OOOOPS Too Much Potassium Permanganate

by John
(Oregon)

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:

CITRIC ACID

HYDROCHLORIC ACID

SULFURIC ACID

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.

To post a reply, or if you have a similar question, you can see your post (OOOOPS Too Much Potassium Permanganate) on the Q&A page in the "Chemical Questions" category.

Yellow Tinge And Not Too Clear Water
by: John

Ok thru diligence and a pool cover the chlorine good TA good pH good and I am backflushing and funk is coming out water still a little yellow.

Not too clear. I swept the wall, mucho cloudy now. Help more chlorine. Oh I did add etidronic acid 80ml.




Thanks for the follow up John

I still need your chemical readings. I'm sorry, but having a chlorine and pH reading of "good" doesn't help too much. Concerning the etidronic acid. I'm wondering if you're having an issue with staining or a high metal content with the pool water. Are you on city water or a well?

Etidronic acid is normally used as a stain inhibitor. This prevents the metals in the water from coming out of solution and staining the bottom and sides of a pool. It sounds like you're making progress and the pool is clearing a bit, but needs to be constantly filtered and back washed. A 1/3 - 1/2 water change might do well, but I still need your readings.

Thanks and hope to hear from you soon.
