with 300 ppm. Adding 3 litre of 6% bleach will give me +15 ppm FC or a total of 29 ppm FC. I will try to maintain FC at...

    Using Caustic Soda to neutralize Cyanuric Acid

    I am back on the island and have activated the K-2006 test kit. First off, I had to add 1,200 g (42 ounce) of caustic soda to get the pH back up to 7.2. My cyanuric acid level is approaching scary numbers around 250-300 ppm, but I am desperate short on water in the neutrino detector, so I can't...

    Using Caustic Soda to neutralize Cyanuric Acid

    Yep, but they are slipping through my filters. I am capturing rain from the back, front and part of the balcony roof. We get about 80" of rain here annually, with about half of that during a very intense monsoon season.

    Using Caustic Soda to neutralize Cyanuric Acid

    We are about to return to the house and I will start to install and test the bleach dosing pump, but since I am still short on rain water let me share a picture of my 10,000 gal holding tank.
