Newbie - Stain removal via ascorbic acid

[aylad]

Store bought "bottled water" was tested for copper and produced no reading.

Ben, unless I misunderstand what you were getting at, I'm not sure that you've established that his tap water is copper-free.

My bad -- he proved that the store was distinguishing copper free water from water with copper. I'll re-edit to correct.

Thanks,

I have been using the same pool store for our readings. I just ordered a Taylor K-2006 test kit so I can begin to rule out errors in the testing.

Backwash early this morning was very green, like I've never seen before. Most of the green is now off the walls and were left with light staining in the shallow end bottom and the water is very cloudy / milky water.

Since I have well water, I have the water tested frequently by a professional lab. Last testing was done 4 weeks ago, No Copper. Prior to this year we have always had the water running thru a heater, so any previous years reading of copper were attributed to that, the heater was disconnected in early June.

At this point I want to get clear and balanced,,,let the staining fall where it may, and I'll basically start over again once I'm in a clean usable state,,,or next spring (which ever comes first)

Sorry, I really don't have my mind on this. I'm in the middle of three different projects, and flipping between each one. That's not the best way for me to work.

I'd forgotten that you'd been using copper / trichlor tablets; I just saw that again. I assume you've discarded them? (Actually, if you haven't, then put them in the garbage, in a plastic bag, 1 or 2 at a time. Trichlor does't mix well with garbage, and if you put a bunch in at once, bad stuff can happen.)

Also, if you've mentioned before that you've got well water, I'd overlooked that, too.

If you are ready to pack it in for this year, just raise your chlorine and hold it above 5 ppm till you clear up. At CYA = 30, that should do it. You might hold it at 10 ppm, till you get the 'green' gone.

Meanwhile, DO have your well water tested. It's common to have metals in well water, and if you do, you need to know. It's a pain either way, but it's less of a pain if you deal with the metals from the start, instead of after the fact.

Sorry for the confusion. Unfortunately, dealing with metals is rarely straightforward in my experience. Over time, I've always been able to work out a way to deal with metals in each particular pool, but I rarely worked it out on the first pass.
