So my local general store ran out of MA and I have more on order, but nobody else in town carries any and I really need to keep working the pH and TA down on this new pool, short of going all the way into San Antonio which isn't going to happen today. I bought 5 lbs sodium bisulfate from Walmart, and I realize that this puts sulfates into the water which can lead to corrosion overtime and is not recommended for a SWG. I just wanted to know if the 5 lbs I bought would really create a huge issue with my equipment if this is just for emergency scenarios? Here's my latest chemistry from today, and I use the ever hated Lamotte ColorQ Pro 7 (which I love BTW but that's another topic altogether).
