+1 what mknauss said.
Then, after your test results, SLAM the pool..... algae came in with the creek water and the amount of chlorine you have added is not enough to clear and sanitize the pool
You didn't ask but I would be VERY cautious about filling from your well. Iron is common in well water and will plague you everyday of your life if you get enough of it in the pool.
Test both the creek and well water for iron content. I would rather see you use the creek water for refill than the well.
I assume you meant 0 ppm from the creek and .3 ppm from the well, is that correct?
I mistakenly suggested TFTest kits as a resource. They do not sell the test.
Test strips are completely worthless. A result of 0 is great but a result of .3 ppm is problematic. I will say again if you refill from an iron laden well, it will haunt you every swim season. If you refill from the creek (I don't know of surface water that contains iron) all you have to do is filter out the dirt.
Good question and the answer is, I don't know. If you refill about an inch, I think your existing chlorine could handle it. If you refill 6 inches, my bet is you would need to SLAM (not shock).So, let me ask this: when we do have to add water, is it likely we will have to shock again or is it possible that the creek water will be diluted enough to avoid that? What's your experience been with your pond?

I would consider rigging up some kind of pre-filter for your refill from the creek. Craigslist is a good resource for unwanted pool sand filters and that would go a LONG way towards introducing much cleaner water into your pool. dubuque general for sale - by owner - craigslist
No. I am pretty sure (now) I confused this thread with another thread that had really dirty, totally opaque brown water......sorry.So, we do run the water from the creek through the sand filter first and then through a duda. Do you think it needs more?

That said, were you still getting silt as you filled? My very big sand filter captured most of the debris and silt and you could probably see through the water a couple of feet when it went into the pool.
