Recent test results:

FC - .4 CC - .2 PH - 6.8 TA - 250 CH - 270 CYA - 40

That was about 4pm yesterday. I aerated the pool and brought the pH up to 7.6 when I checked it at 9pm. I poured the recommended amount of muriatic acid before bed, then aerated again early in the morning. pH was 7.4 this morning. This afternoon it had dropped to below 7 again.

I’m trying to get my TA down but I don’t understand why the pH would be dropping over time instead of raising.

The chlorine is another issue. I’m going through gallons of the stuff weekly. I guess it’s fighting algae and I plan on doing the SLAM soon, I just haven’t had a chance yet. I think I need to bring my CYA up as well because the pool gets a lot of direct sunlight.

Any pointers?

Your pH should be rising quite fast with a TA of 250ppm and not dropping. Something doesn’t make sense. You are using the Taylor test kit and got the test provider down ok?

That’s what I thought but I don’t know what’s going on. I got the Taylor k2006c about 2 weeks ago and have been taking a cup of water from the pool and doing 44ml with 5 drops of reagent.

44ml? Check the instructions again. It should be 10ml for high TA and 25ml for normal TA range.
 
While you are figuring out the TA testing, I recommend you shift focus to your chlorine.

With a CYA of 40, your FC should be over 5 and never ever ever below 3.... you are at 0.4. FC should be your #1 priority... TA is typically the least important metric.

The FC may actually be higher if a 44ml sample was used by mistake for that test as well. Would be good to double check all of the tests.

Edit: or it might be lower if the water sample is too large?

Yes, I was confused about what he was asking. I’ve been using the proper amounts of liquid for the tests but I will go back and make sure I’m doing it correctly this afternoon.
