Can't figure out why my water is green

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

[PoolDoc]

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?

[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.
