CYA, FC... Max?

[Rancho Cost-a-Lotta]

1. For testing FC and/or TC, when running a high FC like I need to, do you just dilute with 50% tap and multiply readings by 2 using the K2006? (like the high CYA testing method)

Are you using a 10 ml sample for FC testing?

There are two sample sizes you can use for the drop-based FC test; 10 ml or 25 ml. Using the 10 ml size will save your reagents. Add one scoop of powder. Multiply each drop of R-0871 by 0.5 (divide by 2). You'll still achieve enough accuracy.

The Taylor K-2006 kit is a little light on chlorine test reagents. You should consider ordering refills of R0870/R0871.

You need to drain at least half of your pool volume and refill.

1 - No. Tap water has chlorine in it. You can try using distilled water, but your test error will be well over 20%.
2 - Use % sodium hypochlorite for bleach concentration.

Distilled water seems the better option... forgot about that. Even then still 20% or more?

Any better options for testing high FC levels in my situation?

Also - plan to drain at some point, but not in the plan right now (logistics, equipment, and volume of water is causing issues doing that much)

I agree with Mike - just use your FAS-DPD with 10 ml water sample. You will need to get some reagent refills.

Drop based, 9ml, DPD. And digging it looks like mine is the K2005, not 2006 (updated/edited... my sincere apologies - going off memory sometimes sucks!)

Reading the instructions it mentions repeating test with 4.5mL tap with 4.5mL pool water and re-reading to get approximate. Would guess that distilled instead of tap would yield close enough results for this purpose... thoughts?

K2005, not 2006

You need the FAS-DPD -- the one you have is not accurate at all.

Thank you as well for all the help too (didn't mention that sooner). And the video on shock confirmed a lot of my "suspicions"...

 

[colsoncj]

I'll working on getting the equipment to do the FAS-DPD method... til then how inaccurate are we talking when it comes to the DPD method?

 

[mknauss]

At best it will tell you if you have chlorine. It might imply you are above 5 ppm or not. But that is about it for accuracy.

and would require me sourcing a pump to even get 50% out

With an above ground pool, you can use gravity to your advantage. I have drained my pool rather effectively just by siphoning through a vacuum hose.

I actually was considering that... but with a couple garden hoses. Vac hose definitely would be faster. Appreciate the heads up!

Given we have a housewarming party not to far out, and still so-so weather, may wait until heat of summer to drain/fill so I don't flood my already saturated yard from spring rains, and so warmup time is a lot shorter! Also gives me some time to confirm CYA levels more and get a better idea of how much drain/fill we are looking at.

You can order the FAS-DPD test separately and then your kit becomes the 2006 in effect. Here it is.

Saw that too... Good find. Also similar to what Marty shared...

Since I have the test cylinder (large one in K2005 would work) and 003 reagent already, would only need the 0870 and 0871 reagents to be set I believe...

 

[DeanP66]

Absolutely!!! You now would have the K2006.
