Filling a pool with water containing iron can be tricky, if you want to avoid stains.

You may want to order several quarts of polyquat, and a quart of HEDP. The polyquat will allow you to avoid algae, without precipitating iron, and the HEDP will help keep the iron IN the water (instead of ON the pool) till you can begin filtering.

Once the pool is full and the filter is operating normally, you'll want to lower pH levels gradually to around 7.0. Then you'll need to raise your total alkalinity to at least 80 ppm, by dosing with baking soda, 3 lbs at a time. The pH will rise; if it gets above 7.6, add acid to lower it to 7.2 before adding more baking soda. You can also add stabilizer during this time.

Once the TA is 80 - 100 ppm, with the pH around 7.4, you can begin gradually raising chlorine levels.

Tell us how you intend to chlorinate, and we can tell you how much stabilizer to add.
