Gone are the days of jumbling test tubes when testing water quality in your aquaponic system. With our Test Tube Holder, your test tubes stand freely for easy reagent testing and color identification. With spaces for test tubes, a channel for the color chart, dry rack, and a gutter drain, our Test Tube Holder feels like having an extra pair of hands on the farm.

When testing water quality for your fish, there are four important parameters in aquaponics: pH, ammonia, nitrite, and nitrate. pH can also use a high range test. There are designated labeled spaces for each water quality parameter that aligns with its corresponding column on the color chart.

Test tubes, color chart, and water quality test kit sold separately.

Our Test Tube Holder is designed as an all-in-one tool. The test tubes stand freely upside down on the dry rack pegs. There are holes in the back gutter to allow for any water drainage. You can also store your caps atop the gutter.
