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!
