Ok, we'll go with that also. Y'all do quick to judge.Read this again even tho you say you do it.
- Make sure you are not rinsing your cuvettes with tap water ever, regardless of the test. This can lead to inaccurate readings from tap water contaminants.
- Make sure you rinse your phosphate cuvettes with RODI after each test before you store them. When you want to perform a new phosphate test we recommend rinsing the cuvettes with 10 ml of saltwater sample a few times before you zero out the Checker. This would help reduce the interference of contaminants that can impact your phosphate readings.
- Make sure you are not testing phosphates after cleaning algae in your aquarium or feeding your livestock. This will cause a false high reading.
- Make sure you are not using a syringe to fill your cuvettes that have been used to feed fish/coral as this will cause false high readings.
