This is our first year with a pool.

We have the intex 18x48 ultra frame. Filled it with our (rusty) well water. Everyone around us said to just keep filtering it and use shock and it will eventually clear up. Started filling Tuesday, finished Wednesday, and today (Saturday) it's the worst it has looked. It's been brown and turned greenish yesterday. My pH and chlorine levels are in normal ranges using the HTH drop test kit. Used the HTH green to blue last night at a friend high recommendation and now there is a darker brown with an orange-rusty film along the entire top of the pool.

I'm freaking frustrated and no idea what to do. Ready to throw in the towel!

Help please!
