I know there is a lot of threads on this already and I have read through alot of them. I apologize in advance for not taking the time to sort through them all. If someone wants to point me to the best ones or ones appropriate for my questions, I appreciate it. Or if someone wants to summarize and/or just answer, thank you too!

I have tested my well water and it has .2 ppm Iron and is clear. It just leaves a rust residue in our toilets/sinks/showers even after going through the water softener. I have only had 1 issue of staining in my pool and that is when I accidently let the hose rest on the step and that could have even been from the hose end itself. I usually will put hose in the skimmer basket to top off pool after evaporation/backwashing takes it down. I have used different filters in the past and the Hayward Bobby filter seems to work the best. It certainly works at the beginning because it will turn from white to rust brown/orange after a few uses. It says it will last for 20K gallons which is about 30 hours worth of running. After that it doesn't show any signs of not working, I think you just have to know its not doing much after that. I am not really sure how you know its time to replace??

If I dont use a filter and put the hose in the filter basket with filter sock on it the water will turn the sock orange after a couple of hours.

My questions are if I need to be concerned with .2 ppm of Iron? What filter(s) are the favorites of TFP? Do I need to be adding any chemicals when I top off with iron laden water?

I have a 25K gallon vinyl pool with SWG.
 
I'm on a well too and have plaster. Many have used the polyfill in a bucket rig to capture iron. Search polyfill on TFP.

I would be careful putting the hose in the skimmer basket to fill. Your SWG will be getting diluted salt water and may give you a low salt warning or stop working altogether.
