Plain calcite is by far the most used media. But if your pH is lower than 5.5, add FloMag to your calcite. Some maintenance is required with an acid neutralizer tank. Typically once a year you’ll need to add more calcite to your tank. Depending on your water pH and the amount of water you use, you’ll need to add more sooner.

How to Use a Trim Saw to Cut the Preform. A trim saw is a smaller tool that cuts away excess material until only a rough outline of the desired shape remains - the preform. Remember that you can't cut curved or bent lines - these saws only cut straight. To cut complicated or curved preforms you would need to use a Diamond band saw like the Inland DB-100.
