FAQ
1: Will the smiley face design affect filtration efficiency?
Answer: No. The design uses precision laser-cutting to maintain uniform pore structure, ensuring optimal mechanical & biological filtration without compromising flow rates.
2: How long does the sponge last before needing replacement?
Answer: With proper maintenance (rinsing in tank water), our PU foam retains integrity for 12-18 months—outlasting standard sponges by 30% due to tear-resistant material.
3: Is the colored dye safe for sensitive aquatic life?
Answer: Yes. We use FDA-compliant, water-based dyes tested for 0 toxicity. Safe for shrimp, corals, and scaleless fish (e.g., loaches), with no leaching observed in pH 6-8.
