In a 10 ml sample, add 10 drops of the R-0010, mix well. Then add 3 drops of R-0011L, mix well. If sample is clear, add 2-3 more drops (as a test) of R-0011L. Let us know if you see any color.

Also, double check the reagent numbers on the bottles - not just the blue caps.
R-0010, R-0011L, R-0012

What is speedstir????

What is speedstir????

It is an electronic stirring device.

It makes testing much easier and consistent - no more swirlijg between each drop of reagents.
There are other stirrer options to the Taylor device as well.

So you do know we are in Texas and do things the hard way right? So how does this make your testing more accurate?

I don't pay attention to the caps when testing. I always check the reagent numbers before adding

Maybe just in Ozona
Since the stirrer is automaticlly mixing/stirring, you can concentrate on adding one well formed drop at the rate of one per second. Easily repeatable amd no more hand swirling between each drop.

Some have considered it a gimmick - until they started using one. Now they won't give the stirrer up.

Has your kit been stored indoors except when in active use?

I will look in to the stirrer. Test are stored inside in a closet unless in use.

What color did it initially turn?

Test your tap water to see what it shows.

 

[JamesW]

Using the 25ml and it is clear.

Clear/Colorless indicates a bad reagent.

Did you swirl the sample thoroughly after adding the drops?

If the water and reagent are cold, the drops do not disperse very well on addition.

Maybe the reagent is stratified?

Try gently turning the bottle a few times to mix the reagent.

If no results, replace the reagent.

Yes I swirled throughly. It went from red to clear which it has never done before. Usually goes from red to blue.

It started off red but it went clear instead of blue

I will do that. Just very weird that I have always had CH and then over night, ZERO!

 

[JamesW]

Your CH is not zero.

Your test is not working correctly.

The problem is some type of testing error or interference.

Maybe a compromised reagent or maybe an interference from something like copper.

Does that just happen over night though? I have been using this reagent for several months with no problems. I will test again this afternoon and see what it shows

Well, we know that the calcium hardness cannot just disappear unless it is removed somehow like a reverse osmosis treatment or maybe if you added a lot of TSP (Trisodium Phosphate) to drop out all of the calcium.

If you have an autofill and a leak, then the pool water CH will go towards the fill water CH.

If your fill water has a zero CH and you have replaced all water, then maybe the CH can be gone.

The sample going clear/colorless indicated a compromised reagent or an interference.

Maybe the reagent froze or got too hot and is ruined.

Maybe the water has a lot of sequestrant, chelant or maybe a lot of copper etc.

So, there has to be a testing error of some type.

Maybe a compromised reagent or maybe an interference from something like copper.

The reagent has been stored in a closet inside. It could be user error but I will test again today

If you ran a basic metabolic panel (BMP) on a patient and one or more of the results came back with a zero reading, would you believe the reading or would you question the reading?
