A clear plan for your pond, built on real measurements.
We mail you a kit. You sample from the bank in about 20 minutes, including a throw sampler that pulls up the bottom from out in the pond. Our lab runs 14 measurements on your water, the bottom and the algae, and a scientist calls you with a ranked plan and the reasons behind it. No site visit.

What you get back: a plan, not a printout.
- Your plan, on a map of your pondEach step with who does it, what it costs, what it buys, and a button to connect with local vendors.
- Your options, comparedEvery fix and combination we modeled for your pond: what it costs, and how much it cuts your algae.
- Why this planWhat's feeding the bloom, step by step, and how sure we are.
- Three lines of evidenceYour satellite history, this year's weather, and your lab results, side by side.
- What's driving it, rankedThe bottom, runoff, fertilizer: how much each one matters.
- Every resultEach measurement against the healthy range for ponds like yours, flagged like a medical lab report.
Kits ship to the 50 U.S. states, Puerto Rico, the U.S. Virgin Islands and the Caribbean, and come back by prepaid USPS Priority Mail Express. The toxin test (microcystin, anatoxin, cylindrospermopsin) is freshwater only.
What's in the box
Everything you need, labeled.
Every bottle and tube carries your kit number. Add the date, time and your initials, tick the collection sheet, freeze, and send it back in the prepaid envelope.
- Six labeled water bottles: A1/A2, B1/B2, C1/C2Each in duplicate, so one contaminated bottle doesn't cost you the test. A: unfiltered, frozen — total nutrients. B: filtered, frozen — dissolved nutrients. C: chilled, never frozen — pH, salinity, alkalinity, turbidity and algae ID
- Three labeled 50 mL sediment tubes: S1, S2, S3One tube per throw, kept separate (no mixing), frozen
- Flat-pack throw sampler + 30 m line on a winderYours to keepFive flat plates that slot together by hand in about 2 minutes (tab-and-slot, two wing nuts, clip-on weight bars), with eye bolts and snap clips for the bridle. Identical top and bottom, so it works whichever way it lands
- 60 mL Luer-lock syringe (no needle)Pushes pond water through the filters
- Four disposable 0.45 µm syringe filtersTwist onto the syringe tip to fill B1 and B2 — two spares in case one clogs
- Two pre-loaded chlorophyll filter holders (F1, F2) with capsDisposable 25 mm holders with a glass-fiber filter inside: push 50 mL through, cap both ends, freeze the whole holder — no loose filter discs to handle
- Two fine-tip permanent markersFor the date, time and initials on every label and the collection sheet
- Sample collection sheetOne page: your name, address, the kit ID, and a checkbox for each sample
- Nitrile glovesBare hands would spike your own results
- Weighted Secchi disk on a marked lineYours to keepOptional: read clarity straight down from a dock or boat
- Marked thermometerYours to keepSurface temperature
- Insulated pouch, gel ice pack, bottle sleeve + leak-proof bagKeeps your samples cold on the way back; the sleeve keeps the C bottles from freezing
- Prepaid USPS Priority Mail Express envelopeDrop at any post office or blue USPS box, or book a free pickup
- Illustrated sampling guideStep by step, about 20 minutes at the water
Toxin test add-on, +$89: microcystin, anatoxin, cylindrospermopsin (freshwater only). Samples are analyzed using standard EPA and APHA (Standard Methods) procedures with documented detection limits and uncertainty. Our lab is not NELAP-accredited; results are for diagnosis and management decisions, not regulatory compliance reporting. If you need certified results for a permit, tell us and we'll route your samples to an accredited lab at cost.
How to order
Call or email to order.
For now every order goes through a scientist first, so nothing is charged online. $179 one-time, or $299/yr with one extra checkup (two a year) plus satellite watch and alerts. Add the toxin test for +$89 (freshwater only).
Not ready yet? The free read can also email you a free monthly satellite check on your water, so you see when it starts to turn. When it does, the $299/yr plan is what finds out why: lab checkups of the water and the bottom, and a scientist's plan.
