Jun 26, 2010 · Every time you remove a lot of Diatoms you are also removing a lot of silicates. New glass tanks and sand substrate are high in silicates and can load the water so much that Diatoms will thrive for a month or two in a new set up. The more frequently you remove them the more silicate you are removing from the system.
