15,000 gallon IG plaster Alkalinity here is naturally high out of the tap, pool tested at 220ppm. Their test said pH was 8.2, all mine say it's...
Is it okay to keep the alk in a vinyl liner at 130-140 if the PH has stayed consistant at 7.5?:confused:
This might help to start off knowing your water. 'Hardness' is related to calcium hardness and alkalinity. We recently moved west about 90...
I read a post that talked a bit about TA numbers that could be misleading due to high CYA making up the chunk of the TA. Is there a calculation that...
Is there a "grocery store" source for adding calcium?
To aerate when lowering alkalinity? My fill water is high alk. Tests at 320. 3 times this year I've added acid and tried to lower it. First two...

Yesterday afternoon I noticed a very slight yellowish tint on my pool walls so brushed them down and saw a slight yellow-brown cloud go into the...
I realise that Calcium is usually present in fill water. Our fill water is about 190-200. I understand that as water evaporates and new water...
It was my understanding that bleach use would eventually cause PH to rise, but will it also increase Alk? A few weeks ago I had my Alk down to...
I am new to learning about pools and am trying to get the constant algae out of my pool. Last weak in trying to learn about my pool I found the PS...
I have an inground, vinyl liner pool (new liner last year) without a heater. I just had my water tested. Everything was OK except the TA measured...
The test printouts from two different pool stores I've used show a Total Alkalinity catergory and an Adjusted Total Alkalinity category. Sometimes...
Just read another post referring to the Wal-Mart 5-way test for hardness. The post mentioned multiplying the result by 50 to get the test result. ...
First off: 16 x 40 IG vinyl, about 6 weeks old. I seem to have a problem with PH wanting to sit around 8 or above. My TA is 90. When we first...
I am still trying to get my alkalinity down. I have an above ground pool (about 5500 gallons) 18X48. My alkalinity readings are still around 280. ...
This is a question about Calcium Hardness...Pool info: 12,000gal IG exposed-aggregate surface. Pool store test says hardness is 185ppm. My...
Ok, my PH has been creeping downward and is now low enough that I can try to lower the alk. Not sure why it's creeping downward. But, since it is...

Hi guys. I'm currently draining my 15' Easy-Set "kiddie pool" (that I filled yesterday) to more perfectly level the ground underneath it. But in the...

Initially, I think not. The day this measurement was taken I also had a pH of 8.2, and TA of 136. If it were to be trusted, the Saturation Index was...
