Good idea to do both. Do NOT buy anything from them. Let us know what they suggest if anything. If you feel the urge to buy something get a cute float or pool toy.

Good morning, Ohana. The "stain" threshold is usually 3-5 times higher than your readings (eg .3-.5 ppm.)
Its a personal choice but with .1 levels of iron and copper I would personally not take any action. I would wait and see whether or not it builds up over the season and whether or not you get any faint/mild staining. Rain may dilute the level. If you did get mild staining later in the season, an application of metal sequestrant will likely take care of it pronto.
If there are trace amounts of iron in your source water, you might eventually need to sequester but it could literally take a few years to build up at that rate.
THANKS! The above is who I turn to with questions like this. She has learned how to take care of metals in her pool water by the seat of her pants and doing much experimenting and using science to make sure it is a solid plan!

Are you SURE it is at 100 and not over 100? Here is something you can do to make sure:
"Add pool water to bottom of sticker.
Add tap water to top of sticker.
Shake.
Pour out half so mixture is to bottom of sticker.
Add reagent to top of sticker.
Shake.
Test outside with back to sun and tube at waist level.
Pour back and forth a few times to see if you get the same result.
Double the result. "

Think long and hard about what you wear on your feet when you go out to brush. I would do a "test" to make sure you will not leave footie prints!
OH NO on having the spa so close! At least you know what to do so.............
By pouring the pool water (has CYA in it) to the first line and tap water (does not have CYA in it) to the second line in the bottle and mixing it you are halving the CYA. You then pour half of that out and do the test as "normal". Once you have the results you will double it. This will show us IF your CYA is higher than 100.

Hello again...I might adjust my advice slightly - I hadn't realized it was new plaster as it was verrrry early when I read in yesterday.
Since its new plaster, there is specifically a product that will both sequester mild metal AND help with the plaster dust...its not HEDP based like the usual sequestrants we recommend. Its called Jacks Magic Magenta (not pink or purple, they are different products.)
While you likely don't really need this given the extremely low level of metal, it still might be worth a single application to help collect the plaster dust and also help on the off chance that adding source water increases your metal level a bit. Preventative as opposed to active treatment![]()
When you have something like that on your water you can try putting a small t-shirt or such over the net to help catch it.
I can't wait to see if the GLANCE method works better for you. It saves my sanity so......it is all good!

I've also read that you.can float tennis balls in the pool to absorb some oil and sunscreen but I would defer to the experts as I am still in research mode.I tried putting one of my hospital hair nets that I use for the skimmer on the net, but the water took too long to drain from it so I got rid of it. It took a while to get rid of the film, but I think I got most of it.
Also did the 1/2 and 1/2 method with the CYA test and it looks like it’s truly sitting at 100. Will that go down with water evaporation, or does it just get more concentrated?
And my husband wanted me to ask on here how to get rid of sunscreen stuff from the water surface? I’m sorry for all the new questions. I seem to always find new ones when you answer one.![]()
