Markp2483 Posted May 15, 2021 Share Posted May 15, 2021 Would love a aquarium plant specific test strip. They make them for soil but not aquarium water. It’s easy to find test for nitrogen ( nitrate) and phosphate but not potassium. Really enjoying the new aquarium coop strips but adding something for plants would be amazing.

StephenP2003 Posted May 15, 2021 Share Posted May 15, 2021 Does an accurate test strip for potassium exist? I have a liquid potassium test that uses three reagents, and apparently it's really sensitive. Link to comment Share on other sites More sharing options...

CT_ Posted May 15, 2021 Share Posted May 15, 2021 I may be way off here but I think potassium is one of the macros that you can have in excess and it won't cause problems. It doesn't solve the strip problem but maybe its less necessary. Link to comment Share on other sites More sharing options...
