  • Enhances challenging pigments, especially yellow and orange.
  • Enhances red, pink, blue, and purple pigments, especially in Acropora corals.
  • Stimulates non-fluorescent chromoproteins for better pigmentation.
  • Designed for blue side spectrum light reef aquariums for better fluorescent proteins or reflective pigments excitation and stimulation.

  • 10ml x 100 liters will raise 2dKH.


  • Ready to use in 4-equal parts liquid.
  • Recommended to use with a dosing pump, especially for SPS dominant reef aquariums.
  • If your doser has only 3 heads, combine BASE-KH1 and BASE-KH2.

Tips for Accurate Dosing:

  • Ensure tubing from canisters to dosing pump heads has the same length.
  • Calibrate dosing pump as per manufacturer’s recommendation, checking every 6 months.
  • Set doser to dose equal parts with 10-15 minute intervals between each.
  • Spread the daily dosage as many times as your dosing pump allows per day.

Dosage Instructions:

  • Dose equal parts to keep KH between 6.8-8dKH.
  • For the first 2 weeks, find the ideal KH level based on calcium consumption:
    • If calcium decreases, raise dosage and keep KH higher, check calcium again.
    • If calcium increases, lower dosage and keep KH lower, check calcium again.
  • Once the ideal KH level is found, frequent calcium testing is not needed.


  • No need for additional products for coral coloration, polyp extensions, or growth.
  • Store product in a dark or shaded place, avoiding direct sunlight.
  • Preferable to use original canisters to avoid light exposure.
  • Does not require refrigeration but store in a cool place if needed.
