OOOOPS Too Much Potassium Permanganate
SOMEHOW I WAS TREATING MY FILTER WITH POTASSIUM PERMANGANATE. I WASHED THE FILTER BUT A SUBSTANTIAL AMOUNT WENT INTO THE POOL AND NOW THE WATER IS YELLOW-MUD IN COLOR.
PH IS OK AND TOTAL ALKALINITY IS OK. I AM RUNNING FILTER 24/7 AND SHOCKING WITH STABILIZED BUT STILL UGLY KINDA DARK AND SCARY.. help???
Thanks for the question John
First, I'd like to have your complete chemicals readings: Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, Metals (iron and copper). It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store.
Without these numbers I'm just guessing at what the problem is. From my understanding potassium permanganate is an inorganic oxidant that kills germs and bacteria. As the quantity of potassium permanganate may not be very large, but is dependent on the capacity of the pool, it more than likely will not have any side effects.
The filter cleaner I've used for years is GLB Filter Fresh and others from GLB. The ingredients in the filter Fresh are:
You might be better served at looking to one of these cleaners for your filter. As for the water, you're doing right in filtering 24/7. Remember to back wash once per day as well. A 2nd choice could be to allow the Potassium Permanganate to fall to the bottom, then vacuum to WASTE.
