“I've been running my 90 gallon reef tank with lots of softies for about 15 years. The Sea Lab #28 have been the only product that has been able to keep my calcium right at 430. It doesn't move. I put one block in my refugium in an area of medium to low flow and when it dissolves - then replace it with another one. My alk is right where I want it 8 - 9. When I was using the liquid chemicals and trying to dose manually (before that) - I've never purchased an auto-doser, I was always chasing my calcium levels.....too low, then back up, then too low, etc… I'm very happy that I found it because it works for me. I've never seen spikes with either Alk or Calcium. They stay right where I want them. When the block is almost gone I replace it with a new one. I'm just about to order another box. I found this stuff about 2 years ago and it has really made my life much easier for keeping my ALK and CA right where I want them. You're mileage may vary, but I'm ordering my 5th or 6th box and will continue to order.” – smcdonald
