Glutaraldehyde and autodosing
Some folks add Glut to their fert solutions for autodosing. This means Glut makes contact with water used to make solutions.
When Glut is added to an aquarium it has a half life of 10-12hrs. Won't adding Glut to fert solutions (that contain H2O, usually distilled water) mean that it is no longer effective after 24hrs or so in contact with water, thus rendering this style of dosing ineffective?
