High PH and Low Alkalinity?

[paigemetoo]

How do I raise my Alkalinity without raising my ph? My alkalinity is 75 and my ph is 8. I want to add baking soda but wont that raise my ph?

You have reported having a vinyl pool.

Don't worry about your TA yet. Make sure your chlorine, pH, and CYA (stabilizer) are right. THEN, check your calcium hardness and alkalinity. Unless they are too high, or unless you are having trouble with your pH bouncing around, neither are that important in a vinyl pool.

I have sodium bisulfate should I use that to lower my ph? My ph was good at 7.6 but because my TA was only at 60 I added 3 pounds of baking soda. Also should I be worried about my phosphate level and iron? my phosphate it is 300 ppb and my iron is at .4 ppm. I only know this because i had to buy cya because mine was not reading any with my taylor test kit so I had the pool store see if they could get a reading they got one of 20. The,y of course, wanted to sell me stuff to take care my phosphate level and iron but I am scared to do anything without talking to you guys/gals on here. My pool was a nightmare when I was listening to the pool store.

Thanks for ur help!

Yes, use the sodium bisulfate you have, until your pH is around 7.2, or until you run out.

Don't worry about the phosphates, but that level of iron can cause brown or orange stains. The stains don't bother everyone to the same degree, and they are not harmful in the slightest to people. But, until I know what you want to do about the iron, I'd rather have the pH low, which reduces the chance of staining.
