Give Your Aquarium "Air-like" Filtration – AC Super Bio Foam Stone, the Magic Media That Lets Koi Ponds Breathe

> Crystal-clear water and vibrant fish are the ultimate dream of every aquarist, yet ammonia, nitrite and cloudy water can feel like a never-ending nightmare. In the AC AquaClean lab we heat glass to over 900 °C until it becomes "airy" – a breathing stone called Super Bio Foam Stone. It is so light that it almost floats, yet offers bacteria ten times more "mansions" than ordinary ceramic media and gets the water column "running" by itself.

 

 

1. Why Conventional Media Often Fail

1. Ceramic rings or lava rock carry isolated pores; bacteria settle "in the suburbs", colonies slough off during cleaning and clogging follows.  

2. Heavy weight stresses multi-bay, trickle and overhead filters; maintenance feels like moving bricks.  

3. Small surface area means a low bacterial ceiling – any ammonia spike breaks through the system.

 

 

2. The "Air-like" Tech Inside AC Foam Stone

Parameter	Traditional Ring	AC Foam Stone
Specific surface	≈600 m²/m³	≥6,000 m²/m³
Bulk density	850 kg/m³	180 kg/m³
Pore type	Isolated	3-D interconnected micro-tunnels
Crumble rate	5-8 %	<0.5 %
Service life	1-2 yrs	5 yrs+

  
 

Molten glass is foamed into a honey-comb of micro-tunnels – every cubic centimetre looks like a city ring-road. Nitrifiers, denitrifiers and mineralisers live in layers, completing nitrification→denitrification→mineralisation in one pass, removing ammonia, nitrite and nitrate while stabilising pH and GH.

 

 

3. Real Case: From Cloudy to Crystal in One Week

8-ton koi pond, Guangzhou, heavy feeding, TDS 900+, surface foam persisted.  

Retrofit:  

- Replaced 80 L ceramic rings with 30 L AC Foam Stone (53 kg lighter)  

- Trickle tower: 1st bay floss, 2nd & 3rd Foam Stone, 4th AC FAR-IR bacteria house  

   

Result:  

- Day 3 – surface foam −70 %  

- Day 7 – NH₃ 0 → 0.01 mg/L, NO₂⁻ 0.3 → 0.02 mg/L, visibility 10 cm → 60 cm  

- Maintenance: stop pump once a month, swirl in pond water 10 s – debris released, bio-film stays anchored.

 

 

4. Top 3 Questions Hobbyists Ask

1. "So light – will it tumble?"  

   Water-logged weight increases only 1.2×; stays put in trickle, shower, moving-bed or Bakki showers.

 

2. "Does it need curing?"  

   Sterile from 900 °C firing; rinse with tap water and use. Speed up by soaking 2 h in AC nitrifying bacteria activator.

 

3. "How often to replace?"  

   Glass backbone resists corrosion; compressive strength loss <5 % after 5 years – buy once, last for "fish generations".

5. Pro Tips

- New tank start-up: 3 L Foam Stone + 1 L FAR-IR bacteria house per 1 t water; cycle completes in 14 days.  

- Old system upgrade: replace 1/3 of old media first, monitor water parameters for a week, then continue to avoid bacterial crash.  

- Works in marine or African cichlid tanks; micro-tunnels buffer sudden KH drops.
