AquaBella Bio Enzyme eliminates water changes, chemical additives, and manual maintenance — delivered as a $24.95/mo Subscribe & Save or $29.95 single-bottle purchase on Shopify.
Prepared by Spot Marketing — May 2026
Ammonia and nitrates build continuously in closed systems, requiring constant manual dilution through labor-intensive water changes.
Synthetic salt, RODI water, pH adjusters, clarifiers, and chemical treatments. Reef owners spend significantly more.
The pet retail industry is optimized around selling recurring chemical fixes. A permanent biological solution threatens their model.
The paradox: AquaBella Bio Enzyme was too effective for retail — it eliminated the need for everything else. Retailers stopped stocking it. The DTC pivot bypasses them entirely.
AquaBella Bio Enzyme is the only consumer product that completes the full nitrogen cycle — aerobic nitrification and anaerobic denitrification — plus phosphate removal and organic sludge breakdown.

No competitor delivers the complete nitrogen cycle + phosphate removal in a single consumer product.
Seachem Stability (per their own product documentation) manages nitrates as part of the cycle but does not eliminate them[7]. AquaBella Bio Enzyme converts nitrate to harmless N₂ gas.

Lower per-bottle contribution offset by ~33 month avg lifespan → sub LTV = $215.
The free-shipping decision is the lever. Subs pay $4.95 less than one-time AND we absorb $6 shipping — a deliberate retention investment that compounds over 33 months of recurring purchase.
Per investor request: total customers separated from total subscribers. Each step shown for the Base Case ($216K Y1 marketing investment, $28 blended CAC).
Funds paid acquisition across FB/IG, Google, TikTok, and YouTube plus the Spot agency engagement.
Acquired across all channels at $28 blended CAC (Y1; improves 5%/yr).
25% of customers convert to Subscribe & Save. Remaining 75% are one-time buyers.
Monthly cohort acquisition + 3% monthly churn = ~85% of new subs active at year-end.

Blended AOV: $26.65 — lands inside the $24.95–$29.95 range investors requested.
One-time buyers deliver $19.11 contribution per order from the $38.90 all-in price. They're a profitable low-CAC discovery channel.
Subscribers deliver $6.46/mo contribution for ~33 months — after absorbing the $6 free-shipping cost. That's a $215 LTV — 11.3× the one-time customer.
A $28 CAC pays back in 4.3 months of subscriber revenue. Every subsequent month is pure margin.
12 bottles × $24.95
3% monthly churn[10]
LTV per subscriber
$215 sub LTV vs $28 Y1 blended CAC. 156% above the 3× VC benchmark[12].
$28 CAC ÷ $6.46/mo subscriber contribution. ~50% below the 12-month DTC threshold[12].
LTV formula: Subscriber contribution/bottle ($6.46 after free-ship absorption) × Avg lifespan (33.3 months at 3% monthly churn) = $215.43 per subscriber. Industry-standard formula used by Recurly, ChartMogul, ProfitWell.

Bull case uses the bottom-up channel CAC (Google $16, TikTok $20, FB/IG/YT $24 — weighted avg $20.27). Base case applies a 40% premium to that for Y1 ramp-up reality. Bear case models a soft channel ramp where blended efficiency lags target by 29%[11]. CAC improves 5%/yr in all scenarios as channels mature.
Adjust the drivers below to see how the model responds. Includes one-time + subscription revenue with the new cost structure ($6 COGS + 13% mgmt + 8% ops + 5% Spot). All outputs recalculate in real time.
| Year | Customers | New Subs | Revenue | Contrib | ROAS |

Monthly cohort model. One-time: 75% of customers × 1 bottle × $29.95. Subs: 25% × monthly bottles × $24.95 (incl. $6 free-ship absorption). Active subs ship 1 bottle/month. Monthly churn applied end-of-month. LTV = sub GP/bottle ÷ monthly churn.
Capital deployment funds Year 1 marketing at the recommended pace plus initial inventory, working capital, and runway buffer to bridge the Y1–Y2 contribution gap as the subscriber base compounds.
| Category | Amount | % of Raise |
|---|---|---|
| Year 1 Marketing (ads + Spot retainer) | $216,000 | 62% |
| Initial Inventory (12-month supply buffer) | $60,000 | 17% |
| Working Capital + Platform/Tech Setup | $50,000 | 14% |
| Contingency / Reserve | $24,000 | 7% |
| Total Raise | $350,000 | 100% |
Y2 onward self-funded by subscription revenue + 5% YoY marketing growth.
By Year 4, the recurring subscription engine alone covers marketing investment. Capital is needed to fund the customer acquisition runway through the Y1–Y3 J-curve.
At $28 blended CAC and $6.46/mo subscriber contribution, each subscriber pays back acquisition cost in under 6 months. Capital recycles into new acquisition quickly.
Bull case ($7.35M 5-yr revenue, $1.08M cumulative contribution) requires only that the channel-level CAC math holds. Base case is intentionally 33% more conservative.
A massive cultural shift is underway. Millions of aquarists are actively trying to build self-sustaining ecosystems.
Videos of aquariums running 500+ days without water changes accumulate millions of views on YouTube and TikTok.
30% of pet-owning households are Millennials — digitally native, subscription-ready, prefer eco-friendly solutions.
Crystal-clear water, zero effort. $24.95/mo replaces $500+/yr in chemicals.
Protect your $10K reef. Industrial-grade stability that eliminates coral-killing nitrates and phosphates.
Replace gallon jugs and the sulfur stench. 30ml replaces $2K/yr in maintenance.
18 years of industrial deployment across aquaculture, wastewater, and agricultural lagoons.
13M aquatic + 21.7M septic households. Less than 0.1% of SAM captured by Y5.
Only product delivering complete denitrification + phosphate removal in a 30ml format.
The product works. The market is real. The unit economics are disciplined and traceable.
$350K funds the customer acquisition runway. The subscription engine does the rest.
