First Taylor k2006 Test

[brewerss]

I did my first water test today and below are the numbers. My CYA test was not registering on the spectrum so I attached pictures of those results (I put 200 because I didn’t have a number to put)

These results don’t look great from what my poolmath is telling me. Where do I go from here?

It looks like a drain and refill or water exchange is in your future. To find out where you're at, do a diluted CYA test. Dilute your pool water sample with 50% tap water and test as usual. Double your test results to arrive at your CYA level.

My in-laws live in the Riverside (City). The city allows pool discharge into the sewer via your clean-out which may simplify things for you.

Ok I did the diluted test and still couldn’t get a reading. It was closer to the CYA mark on the side but not enough to estimate. Might be a silly question but how do I dilute further? 3/4 tap and 1/4 pool? Also did the other tests as well yesterday because I may not be able to drain for a while. Hopefully I can get everything else balanced! I filled the pool a bit then got my sample. After testing, I added about 15oz of acid.

At this point the CYA level does not matter much, you essentially need a full drain and refill.

To answer your question, next do 2 parts tap and one part pool water. Multiply by three.

If you need to dilute the pool water further then apply these ratios:

Pool water	Tap or distilled water	Multiply result by
1	1	2
1	2	3
1	4	5

Note that when doing a diluted test not only do you multiply the range of the test you multiply the error rate of the test, so results are a ballpark - not an absolute.
