2 questions (CH and PH)

Jump to latest Follow Reply
hey in all honesty I got another question. when they opened me yesterday my builder's son-in-law gave a big push on phosphates. almost like I have em or will get them eventually. he actually said no matter what eventually you will have an issue. i never tested for phosphates. i read the pool school article and i'm confused. it says you treat with this threshold. . .

"The threshold limit for phosphate removal is around 1000ppb (1ppm), there is no point in removing phosphates if your phosphate level is below a 1000ppb"

so if i test and it' literally isn't 0 ppm then i would need to treat? the taylor test kit does this:

"The Taylor K-1106 test kit can test at phosphate levels of 0-1000 ppm or 0-6000 ppm. It has two different color comparator cards for the two tests."

so am i reading it right that you got to be at 0 or you should treat? he got me all worked up about it yesterday. i didn't mention last night cause i was concentrating on getting up and going.

I liken phosphates to the aisles of dog food at Petco. Never once have those aisles spawned a dog because of the food on the shelves. Now. Open all the cans on the floor and leave the front doors open when you go home for the night, (get lazy with sanitizing), and all of a sudden dogs/algae might become a problem.

A testament to how much you should worry about phosphates. (y)

Now. Horribly mismanage your chemistry with unreliable once a week testing and even less dosing, and. Well. Good luck with what the pool stores tellin ya. ;)

You know the drill when they blab about something. Smile and nod and thank them for their concern. Then go right back to what you were doing.

i totally did after i said to them to get their bottles of chemicals away from my pool decking. lol i mean come on. why dump algaecide and whatever else was there into a clear pool?

This is a phenomenal analogy! And I'm just picturing 100's of dogs in an aisle at Petco!

I tested my pH free chlorine and calcium hardness being that I added a little bit more calcium hardness the other day and my CSI is now sitting at -.6.

My water temperature also is climbing as the days go on as we know it will continue to climb

So my question for you guys and I probably know the answer already. I should probably not add any more calcium Hardner, and let it sit where it’s at because my pH is only gonna continue to rise, which is going to improve my CSI and also the temperature of the pool is also going to increase which will also improve my CSI so I should be pretty much in that -.3 range real soon.

Sounds good. Adjust the plan as necessary. :) When the April showers get going in full swing, some levels may need replacing.
 
Looks like You’re off to the races 👍🏻
Just jumping in to say, don’t sleep on poolmath- check out the summary feature with customizable ranges (its in the hamburger menu). Beats thumbing through a notebook any day to see what things were like this time last year or how much of this or that you’ve added this month etc.

There is a small but not insignificant typo in that quote. The correct statement is:

"The Taylor K-1106 test kit can test at phosphate levels of 0-1000 ppb or 0-6000 ppb. It has two different color comparator cards for the two tests."

Yea thank you. I thought I was reading it wrong too but figured it was a typo.

Mods. That’s how it appears on the site in pool school stuff. I copied it right from the phosphate article.
