I'd love to see an alkalinity test pre/post application - giving it enough time to work and show up in the water test. Maybe part of me is from Missouri, but I have a hard time believing that 5 gallons of the stuff is equivalent to 2,000# of aggregate agricultural limestone.

Maybe they are talking about a different aggregate agricultural limestone, but the stuff I am thinking about is spread by a spreader truck and looks almost like powder.

Cody Note: I tend to agree with esshup. Not enough IMO good or correct pre and post testing were conducted by the users for the benefit of the owner and importantly the ecosystem which IMO is an injustice to the video and observer. I did not see dramatic changes nor significant improvements of test results for what IMO would have occurred with a correctly calculated aluminum sulfate treatment aka alum. . Calcis is a different active ingredient than Aluminum sulfate. Calcis is a liquified lime product and not an aluminum sulfate product. IMO Not saying the Calcis product is bad product it is just the good scientific limnological testing in the videos was lacking by the end users. Just one example - phosphorus both total and soluble were not pre and post tested. 2nd example - no turbidity tests. 3rd no TDS tests (total dissolved solids)
