They Were Selling Unregistered Pesticides and Calling It Aquarium Cleaner
The Non-Financial Ledger: What Money Cannot Measure
Picture this. You have spent months building a reef tank. You have researched water chemistry, bought live coral frags, introduced fish slowly to let the ecosystem stabilize. Reef aquariums are not cheap hobbies. A single SPS coral frag can cost $50 to $400. A mature reef tank with lighting, filtration, and livestock can represent thousands of dollars of investment and hundreds of hours of careful, patient work. More than that, it is a living thing you are responsible for. These animals breathe, feed, and respond to their environment. Hobbyists form genuine attachments to these ecosystems.
Now imagine that a product marketed to you as an aquarium cleaner β something with a bright, clean brand name, something promising you a “sparkling, crystal clear, algae free, vibrant aquarium” β is actually an unregistered pesticide. You have no idea, because the label does not tell you. The label says 95% cultured bacteria blend. It says amino acids. It says vinegar. It does not say: contains GLB Algimycin 600, an EPA-registered algicide, the kind of active ingredient that requires federal registration before anyone can legally put it in a product and sell it to the public. You pour it into your tank because you trust the label. You trust that someone, somewhere, checked that this was safe for your fish, your corals, your invertebrates.
No one checked. The EPA did not check it, because Underwater Creations never asked them to. That is the entire point of the registration requirement β it is not a bureaucratic formality. It is the process through which the government reviews the ingredients, the intended use, and the safety profile of a pesticide before it enters the market. Underwater Creations skipped that entirely. They sold the products anyway. They sold Vibrant Reef 169 times. They sold Vibrant Saltwater 65 times. They sold Vibrant Freshwater 63 times. They sold Expel 22 times. They sold Purge 26 times. That is 345 documented transactions, plus 4 additional counted under the broader 349-violation total across all products, each one a person who trusted a label that misrepresented what they were buying.
People who buy reef products know the terror of a tank crash. When water chemistry goes wrong or an incompatible chemical gets introduced, entire tanks can die within hours. Corals bleach, fish suffocate, the biological filter collapses. Years of work and thousands of dollars can disappear in a day. If any of the buyers of these products experienced tank losses they could not explain, they had no way to connect the dots back to an unregistered pesticide, because there was nothing on the label to connect them to. They would have blamed themselves, blamed their water, blamed a sick fish. The harm is invisible and deniable, and that invisibility was baked into the product’s marketing from day one.
There is also something specific and infuriating about the Purge product. The 16-ounce label called it a “revolutionary in tank acropora eating flatworm destroyer.” Acropora corals are among the most delicate and sought-after specimens in the reef hobby. The people buying Purge were not casual consumers. They were dedicated reef keepers trying to protect high-value, hard-to-keep specimens from a specific parasite. They were exactly the kind of buyer who would follow dosing instructions carefully and trust the product’s claims completely. They deserved to know exactly what they were putting in their tanks. They were never told.
Legal Receipts: What the Documents Actually Say
The following quotes come directly from the EPA’s Consent Agreement and Final Order filed September 20, 2024, under Docket No. FIFRA-05-2024-0020. These are the government’s own words, based on the March 23, 2022 inspection by the Minnesota Department of Agriculture.
“Respondent’s Chief Executive Officer, Mr. Jeff Jacobson, informed MDA during the Inspection that Vibrant Reef, is made of a combination of Aspartic Acid, Bacteria Water/Culture, GLB Algimycin 600, and Water.”
- This is the CEO’s own statement to regulators, on the record, during the federal inspection. Jacobson confirmed that GLB Algimycin 600 β an EPA-registered pesticide β was an ingredient in Vibrant Reef, Vibrant Saltwater, and Vibrant Freshwater.
- The product labels sold to consumers did not list GLB Algimycin 600 by name. The labels listed “3.5% Other Ingredients” as the only disclosure covering this EPA-registered algicide. Consumers were never told there was a registered pesticide in the bottle.
- GLB Algimycin 600 carries EPA Registration Number 8959-37-7364. It is registered specifically to control algae growth. Underwater Creations used it, incorporated it into a consumer product, and sold that product without registering the finished product with the EPA as required.
“Respondent claimed, stated, or implied (by labeling or otherwise) that Vibrant Reef can or should be used as a pesticide. Therefore, Vibrant Reef is intended for a pesticidal purpose as provided in 40 C.F.R. Β§ 152.15(a)(1).”
- This is the EPA’s formal legal finding. The agency is stating that Underwater Creations’ own marketing language β “say goodbye to algae” β constitutes a pesticidal claim that triggers mandatory federal registration requirements.
- The company cannot argue they did not know the product was a pesticide. Their own label made the pesticidal claim. Their own CEO confirmed the pesticidal ingredient. The EPA also found that the company had “actual or constructive knowledge” that all five products would be used for pesticidal purposes under 40 C.F.R. Β§ 152.15(c).
“PURGE is a new revolutionary in tank acropora eating flatworm destroyer. PURGE will flush your system of unwanted coral pest.”
- This is the actual label text collected by MDA inspectors from 16-ounce containers of Purge. The company marketed this product with explicit pest-destruction language directly on the packaging β one of the clearest possible indicators of pesticide intent under FIFRA.
- Purge was distributed or sold on at least 26 separate occasions between March 18 and December 7, 2021. Every one of those 26 sales constitutes a separate FIFRA violation.
- The 8-ounce label also claimed the product “safely removes pests from aquarium corals.” The word “safely” carries particular weight: it implies a safety evaluation occurred. No such evaluation by a federal regulator had taken place, because the product was never registered.
“Between February 9, 2021 and February 15, 2022, Respondent distributed or sold Vibrant Reef on at least 169 separate occasions… Each of Respondent’s distributions or sales of the unregistered pesticide Vibrant Reef constitutes a separate unlawful act.”
- The phrase “at least” matters here. The EPA counted 169 violations for Vibrant Reef alone based on distribution and production records collected at inspection. The actual number of transactions may be higher.
- Federal law treats each individual sale as its own violation. The maximum civil penalty per violation under FIFRA at the time of assessment was $24,255. Even at a small fraction of that maximum, the scale of liability was enormous β which explains how a small Minnesota aquarium company ended up facing $226,652 in penalties.
What You Were Told vs. What Was Hidden
The gap between the product labels and the regulatory reality is the core of this case. Here is the documented contrast, drawn directly from the EPA enforcement document.
Anatomy of the Label: What Was Disclosed vs. What Was Inside
The label on every bottle of the Vibrant line presented a simple, consumer-friendly ingredient breakdown. What the CEO disclosed to federal regulators during inspection tells a very different story about what was actually in the product.
The Timeline: From First Sale to Final Order
The documented sales window, inspection, and regulatory resolution spans nearly four years. Here is the sequence that matters.
Societal Impact Mapping
Public Health
The registration process under FIFRA exists specifically to protect people and environments from pesticides that have not been reviewed for safety. Skipping it has documented categories of consequence.
- Products containing GLB Algimycin 600 were being sold directly to consumers for use inside enclosed home aquarium environments, without any federal safety review of the finished product’s formulation, dosage, or exposure risks. Handlers were not informed they were working with a product containing a registered pesticide.
- The labels’ assertion that Purge and Expel “safely remove pests” was an unsupported marketing claim, not a regulatory certification. No EPA safety review had taken place. Consumers had no way to know whether the product was safe for their fish, their corals, their invertebrates, or themselves during handling and dosing.
- Aquarium hobbyists, including children who assist with tank maintenance, were exposed to an unregistered pesticide formulation without warning language, protective equipment recommendations, or safety data sheets required by the registration process. First responders dealing with accidental ingestion or contact had no registered product data to reference.
- The EPA’s FIFRA registration process requires applicants to submit safety data, efficacy tests, and environmental fate studies before a product can be sold. Underwater Creations bypassed this entire review, meaning no independent scientific body ever evaluated whether their specific formulation was safe for the intended aquarium use case.
Economic Inequality
The structure of this case reflects how the regulatory gap hits ordinary consumers hardest while corporate accountability comes late, cheap, and consequence-free for the buyers.
- The $226,652 penalty covers 349 documented violations. That works out to roughly $650 per violation. The maximum civil penalty per FIFRA violation was $24,255 at the time of assessment. The company paid less than 3 cents on the dollar of the maximum statutory exposure β a discount of over 97%.
- Consumers who purchased these products received no restitution under the terms of the settlement. The consent agreement resolves only federal civil penalties. There is no provision for compensating buyers whose tanks, fish, or corals may have been harmed by an unregistered pesticide they were told was safe.
- Reef aquarium hobbyists are a spending-intensive consumer demographic. A single SPS coral frag, the exact type that Purge was marketed to protect from flatworms, can cost $50 to several hundred dollars. Consumers trusted Purge’s claims and paid for protection they had no way to verify was scientifically validated. If their tanks were damaged, they absorbed those costs alone.
- Small-business competition in the aquarium product market is real. Companies that go through proper FIFRA registration incur significant costs in testing, documentation, and EPA application fees. Underwater Creations avoided all of those costs, gaining an unlawful competitive advantage over compliant companies while passing the risk of unreviewed pesticide exposure to consumers.
- Underwater Creations is described in the CAFO as a corporation doing business in Minnesota. The penalty terms explicitly allow the EPA to refer collection to the IRS, credit agencies, or the DOJ if unpaid. There is no indication in the source document that any punitive outcome beyond the civil penalty was pursued, and the company waived its right to any hearing that might have surfaced the full scope of consumer harm.
The Cost of Compliance: What the Penalty Actually Means
Numbers without context are just numbers. Here is the context.
How It Was Supposed to Work: Compliance vs. What Actually Happened
Under FIFRA, the path from “we have a product that kills algae” to “we can legally sell it” has mandatory federal checkpoints. Here is the gap between what was required and what Underwater Creations did.
What Now? Who to Pressure and How to Push Back
The consent agreement is final. The penalty is paid, or will be. But the systemic conditions that allowed this to happen remain. Here is who has ongoing authority and what you can do.
The People Who Signed Off
- Jeff Jacobson: CEO of Underwater Creations, Inc. His name appears in the federal document as the individual who personally disclosed the product formulations to MDA inspectors. He is on record confirming the presence of GLB Algimycin 600 in products whose labels never named it.
- Michael D. Harris: Director, Enforcement and Compliance Assurance Division, EPA Region 5. The complainant of record who signed the consent agreement on September 18, 2024. His division determined that $226,652 was “appropriate” for 349 violations.
- Ann L. Coyle: Regional Judicial Officer, EPA Region 5. She issued the final order on September 19, 2024, concluding the proceeding. Her office is the final authority on this case within the EPA’s regional structure.
Watchlist: Regulatory Bodies With Ongoing Jurisdiction
- EPA Region 5 / Pesticides and Toxics Compliance Section: Primary federal enforcement authority under FIFRA. Contact: Emma Gloekler, Gloekler.Emma@epa.gov, as listed in the CAFO. File complaints about unlabeled or unregistered pesticides through EPA’s enforcement tip line.
- Minnesota Department of Agriculture (MDA): Conducted the March 23, 2022 inspection that triggered this case. Has state-level authority to monitor pesticide distribution within Minnesota and can initiate independent enforcement actions beyond the federal CAFO.
- EPA Office of Pesticide Programs (OPP): Manages the federal FIFRA registration database. You can search their pesticide product database to verify whether any aquarium product you purchase carries a valid EPA registration number before you use it.
- FTC Bureau of Consumer Protection: Has jurisdiction over deceptive marketing claims. The word “safely” on an unregistered pesticide label with no safety review is exactly the kind of unsubstantiated product claim the FTC can investigate separately from EPA enforcement.
What You Can Do Right Now
- Search the EPA’s pesticide product database (epa.gov/pesticide-registration/find-registered-pesticide-product) before adding any aquarium treatment product to your tank. A legitimate registered pesticide will have an EPA Registration Number printed on the label. No number, no registration.
- If you purchased any of the Vibrant Aquarium Cleaner products, Expel (Coral Cleanse), or Purge V2 from Underwater Creations, document your purchase and contact the Minnesota Department of Agriculture’s Pesticide and Fertilizer Management Division. State regulators can receive consumer complaints independently of the federal settlement.
- Connect with reef aquarium hobbyist communities β both online forums and local reef clubs β to share knowledge about FIFRA requirements and how to verify that products marketed for aquarium pest control are legally registered. The people most vulnerable to this kind of labeling misconduct are passionate hobbyists who trust product claims implicitly.
- Support organizations that advocate for stronger FIFRA penalty enforcement, including higher base penalties per violation to eliminate the economic advantage of regulatory non-compliance. At $650 per violation, the current settlement offers minimal deterrence to a company that saved money by skipping the registration process entirely.
- If you run or participate in a local aquarium society, ask vendors and suppliers at trade events to show EPA registration numbers for any product marketed to control pests, algae, parasites, or bacteria. Normalizeing that request creates accountability at the point of sale.
