Help - Green clear water

[masspool]

Just thought I'd leave an update. My pool has remained blue over the last three weeks. I did add sequestering agent once - one morning I detected the beginning of a greenish tint in the water (and added the sequestering stuff) and by the evening it was back to pure blue. I have not had to add any fill water, as we have had plenty of rain.

And, the CuLator doesn't appear to have changed color yet.

Thanks so much for the info. I'd really like to get a better understanding, this year, of how metals behave in pools, and responses like yours really help.

I wonder if you could do 3 things:

(1) Tell me how you've been testing. (Do you have a K2006, TFP100 or ?)
(2) Tell me what sequestering agent you used.
(3) Do white bucket tests on both the pool water and your fill water - to see if metals remain in either one.

First two are easy, of course. If you're willing to do bucket tests, here's how it goes:

1. Get a clean white 5 gallon bucket
2. Add 4 gallons of test water (do the pool first, fill water second)
3. Add 1/4 cup each of plain bleach and 1/8 cup of baking soda to the water, and mix till the soda is dissolved.
4. Cover and wait 2 days -- leave the bucket where it won't be moved or disturbed.
5. Check for sediment on the bottom, especially color.
6. Tell me what you find.

(1) I use the Taylor K-2006 test kit

(2) I use Clearview Mineral Magnet (by OREQ) sequestering agent.
(Note: At the beginning of the season (over the course of a week) I used three bottles of Natural Chemistry Metal Free and it did not get my pool to turn blue. I am not sure whether I had so much metal in my water, because I added so much fill water when I opened the pool, that it didn't reach the tipping point with the Natural Chemistry MF or whether the Natural Chemistry isn't effective. Anyway I switched to the Clearview Mineral Magnet and the pool turned blue in a couple of days.)


(3) Haven t had a chance to do the white bucket test


My pool has remained blue over the last six or seven weeks, but I haven't had to add any fill water (lots of rain)

My CuLator pack floated in the skimmer for about five weeks - and then sank to the bottom of the skimmer basket

And, the CuLator doesn't appear to have changed color yet.

Did it ever change color? We're not sure how well they work, but we are fairly sure they are a good presence/absence test for metals.

The CuLator bag has brownish-rust colored spots and streaks, but the whole bag has not changed color. The spotting is about the same color as my skimmer basket, which is probably ten years old.

Also the outer Culator bag has worn through (sort of torn), but there is a second layer-inner bag that is still intact.

If you are done with the CuLator, can you cut it open, and see if the plastic particles are discolored?



Here's what you are looking for

[masspool]

I just cut the CuLator open.....there are three clear marbles and some powder. The powder looks like the Low level Iron picture above in spots - combined with Nickel in areas

[PoolDoc]

pictures, can you take pictures??

(We're trying to get all the info we can on the product!)

I have a picture of the CuLator cut-open on top of a white paper towel


How do I upload it?
