Can't figure out why my water is green

[Kcas0772]

Wow, thanks for such a detailed explanation. It may takes me until tomorrow to do the test, I will have to make a trip to the store this evening for some of the things I'll need.

Two questions in the meantime.
First, if it turns out that I do in fact have some metal in the water, but then we do the tap water test and that now comes back fine, is there a chemical that will fairly quickly clear this up, or is it better to drain and refill pool? Also, curious if any of the readings I listed in my first post from the pool store shed any light, like the copper/iron reading or the calcium?

Thanks,
Kevin

Using HEPD will not remove the metal from your water, but it *might* temporarily hide it. If you want to try it, this product is 20% HEDP: Do NOT overdose; if the right dose doesn't help, more won't make it better. Also, this product does ultimately add phosphates to your pool water, so you don't want to add more than is needed.

So i guess if it turns out the pool has metal in, but tested the tap water shows that the water is now clean, it'd probably be better to just drain and refill

If your water isn't too expensive, yes, a drain and refill would be by far the easiest solution.

If you like, you can run side-by-side metal bucket tests. Just be very careful -- white buckets, full fill, no contamination -- you'll be looking for very slight orange-brown bits of powder on the bottom.

I haven't done the test yet, bc I'm still waiting for the Borax to come from amazon which should be this evening. One more question, does it matter if I leave the buckets outside or in the house after it's prepared?

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.
