Dry Acid vs Muriatic Acid

[drafferty]

Hello,
I really want to continue to follow the TFP/ BBB method as it has been giving me stellar results since I opened for this swim season. My question is what are the disadvantages of using dry acid over Muriatic Acid? Prior to joining the TFP website I purchased a 30 lbs. bucket of pH minus (sodium bisulfite I think?). I was just wondering if it is all that bad to use versus muriatic acid since I dropped $59 bucks on the stuff....I promise not to buy it again!

It adds Sulfates to the water. Long term use can lead to Crystals forming, but it wouldn't be the end of the world to use up what you have.

It's not bad to use occasionally, but using it will build up sulfates in your pool. This can be bad for concrete surfaces, tiling and other pool related surfaces. Read a synopsis here and you can download the full .pdf. Sulphate attack |

Since you've got it, use it. There are a lot of threads about it if you try the search box. Here's a recent one Acid - Dry or Liquid?

My understanding is it can also damage a SWCG cell.

I know the OP isn't using one, but I just wanted to put that out there for anyone else reading this thread who may be using a SWCG.
