Title: Green Water
Post by: Snowbird on December 26, 2005, 07:13:13 pm
I swear that the water was NOT green when we put it in the tub.

But on Christmas Eve we noticed our water was turning green!  Oh no!  :o

When the dealer opened today I gave them a call and the tech said I probably have a case of algae and to throw a cup of Clorox in it tonight and stay out of it for 24 hours.  He is the mechanic and not the chemical expert, but he has seen it before and that was the cure.  The expert will not be available for a day or 2 (death in the family).

In the meantime, assuming this clears it up, how did this happen and what can I do to stop it in the future?

I would reccomend doing a quick search here on green water and a few things should come up.  I just can't remember what the answers are, but I know we talk about it from time to time.

One thing that pops into my head is... what color was the room when you put the water in the tub and have you painted it since (but perhaps didn't look till Christmas Eve?)?  Could the green be a reflection?

Sorry I'm not more help.

I remember I had a problem with "green tinted" water because I had metals in my water. When I added Chlorine, thats when the "green" happened. I doubt its algae, I read somewhere on here that algae needs "light". I would imagine you have a cover on your tub. Do a search on the boards and good luck.

Get your water tested, that will at least indicate if you have any metals in your water which could account for the green tint.  

Has the Clorox done anything?

The Clorox worked.  :)  The green is gone and it smells a little, but that should go away in time.

I'm still a little confused about how the algae started and survived.  I will check with the dealer 1st chance I get.

Thanks for the advice.

When you check with the dealer, take a water sample with you. The water test should be free, however, I have heard of some dealers charging up to 10 bucks a test.

Unless you leave the cover off or the light on all of the time, I highly doubt that it was algae.

Algae is a plant. Like any other plant, it does require some form of light for photosynthesis to happen.

My guess is it was metals that were oxidized through shocking or you are getting a condition that happens when you have 0 sanitizer for a period of time, sanitier is added and a yellow or green tint occurs. This usually clears up depending on how long there was no sanitizer.

Glad I can get my water tetsted for no charge.  The dealer who does it makes money off of all the chemicals I purchase, though.

The way I look at it, the dealer does make money off the chemicals, however, look at all the money wasted, if someone was incorrectly treating there spa!! Well worth it as long as your dealer is competant.

We offer:
"Free water testing to our loyal customers"

Simple enough.

If you want to buy your chems on-line, from HomeDepot or Walmart, get them to test your water...

That makes total sense. Since you will be most familiar with the chemicals you sell.  Its totally in the best interest of the consumer to use a reputable dealer for water testing and chemicals.

Just curious what dealers test with and if/how it is different from what I test with at home.  I bought my spa used from a private party so I do not have a dealer.  I took my water to Leslie's Pool and Spa and was shocked that they just used the test strips I have at home to test.   ???  Yeah, that was a waste of a trip to town.

I just put my high $ fancy computerized test kit in the trash!  I have maybe 2 or 3 people per month come in for water testing.  It usually consists of me taking a test strip, putting it in their water sample, and telling them to raise their pH and add more sanitizer.  Water care is just not that difficult and anyone who tells you differently is just trying to sell you something.

At my store we use DPD and Titrate testing and input the results into a computerized water analysis program that prints results and recommendations.

I use Palintest DPD #1 & 4 tablets to test for free and availible sanitizer.

I use Taylor thiosulpahate and phenol red for the pH.

For the titrate testing we use a combo of Taylor and Mursatt reagents.

It is rare that we need to test for metals, but we are prepared.

Once we get the results we plug them into the computer which will calculate the needed additions and provide the customer with a "perscription"

Term,

When you say you tell them to raise the pH you mean from acidy to basic right?  So, an adjustment would be frrom a pH of say 6.8 to a pH of 7.2, do I have this right?

Thanks

Yes, that is the proper terminology.

Ha Ha.  Very funny drew.  ::)  But I actually did that.. sort of.  The room is still under construction so all the lighting isn't in yet.  We tried checking it at night & couldn't see so I put the spa light on.  It sure was greener!  And the other colors didn't help much either.

Regarding light, the room has lots of glass but I doubt we were in the spa during daylight enough to start an algae colony.

The sanitizer is probably the answer.  I was not using it everytime we used the spa; just when the test strip said our MPS was low.  From now on I will put in 1 oz after every use.

Thanks to all of you for your help.  ;)
Title: Leslies
Post by: Gomboman on December 28, 2005, 08:21:11 pm
My dealer isn't really into water testing so I have to go to Leslies. My Leslies uses a Taylor Professional test kit.  The person who tests my water is very knowledgeable.  I would call and ask for the manager.  Most Leslies go beyond using test strips.
