I am a new pool owner and my pool is about 2 months old. I have learned to balance my pool in regards to chlorine, pH and alkalinity. The other day, I noticed a brown stain around the circumference of the pipe that returns filtered water into the pool. I asked my pool builder and he told me it is due to the metals in the water.
Can anyone tell me what kind of product would be best to remove the stain? I was told to use Jacks Magic but there are many different kinds. I was told this will remove the metals from the water.
I was told to use Stain Free Plus to remove the stain itself. I could not find this product at my local pool store. Any idea for another product to remove the stain?
