Green water help please!

(1/1)

jeng845:
I initially asked this in the Marquis forum but then realized this might be the better place for it:
I'm hoping someone can here can help. I have a brand new Woodstock Elite, which I filled and then took water in for a test - was told what to add (alkalinity, followed by calcium). Water turned green as soon as I raised alkalinity.

Here's what I've tried to fix it:
1. dry acid to lower alkalinity
2. shock
3. pack of Brom Start
4. empty/clean tub and filter/restart
5. (try to get alkalinity to normal level and boom...it's green)
6. switch to chlorine filtration
7. had install guys come out - they said they'd fixed it. Water is still green
8. added sodium dichlor
Water is still green. I've had this hot tub for a month and have only gotten to use it twice. Does anyone have any ideas? When I test, all levels come back normal (calcium is potentially a tiny bit low but that's it)

castletonia:
Not aware of high alkalinity being able to turn the water green.  Normally green water means either copper in the water, especially if the color change occurred quickly or lack of sanitizer if the color change happened over time.

If you have a ton of metals in your water alk can turn it green. Try using metal gone before you adjust alk.

Yep, definitely try a metal control product and make sure your ph and alk are in the correct range.

MarKee:
I can assure you there is nothing wrong with the tub, there is something in your water.

1.) Are you on well water?

2.) If not, does your city water have metals in it?

If the water stays green, you may need to pick up a 5-stage fill filter and re-fill the tub.  You will also want to use a Metal & Stain remover product after re-filling.
