You need your own high-quality test kit first. It's pointless at best -- harmful at worst -- to make decisions based on unreliable pool-store testing.

Good morning. I see why Drew made that comment based on your signature notes about waiting on a test kit. We understand your season is almost over, but it's also true you can't rely on the pool store testing, so be very careful about taking any action based on their word or test results. Last I heard the Taylor K-2006C test kit was expensive up there. Your only other option is to travel south across the border if you have a PO Box or friend who can hold a TF-Series test kit order for you. Keep in mind if you did order a kit now, it would be good and available for next season if stored properly in the house. Just a thought.

But to answer your basic question - "No", you don't have to go out of your way to lower the TA of 110 if the pH is stable in the mid-7 range.

As Pat said, Your ta sounds like it’s fine where it is if your ph is stable.
If your cya is correct then you’re riding minimum with your fc which is not advised as it leaves no wiggle room between you & algae if any little thing happens like a higher bather load, high uv day etc.
Target range is where you want to be


This is hard to measure & subsequently maintain without an fas/dpd test.
We also recommend reaching slam level for your cya & doing an
Overnight Chlorine Loss Test before closing to ensure you close algae free &

& open that way too.
These things require accurate home testing so the kit is not a waste. The reagents are good for 2 years. You’ll likely run through those well before their expiration.
Is the water 60 degrees & falling in August there? If not then you’re closing too early. Is it still 60 degrees or less in June? If not then you’re opening too late

I will work on getting a kit. Aug is typically still pretty hot in Winnipeg so we don't close it till close to Oct but we typically don't use it anymore once it gets to second week of Sept (we stop heating the pool as the temperature over night is in the single digits by then)

It’s really pointless attempting to adjust your alkalinity without a decent test kit, you don’t really know where you’re starting from or where you finish.

The pH holding steady at 7.4 is a bit unusual unless you’re using dichlor or trichlor, both of which will add CyA. If you switching to liquid chlorine keep an eye on your pH as it will start to rise without the acidic nature of the dichlor or trichlor.
