hW Marinemix Professional 150 gal, Synthetic Aquarium Salt

Great stuff! Mixes clean, as with any salt mix the entire batch at once or make sure you mix up the salt before each batch ( put it in a 5 gallon bucket and roll it on its side)

I have just purchased this salt. I am using a salifert ALK test kit and found out that the ALK levels are super low. They are reading out to be 3.5 ALK. This is a brand new salifert test kit that I recently ordered on Amazon, so there is nothing wrong with the test kit. I am very disappointed with this salt because I had heard great things from BRS (Bulk Reef Supply): "BRS recommends using a complete salt mix, to save money and time on testing supplies and major element adjustments. Upon BRS analysis - hw-Marinemix Reefer contained Calcium at 445-450 ppm, Alk of 9.0 dKH, Magnesium at 1380 ppm."

Get what you pay for....Great salt! My corals love it and my tank is very stable. I have used Instant Ocean in the past but will never go back after using this salt.

This salt brand is amazing, however this seller shipped poor quality salt. Would not re-purchase from this seller.

Good salt. Mixes completely in 10 min or less. Bucket is clean when done, no clay or residue.

Great salt but i recommend the reef version over this one

Great
