A single-use field screen for microcystins and nodularins, the liver toxins most often produced by blue-green algae (cyanobacteria). Collect a sample at the shoreline, run the test, and read the cassette on site in about twenty minutes.
A bloom tells you algae are present. It does not tell you whether toxin is. This test answers that question where the water is used, so a lake community can decide whether to post a caution at a beach or boat launch today rather than after a lab report comes back.
It is a screen, not a certified result. A positive should be confirmed by laboratory analysis before it drives a formal advisory.
Results on site, about twenty minutes from sample to reading.
We will never say we handle the science for you. A method you can see is one you can check, repeat, and defend. Lake Pulse sells measurement, not treatment — what you buy here positions you to solve the problem, and to prove whether it worked.
Results from this product land in your lake's shared record in the Portal — next to everything else your lake has ever measured, instead of in an inbox.
