Brightwell Aquatics MicroBacter QuikCycl – Fishless Cycling Nutrient

Brightwell Aquatics MicroBacter QuikCycl – Fishless Cycling Nutrient

Kick off a clean, controlled nitrogen cycle—without risking livestock. MicroBacter QuikCycl provides precise ammonia-based nutrients forfishlesscycling when paired with a live bacterial culture such as MicroBacter Start XLM/XLF. 🧪🌊🐠❌

What It Does

• Feeds nitrifying bacteria with a clean, measured ammonia source
• Designed for both marine and freshwater aquariums
• Pairs with MicroBacter Start XLM/XLF for fast, reliable cycling
• Promotes a strong biological filter before fish are added

Important Safety & Setup Notes

• Fishless only:Do not use in aquariums containing live fish, corals/plants, or invertebrates.
• No media that removes nutrients:Donotuse carbon, GFO, or other phosphate removers until cycling is completeand30 more days have passed.
• Use test kits daily for pH, ammonia, nitrite (and nitrate when indicated).
• Have adequate bio‑surface area (e.g., rock, filter media). Turn off skimmer/UV and remove fine filter socks during the initial phase.

Full Day‑by‑Day Dosing Guide (Days 1–9+)

• Day 1
  • Turn off skimmer & UV; remove fine mechanical filtration (e.g., socks).
  • Dechlorinate (treat chloramine/chlorine), then set salinity, pH/alkalinity, and temperature.
  • Dose a full start of QuikCycl at4 drops per gallon(≈1 ml per 5 gal).
  • Test ammonia. Target is ~1–2 ppm total ammonia(NH₃ + NH₄⁺).Do not add moretoday even if your test reads low—the bacteria begin using it quickly.
  • Add live bacteria:MicroBacter Start XLM(marine) orXLF(freshwater) as directed.
• Day 2– Measure and recordpH, ammonia, nitrite.
• Day 3– Measure and recordpH, ammonia, nitrite.
• Day 4– MeasurepH, ammonia, nitrite. If either ammonia or nitrite is>0.25 ppm, youmayadd more bacteria (not more QuikCycl).
• Day 5– Measure and recordpH, ammonia, nitrite.
• Day 6– MeasurepH, ammonia, nitrite. If either is>0.25 ppm, youmayadd more bacteria (not more QuikCycl).
• Day 7
  • MeasurepH, ammonia, nitrite.
  • If you usedMicroBacter Start XLM/XLFand bothammonia = 0andnitrite = 0, then testnitrate.
  • Ifnitrate ≥ 0.25 ppm, the aquarium is consideredcycled.
  • If not yet at zero/≥0.25, continue to Day 8.
• Day 8– Measure and recordpH, ammonia, nitrite.
• Day 9 and subsequent days
  • Continue measuringpH, ammonia, nitrite.
  • Whenammonia + nitrite = 0, testnitrate. Ifnitrate ≥ 0.25 ppm, the aquarium iscycled.
  • At completion: perform a25% water change, thenslowlybegin adding hardy animals. Restart UV, skimmer, and mechanical filtration.

What’s Included

• 60 ml (2 oz) bottle of MicroBacter QuikCycl
• Dropper cap (≈ 20 drops = 1 ml)
