major or on stains on walls

Water Chemistry

We have iron in the water and have major stains. We tried metal free so no metal is in the water. We put 3 1.75lb bottles of stain free in a 40k gunite pool. Any ideas?

Hello Bubbah - We recommend using a Stain ID Kit. The kit comes with 3 different chemicals. One or a combo of a couple chemicals will remove your stains. You can order the correct amount of chemicals once the stain is confirmed.

I used 4 bottles of this. Seems to be the exact same instructions as Jack’s. This is what a pool guy said his wholesaler recommends.

It may take a combination of chemicals. That’s why we usually recommend the Stain ID Kit. It includes 3 chemcicals and detailed instructions on how to use a combo if necessary.
