Help identifying a Chemical

[aceniza]

Hey all,
I had a bucket in my shed and I must have forgot to label it. It does not appear to be as soft or fine as Sodium Bicarbonate when put side by side.
Side note - I have another unlabeled bucket that looks to contain sodium bicarbonate - is there any way to test it?

Any guesses?

Maybe CYA?

Maybe out a tiny bit in a gallon of tap water to dissolve and then test for CYA.

It could be, but my CYA (Puri Tech) is in flakes or chips, similar to Calcium Chloride. Maybe it's an older stash I forgot about...

I think it's sodium bisulfate. That stuff clumps like crazy when exposed to moisture.

I wouldn't suggest using it for two reasons: First, you don't know what it is for sure. Second, you don't want to add sulfates to your water as they can attack the metals in your SWG and shorten its life.

Well it hit me lol

Im 99% sure it’s TSP. Because I bought 2 boxes and put it in a bucket, and I currently do not have any other unidentified buckets.
