Hello All, this is a great place, I wish I would have found it sooner.
We have had our IG fiberglass pool for approx 6 years and unfortunatly relied on Leslies Pools to test and tell us what to add.
Have been fighting an iron stain for 3+ years with advice from said store having dumped hundreds of dollars of their stain and scale remover in with little success.
Finally in desperation bought an ascorbic acid based granular stain remover called Stain Free. Lowered the Chlorine, dumped it in and our pool was sparkling clean and BLUE in literally 30 seconds. It looked brand NEW!
We were thrilled but you will notice I didn't mention a sequestrant so as soon as the chlorine started coming back up the metal deposits started turning the walls yellow/orange or whatever.
So.......We are trying to learn. We have a few issues besides the metals, High Alkalinity and High PH also.
Here are our numbers from yesterday with a TF100 test kit. How do we best approach getting our pool balanced?
PH:8.2 (or higher, max limit of tester)
Note: After testing we turned SWG % down and added 20 oz of Muriatic Acid
