Title: Readings are High Again
Post by: cappykat on November 10, 2005, 09:58:01 am
Yesterday when I refilled, I checked the water and everything was perfect.  I just checked today and the pH and Alkalinity is high again.

I'm using AquaChek test strips.  The pH seems to be between 7.8-8.4 and alka beween 180-240.

Should I add a couple OUNCES of pH Down??

Yes.  That should do it.

Now I'll wait 24 hours and test again?

How does your calcium hardness reading look?

You should take a spa water sample along with a tap water sample  to a local pool and spa store that does water testing and have them test for metals. Also check the date on your test strips to see if they have expired.

Yes.  What are you usin to test? 7.8 is high, but tolerable, 8.4 is just high.  The alk readings are ok. If that were my tub, and I thought the reading was 7.8 I would leave it alone as my PH tends to drift down over time.  If I knew my PH was 8.4 I might try to lower it. I'm currently out of PH down, so I might give the White vinegar a try. High PH is not something I normally see.

You do not have to wait 24 hours.  Run the jets for an hour or so and then test it.  2 hours should be sufficient.

AquaCheck paper test strips.  It's a match the colors game..HA!  The hardness was within normal range and the bromine was normal.

I say pH is between 7.8-8.4 because the pink is between those ranges.  I would say it's on the high end.  I put in 2 ozs. of pH Down and I'm going to wait to check it late tonight or tomorrow morning.  Husband will probably use tonight.  I'm sick with a sinus infection so I won't be going in.

Make sure the tub is running after adding the ph down, so, you do not drop your alkalinity. You can check in a couple of hours.

When you say "run the jets" does it matter if the cover is up/down?  That's probably a stupid question, but I don't know if it matters.

You can run the jets with the cover on.  If you run the jets with the cover on alot, the increased condensation will make the cover heavier over time. The way I do it is if I am home I leave it open and if I have to leave I keep it closed.

I leave the cover 1/4 open (3 piece cover); I think it is most important to do so for an hour or so when shocking but I do it when adjusting ph also.  One note:  If jets are on with air valves open, the aeration can give "false" high ph readings.  I've been battling high ph for a couple weeks, and I add ph down, run all pumps for 15-20 minutes, wait an hour and retest / redose as req'd.

Cheers!

Cappy;

You didnt mention what your chlorine or bromine reading are.

I mention this because I find one very weak aspect of test strip and lower end test kits (ones without thiosulfate (chlorine neutralizer)) is reactions with chlorine.

If your chlorine is high, it is quite likely that you will get a high pH reading even if your pH is OK.

A nicer test kit or store lab will test your chlorine before the pH to determine how much neutralizer is required to get an accurate pH reading.

I don't know much about math, but how do you leave a 3-piece cover 1/4 open?  That must be calculus or one of those other Chinese words.

Maybe its a three seamed or quad-fold cover....

What is a better test kit to use?  I just checked after 2 hrs. and hardness and bromine levels are within normal range.  The pH and alk is still high (same #'s as before I added 2ozs. of pH Down.  I'm going to take a water sample to the pool store and see what they say.  Should I do anything else in the meantime?  
Title: Re: Readings are High Again

I wouldn't do anything else at this point.  Take a spa sample and a tap water sample to the pool store. Between the two they should be able to resolve your problem.

Simple really: put one seam in the middle; split one of the 2 halves into 2 again giving you a 3 piece cover with a small (approx 1/4 size) section to open and add chemicals etc.  Standard Maxxus cover... ;)

I got sick of trying to decipher the colors and bought this:
http://cgi.ebay.com/Hanna-pH-TESTER-METER-Aquarium-Hydroponics-Lab_W0QQitemZ7559090510QQcategoryZ58191QQrdZ1QQcmdZViewItem.

Sorry for promoting a product.  I have no ties to it other than I bought it and it works well.  It comes precalibrated.  Our temps and pH range are not extreme enough to worry about compensating for those attributes when reading pH off the meter.  It's great.

Just came back from doctor...sinus infection so I'm out of the hot-tub for a few days.

Thanks stl-rex.  I'll check out that website.

During this time of year pumpkin is a very popular choice. However, you can never go wrong with apple.

Hope you feel better soon!

Wouldn't the steam from the spa help you feel better?  Why do you have to stay out of the spa?
