The System

A system,
not a supplement.

Reusable bottle. Powder refill. Dosing pump ready. Buy the hardware once. Refill the chemistry forever.

THE WORKFLOW

Three steps,
once a month.

01

Step One

Tear open the pouch.

117 grams of certified-grade powder, dose-calibrated for V5.9 spec. No measuring cups, no chemistry math. Drop it in.

02

Step Two

Add 1L of RO/DI water.

From your own RO/DI line. Cap, shake until dissolved. The fill line on the BioForge bottle tells you when you're there.

03

Step Three

Connect your dosing pump.

4mm barb fitting on the cap. Works with Kamoer, Neptune DOS, Reef Octopus — every standard reef dosing pump. The bottle is the reservoir.

THE HARDWARE

BioForge Core+ Alkalinity — powder pouring into bottle

The bottle is the product.

Most reef supplements ship in disposable plastic. We engineered a reusable HDPE bottle with an integrated dosing barb. You buy it once.

  • 01
    Integrated 4mm barb

    Direct line to your dosing pump. No transfer container.

  • 02
    Wide-mouth packet drop

    Tear, pour, fill. No funnel required.

  • 03
    Tamper-evident ring

    New ring with every refill. Factory-fresh, every time.

  • 04
    Color-coded by chemistry

    Red ALK, green CAL, blue MAG, white KalkPure. Visible at a glance.

THE FORMULATION

Forgives a missed water change.

Most reef chemistry brands choose a side: simple 2-part for affordability, or full three-part Balling for ionic balance. Both have trade-offs. Pure 2-part accumulates sodium and chloride faster than water changes can remove. Three-part Balling is operationally complex.

BioForge Core+ ALK takes a middle path. Sodium carbonate handles the alkalinity. Sodium sulfate, potassium bicarbonate, and borax handle the ionic balance — slowing the long-term drift that 2-part systems normally fight against. The result is a formulation that doesn't punish you when life gets in the way of your water change schedule.

We still recommend regular water changes. The chemistry is designed to forgive a missed one — not replace them.

THE ECONOMICS

Hardware once.
Refills forever.

$69
Starter kit · 3 chemistries, 3 reusable bottles, beaker, dosing adapter · ships once
~$21/mo
Refill packets · sized to your tank's actual consumption · cancel anytime
117–149g
Refill packet net weight · ships flat in foil · no bulk plastic

A standard reef supplement bottle is mostly water you're paying to ship. A BioForge refill is the powder, dosed, in a flat foil packet. Hardware once. Powder forever.

Ready when
Phase 1 ships.

Launch is targeted Summer 2026. Waitlist gets launch-day pricing and first access to beta slots.
