Secchi disks are the international standard for measuring phytoplankton abundance in the absence of turbidity. In short, secchi disks are used to measure the visibility of the water. Monitoring the visibility of your lake or pond provides valuable information, such as an oncoming plankton bloom. If you implement a fertilization program, monitoring your visibility is a must. The visibility of your water will tell you if a fertilizer application is needed or not.

Secchi disks are made of thick PVC, with an eye bolt holding the disk. Each disk comes with three feet of rope marked at 6" intervals for easy reading. You can add longer rope if you desire.
