Just thought I would let you know that I have been using Salifert for a couple of years but couldn't get one for testing alk so I ended up getting Red Sea. I have a mixed reef tank that is doing well and I thought that I had my alk at about 8.5 but when I tested with red sea it was 7.6. I was quite surprised and was informed by another reefer that Salifert always tests a bit higher. I went and bought another new Salifert alk test kit as well and it was still off by about 0.6-0.8 so just a little food for thought!
