We get asked all the time for details on our reef setup. Friends use the knowledge to help on their setups. This inadvertently leads to questions about water testing and the machines used for that purpose. We like the Hanna testers and have put out a video on the Phosphate vs Phosphorus Ultra Low Range Marine testers.
We are currently putting together a video on what tests we run weekly and the testers that we used to do that with. The recommendation is to test Alkalinity, Nitrite, Calcium and Phosphate (phosphorus). By this weekend it will be posted on the ReefDVMs Facebook page and on the ReefDVMs Youtube page.
