Is the DPD Kit made by Taylor (sold at Leslie Pools) not same type of chemical testing as the HTH taylor K2006?

I wanted to know cause it seems I have a 5 way Kit and I am only missing the ability to test for CYA levels. I need to gain that ability to test soon cause I am going through the bleach and have only added the CYA that would be in my Trichlor tabs for the last few days.

Is there a decent stand alone CYA kit I can get so I dont have to repurchase the whole thing?

Also how would I calculate a best guess to get my CYA to 30 ppm for a pool just under 2000 gallons?

Thank you again in advance.

No. The K-2006 is a FAS-DPD kit. It can test chlorine levels up to about 50pm I think it is. A DPD kit can only test to 5ppm. There is a stand alone CYA kit (Taylor K-1721) and a stand alond FAS-DPD (Taylor K-1515) which you can get through the test kit page in my signature below.

I don't use trichlor pucks and in your small pool, it is gonna be kinda hard to judge how many pucks will get your CYA to 30. I guess you'll just have to check it every so often, but you'll have to monitor it. It won't take long in such a small volume of water. Also, I think you'll do better with a CYA at 50 rather than 30. A too low CYA makes it hard to keep chlorine in the pool especially on a hot sunny day.

I have some stabilizer that I would like to add because I am pretty sure I am low since the pucks have only been floating for a few days. And they don't seem to be able to keep the Chlorine levels up throughout the day. How much CYA do I add to get to 30ppm (assuming I am close to 0) for a 2000 gallon pool.

Is there a CYA calculator for this?

It should take about 7 ounces of CYA to take a 2000 gallon pool from 0 - 30 ppm of stabilizer....

The calculator that we're using is called bleachcalc, and it was developed by mrsmith, a former member of the forum, and further refined by a current member of ours, chem_geek. http://www.poolforum.com/zxq/BleachCalc262.exe

It is a chlorine calculator, but if you'll look in the upper left hand corner, there are other calculations that it does, as well...

Thank you guys so much! Really appreciate it.

Just FYI -- I helped with The Pool Calculator, but didn't have anything to do with BleachCalc. Michael gets all the credit for that app. Note that there is one error in the app with respect to borates so don't use it for that calculation; for everything else, it's fine.

My mistake...... I stand corrected.

[GeorgeMccarthy]

So it looks like my CYA is almost 30 ppm now but not sure cause test tube starts at 30 and I can still kinda see outline of black dot.

But I just wanted to confirm that based on the Best guess chart, if I my CYA is between 30-50 ppm. Then I want to have the free chlorine between 3.0 and 6.0 ppm?

Think i need to get that FAS-DPD add on kit then cause mine only goes to 5.0.

Also If I wanted to support the forum, is there a link i could click to purchase the appropriate unicel (A) filters on Amazon?

Thanks again. You guys are amazing.
