Greenish Hue

[JcDenton]

I need some advice from those in the know.

In the past 9 months I have not had any problems maintaining my water. Two weeks ago I did a full-water change, however when I finished re-filling the tub with fresh water, I noticed a greenish hue to the it. It was very subtle and at the time I was not too concerned.

Two weeks later and I just can't seem to get my water clear. All my levels check well. I have re-read many older posts that discuss this issue and have tried to rectify the situation on my own but without success.

I am on city water. While the quality of this water may fluctuate seasonally to some extent, I had always believed that if I could drink it, it was ok for the tub. I had always believed that our water (city) was pretty good. My question - could this be contributing to my troubles? My existing water care routine has not changed and it is only my wife and I in the tub. Has anyone else experienced this on some level or should I be looking elsewhere.


Thanks all - I appreciate the time

Every time I do a water change, I too have a slight tint of green water. I balance my water etc,and within 2 days,it's sparkling clear.  I have little clue as to what would cause the green water hue. I do know,that using various amounts of "lead" in glass,will give you lighter/darker green glass,dependant on the amount of lead in the glass.

Just sharing my experience with ya.  Chemical wise........

Calcium Hardness,190-230   ALk,90-120  PH,7.4-7.6  I use a Nature2 cartridge within my filter,and dose Di-chlor after water change,4-5 teaspoons,and after each use,2-3 teaspoons.  Bout every 7-10 days, I shock the spa.   Every 6 weeks I change the filter.  4-6 monthes I replace the Nature 2 cartridge.


GL with it,and if you figure out what and why causes the greenish hue,please share with us all.

I'm considering another full-water change but I think that might be a little aggressive. I do not like the greenish hue but what if the water I use to replace is also greenish? Would be a big waste of water.

Before I do anything I would like to know that I've at least tried to understand the reason behind the problem in the first place.

Thanks auto

I'm a little confused on the difference between di-chlor and MPS.

When you say after every use you throw in 2-3 teaspoons di-chlor... 7-10 days shock. Does shock mean just adding more di-chlor or sanatizer(mps)?

I'm a little confused on shock which I think is MPS and Di-chlor which I think is sanitizer?

Are you guys using a stain and scale or metal gone?

[HotTubMan]

Two things.

Sometimes when 0 sanitizer is present with ozone and sanitizer is added, it can turn the water green/yellow. Itwill go away. Dont let your sanitizer reach 0.

Secondly, and this may sound silly, are their trees over the spa? The ocean/lake looks blue because it reflects the sky. Sometimes spa water looks green because it is reflecting the vegetation from above....

[JcDenton]

I do not have ozone. The water that is green is coming from the tap. I was curious if anyone was familiar with this phenomenon. I sense that it may be due to seasonal weather changes - not sure.  As for the tree, no - we're good that way. (but the thought had entered my mind when I first noticed)

Stuart - you mention stain, scale and metal. Up until now, these are words that I have quite ignored as I assumed they did not effect me. Now I'm not so sure. I have stuck to a  very basic KISS system that the dealer set us up with - floating bromine pucks (no ozone) and shock as necessary. This has worked flawlessly until just recently. I had thought that metal/stain etc were more for hard water/well water situations. Possibly you could fill me in or I could search on my own - either way -thanks for the input!

Jc,
Try some stain and scale or metal gone at refill and you will probably get rid of this. I have found that 2 things cause a green tint....Mineral or organic. Usually if it is organic it will be a cloudy green and hard to see the bottom of the spa. If it is mineral the tint will be just water color with less particle.

If your getting a mineral tint use a sequestering agent like the two I mentioned. If it is organic you can usually cure it with a good shock and let the spa breath an hour or so...

If it is organic you can usually cure it with a good shock and let the spa breath an hour or so...

If this STILL dosn't work, get one of the concentrated polymer clarifiers and dump about 5 caps in your spa while it's running. If anything is suspended in the water it will clump and come out. The polymer will take about 3 days to stop working, so don't be suprised if small bits of stuff still clump on the surface when you are using the spa after you treat it.

Good luck!
