[RUDY850]

Hello.

whant to test.

PH

AL

Hardness

MPS

TDS

Free available chlorine residual

will be using the nature 2 and the

way they recommend the treating of the water

dichlor will be used for shocking.

Is there a test kit that test all of the above or are separate kits needed.please recommend best way to go about this.

THANK YOU.

First off, anyone posting to this site should go to adblockplus.org to block ads (thank you Dr. Spa for that suggestion). The reason is that the latest ads on this site that appear to float in the middle right of the screen prevent the "Post" button from working -- basically anything in the columns below the ad are disabled and the cursor is not seen by the web page. Hopefully the administrator of this site will fix this; otherwise, posting on this site will become impossible.

As for a test kit, the Taylor K-1005 or K-2005 would work for you as it is less expensive and you probably don't need the FAS-DPD accuracy of the test. MPS will show up on the test though you can get separate MPS test strips if you want. The test kit has a CYA test that you don't need, but it seems to be paired with the Calcium Hardness (CH) test that you do need. You shouldn't need to test for TDS. The test kits test for pH and Total Alkalinity (TA).

The Nature² Spa Mineral Sanitizer Owner's Manual says to dose 1 tablespoon of MPS per 250 gallons so on the chlorine test that would be equivalent to about 4 ppm of chlorine.

Thanks for the information.

I ended up getting the k-2006 kit.very nice kit I have to say.

Yes, that's the normal kit we recommend though it's primarily for chlorine users. In your case, you would add the R-0003 reagent so that the MPS would show up as Combined Chlorine (CC). It may not show up as Free Chlorine (FC) if there is no chlorine at all in the water.

Your last comment just gave me a question.

I know one of the Taylor 2 series kits, 2005 or 2006, or 2105 or 2106, is suitable for both chlorine and bromine, while the other is only suitable for chlorine but not bromine. Please let me know which is which.

I am currently using chlorine in an older spa (1989) that has always had chlorine. The spa sits for a week or two at a time without use or testing. I have considered switching it to bromine for longer lasting sanitizing action of bromine in heat.

Also, the Taylor website refers to "most" spas being treated with bromine while "most" pools are using chlorine. Is that a standard or is it personal preference? Or, in my case, a matter of timing?

Thanks for the great help this forum always provides.

You want the versions ending in "6" since those use FAS-DPD tests that can measure much higher levels and are more accurate. Both the "20..." and the "21..." tests can measure chlorine and bromine, but only the "20..." test can measure Combined Chlorine though you can get one additional chemical to do that. Also, the "20..." test has tests for Cyanuric Acid. So the K-2006 is the broader test and you can still use it for testing bromine if you want.
