Unsealed. 1/2 full. Mystery powder
Container was 1/2 full and not sealed. Didn’t mix well with ro/di and honestly I’m not even sure someone didn’t buy the container. 1/2 fill it with baking soda, then close it and return it.

It would rate better but the dosing instructions are at best described as poor and intentionally confusing.

Very shady receive the shipment in the product box just tape shut when I opened it you can see the lid wasn’t even screwed on correctly and the safety seal was wide open there was powder over the outside of the container before even inspecting to see the seal so for all I know this is just straight up baking soda because it sure looks like it
