Hey, running a kamoer x1 pro dosing all for reed 12 times a day only at 7.5ml in my 65 gallon system. I have the line taped tk my return hose just so it isn’t in the water, it’s about 1-2 inches off the water, but it is getting like a salt crust precipitate build up every other day when I check it. I cut the line at an angle and it still does it. What is causing this and how can I combat it so if I leave or don’t check it for a few days I know it’s still dosing?
