I use their Matrix, Cupramine, Mag, Reef Builder and Reef Advantage Calcium and will be trying their salt mix when I run out of Reef Crystals. Anyone use their salt mix? They have a new low price on Drs. F&S for the 200 lb box ($47.69, free shipping if you order something else to get to $50)
I know I could get other brands cheaper but I like them. When I have called them they have the best customer service. Sometimes I just like supporting a company with such good customer service and I feel like I can trust their quality and that's worth a few extra dollars to me. Just like you go to a restaurant that's clean and the staff is nice to you instead of going to the cheaper place down the street.
