For those who may need to know if Metal Magic will work below the recommended temp of 70 degrees, yes it will work with air temp of 58.
Sorry I don't have thermometer for pool. But, the water is really cold!
This is my idiot pool owner story of late
Temps here in NW GA have fluctuated a great deal with highs up to 70 a few days and lows to 40 at night. Lots of wind and rain recently.
We don't close pool for the winter, leave the pump on 24/7 and fight the leaves for a short period which we're in now.
Severe rain and wind a few days ago so I shut the pump off for a couple of days deciding to just let leaves sink and scoop out later.
Later came today because water getting cloudy and freeze warning tomorrow night.
I spent about an hour this morning scooping leaves and brushing the pool. Getting wet with cold water in high forty temps isn't fun but better than tomorrow when lower.
In my brilliant wisdom I decided to throw in not 1, but 3 jugs of 8.25% bleach to help with the cloudiness of the water that was present before my leaf removal.
I thought with some of the warmer temps and water not moving I might be getting an algae bloom.
It took less than 15 minutes for my cloudy blue pool to become emerald green.
Not until I came looking on the forum for solutions did I even remember that I have a SPECIAL NEEDS POOL!
I have had stain problems due to iron for a couple of years now but today, never once thought about sending my CL level too high and bringing the metal out with this addition.
I had been so careful all summer with my Ph and Cl levels. Careful to never go above Cl of 2.5.
Luckily after going to TFP (The Holy Grail of pool care) I realized I had done this to myself and figured out how to fix it.
Numbers weren't horrible.
Ph (7.5) - Cl (3.5) CC (0.5) I then looked up directions on Metal Magic (of which I had a several bottles) to sequester the iron.
By this time it was noon and temp was about 58 degrees. According to a post on the forum, ideal temp for Metal Magic needs to be 70 or above.
My chemistry would work okay but temp might not. I decided to try 2 bottles of the Metal Magic instead of the recommended 3 for my size pool just to see if it would make a difference.
I didn't want to waste the 3rd bottle if it wasn't going to work. Within 30 minutes the water was a nice aqua blue. After 2 hours it was a beautiful blue!
Still some cloudiness but no green whatsoever and absolutely no stain on my liner.
The amount of Bleach I added should have raised the Cl higher. About 8.5 if I remember correctly. That I don't understand. I tested twice to be sure. I didn't test CYA. Too little CYA could have contributed to quick loss of Cl but I wouldn't think over a 3-4 hour period. It was sunny today but definitely not hot. Who knows? I'm just thankful it has turned out for the good.
Hopefully my ignorance and resulting experience will help someone else.
Wishing you all a wonderful Holiday Season and a Trouble Free Pool!
