This product is extremely confusing to me as the label on the canister states that each gram of Remineraliz-P will increase the GH by .57dGH.
However, on the website it states that each gram will increase GH by 6.7dGH!
This is a very big difference.
I added this product according to the label and found that it did not dissolve fully.
This is very confusing...
Sorry, I cannot answer that due to the fact that when I used it, I was testing the water after adding, and using a TDS meter. I would use a jar, put ro water in it, put a scoop of remineraliz in it, then shake til dissolved, then I would add to my 5 gallon jug of RO, test the TDS, and go from there.
It was a while ago, but i believe I added until 120ppm of TDS, which was around 5 GH. I did not measure though.
