pH Crash Nightmare? AC Alkali 3D Filter Media Brings Cichlids, Plants & Reefs Back to Safety in One Go!
Update time: 25-10-16 Views: 1
“Last night the arowana was still eating like a pig; this morning it’s clamping fins and rubbing against the glass.”
“Fresh leaves on my stems are yellowing, ADA soil is exhausted, and the pH is dropping to 5.0!”
If you have ever posted a cry-for-help thread like this, you have already stepped on the invisible land-mine called pH crash.
1. Why is a pH crash so deadly?
- Ideal range: 6.5-7.5 for freshwater, 8.0-8.3 for marine.
- When pH stays below 6.0 for >48 h:
– The NH₃/NH₄⁺ balance shifts; gill toxicity soars.
– Nitrifiers stall, nitrite spikes.
– Plants stop pearling, SPS corals halt calcification.
2. Why do traditional “quick fixes” fail?
- Baking-soda: roller-coaster pH, KH swings.
- Massive water changes: labor-intensive and tap/RO water is often acidic.
- Crushed coral: bulky, ruins aquascape.
3. AC Alkali 3D Filter Media – “3-D pores + alkaline core”
Our R&D team merged buffer chemistry with biological filtration in one reusable product.
A. Continuous 3-D pore lattice
One litre of media = ~1,800 m² surface, equal to four basketball courts. Billions of nitrifiers and denitrifiers settle in layers, converting ammonia→nitrite→nitrate without clogging.
B. Micro-tunnel slow-release base
When pH ≤ 6.5, trace mineral hydroxides and carbonates dissolve, releasing OH⁻ & HCO₃⁻ to pull pH back to 7.0-7.8. Release stops at pH ≥ 8.0—no over-shoot.
C. Non-powdering, TDS-friendly
90-day tumbler test: breakage <0.3%. KH rises 2-3 dH, GH almost unchanged—safe for crystal shrimp and discus.
4. Real-world results
- 120 L planted arowana tank, ADA soil 14 months old, pH 5.08. Replaced ⅓ of old media with AC Alkali 3D Filter Media; pH stable at 7.2 after 72 h, NH₄⁺/NO₂⁻ = 0 mg L⁻¹, fish resumed feeding.
- 400 L SPS reef, Ca-reactor effluent pH 7.7. Added 4 L AC media as post-reactor stage; pH 8.2 within 6 h, better polyp extension and colouration.
5. Usage tips
1. Rinse with tank water—no boiling!
2. 1 L treats ~200 L; double dosage for severe crashes.
3. Stack order: mechanical floss → AC media → conventional rings.
4. After 12 months replace 50 % if pH buffering weakens (test kit shows <6.5 again).
pH crashes don’t happen overnight, and they won’t disappear overnight either. Give your fish, shrimp and corals a breathable, self-buffering bodyguard—AC Alkali 3D Filter Media—and let them thrive in the stable pH they deserve.
