Help with sodium phosphate

[Steamreefer]

Having trouble finding the "right" sodium phosphate to dose in my reef tank. Seems as though here in canada we dont have as many options on Amazon as they do in the states.

I found this 1, looking for clarification whether this is the right 1.

Clearly this 1 is marketed at growing plants/flowers

Not sure about the one you found. Can you get trisodium phosphate by loudwolf delivered to you? It’s a food grade product.

Is potassium also low?

Haven't been able to locate loudwolf here. As far as potassium is concerned I really have no idea I dont have a test kit for it. Im assuming what im looking for has no potassium in it?

I swear amazon.ca has EVERY sodium (insert substance) EXCEPT just plain sodium phosphate

This product would be great, but it’s pricey and is enough for many reef tanks.
