Can't figure out why my water is green

[Kcas0772]

I just finished the first 24 hours of the test. What should I be looking for exactly? The pool water bucket is same color as yesterday (clear) and clean. The are a handful of very very tiny "something's" in the water. Appear to be orange color but so small hard to tell. I assume this is probably just some junk that got drop in when I miss everything.

The water source bucket is also the same clear color and clean. Don't see anything in there really.

Sounds like precipitated iron, to me. If you think you might have dropped something in, redo the test to be sure.

If there is metal in the water as you suspect, what should I see after the first 25 hours? And tomorrow night after the next 24 hours?

It depends. If it's purely mineral iron, you'll drop whatever is there to the bottom within 24 hours. If it's bacterially chelated iron, say from nodular corrosion of iron pipes, it can take several days.

But if you have a potentially contaminated test, you need to start over.

Completed the 5 day bucket tests for the hose water and water in pool. There was no change to either bucket, so I'm not entirely sure what was going on. But I drained the pool and refilled it yesterday. Its clear this time, and the ph and chlorine are at good levels so far. Hopefully, it will just be fine going forward.

Iron contamination in city pools can be caused by INTERMITTENT problems, so it's entirely possible that you happened to fill at a bad moment, and resolved the problem by draining and refilling later.

The color of your tanks is positive indication that your tap water contains iron, at least occasionally.

Since you now have a fresh fill, our Super Simple Start-up Recipe would be appropriate for your pool. Info here:> http://pool9.net/ssr/
