Say Goodbye to Water-Change Anxiety: AC’s Patented Hollow Bio Beads—One Small Sphere that Unleashes a Self-Cleaning “Micro-Universe” in Your Tank
Update time: 25-09-22 Views: 54
“Weekly massive water changes, nitrite spikes, algae films everywhere…”
These headaches are almost a rite of passage for every aquarist.
At AC AquaClean Lab we believe one simple rule:
“Let bacteria work for us, not the other way around.”
After ten years of R&D—and a Chinese utility patent (ZL201220692481.3) granted in 2013—our Hollow Bio Beads were born.
Each 1 cm sphere hides an “under-sea volcano” that keeps your aquarium water pristine day after day.

1. The “Invisible Volcano” Inside Your Tank: Why a Deep Anaerobic Zone Matters
The nitrogen cycle doesn’t end at “zero nitrite”; it ends when nitrate is converted to harmless nitrogen gas.
Conventional biomedia only offer an aerobic biofilm 0.2 mm thick—anything deeper becomes stagnant.
The 3 mm hollow cavity inside every AC bead works like an inverted volcano:
- Outer macropores (>10 µm, negatively charged) → rapid colonization of aerobic nitrifiers (NH₄⁺→NO₂⁻→NO₃⁻).
- Inner nano-/micropores (0.2–2 µm, positively charged) → natural “low-oxygen zone” where anaerobic denitrifiers convert NO₃⁻→N₂ gas.
One bead, two ecosystems, full nitrogen removal—stretching water-change intervals from 7 days to 30 days or more.

2. A “Honeycomb City” Under the Electron Microscope
At 2 000× magnification you can see:
- A 10–50 µm “bay-window” lattice on the shell—negatively charged, letting nitrifying bacteria settle like building blocks.
- Inner walls with 200 nm–2 µm maze-like channels—positively charged, 1 500 m²/L specific surface, ready-made condos for denitrifiers.
- A 48 h “yellow-water” test showed 62 % TOC reduction and 3× clarity increase; coral fluorescence instantly looked one stop brighter.

3. Real-World Set-ups: From 60 cm Planted Tanks to 800 L Reef Systems
Planted tank
60 × 30 × 36 cm, neon tetras + Hemianthus callitrichoides
- Media: 1 L AC602L1-T (≈800 beads)
- Feeding: 1 g frozen bloodworms daily
- Results: NO₃⁻ 20 ppm → 5 ppm in 14 days; water changes weekly → monthly; staghorn algae down 90 %.
SPS reef
800 L, heavy SPS load
- Media: 4 L AC602L4-T in trickle tower
- Stock: 8 clownfish, 30 SPS frags
- Results: NO₃⁻ stable 0.5–1 ppm, PO₄³⁻ 0.02 ppm; Ca/Mg consumption rate –20 %; no water changes for 6 months, only top-off.

4. FAQs Every Hobbyist Asks
Q1. Will the beads crumble or dust?
Sintered at 1 200 °C, Mohs hardness 6.5; zero breakage after 50 rinse cycles.
Q2. Fresh and marine water safe?
pH & GH neutral; no leaching in high-Mg seawater; SGS RoHS & REACH certified.
Q3. How often do I clean them?
When flow drops ~20 %, gently swirl in old tank water—never tap water!
Service life ≥5 years, reusable and eco-friendly.

5. Three-Step “Painless” Upgrade for an Old Canister
1. Keep existing mechanical pads.
2. Replace ⅓ of old rings with Hollow Bio Beads every 10 days to avoid bacterial crashes.
3. From week 4 onward, test NO₃⁻ & PO₄³⁻; aim for NO₃⁻ <5 ppm and cut water changes accordingly.

6. Let Your Tank Return to “Display” Mode
AC Hollow Bio Beads are more than “filter media”—they’re a miniature sewage-treatment plant.
Hand the complex nitrogen cycle and organic breakdown to the beads, and give your time back to watching fish glide and corals glow under moonlight.
One less water change, one more moment of pure enjoyment—that’s the gift AC wants to share with aquarists worldwide.
