Brightwell Aquatics NanoCode B, 500 ml

Balanced Major, Minor, and Trace Element and Buffer System for Nano-Reef Aquaria

Purchase Part A Here



  • Part of a complete system for simplifying and maintaining proper water chemistry in very small (nano) reef aquaria
  • NanoCode B provides molecules that increase pH stability and form an integral part of aragonite, the mineral that is secreted by reef-building organisms
  • Used in conjunction with NanoCode A, promotes stable water chemistry and improves rate of biogenic aragonite formation
  • Contains no phosphate, silicate or organic material
  • Iodide in not present as it is unsuitable for indiscriminate dosing


Instructions and Guidelines

Basic: Shake bottle well before using. Add 5 ml (1 capful) of product per 10 US-gallons of aquarium water daily or as needed to maintain the alkalinity within a range of 7 - 12 dKH. When used in this fashion, 250 ml treats up to 500 US-gallons (1,893 L). When used in equal amounts with NanoCode A, the calcium and carbonates being added are in the same ratio found in natural seawater. Do not mix NanoCode A & B in the same container; this will cause the active components to precipitate and become ineffective. Allow 60 seconds to pass between dosing NanoCode

A & B.

Advanced: Determine the alkalinity in the aquarium using an accurate test kit before supplementing. Shake bottle well before each use. Each ml of Brightwell Aquatics NanoCode B will increase the alkalinity in 1 US-gallon (3.785 L) of water by approximately 1.67 dKH (0.60 meq/L). If the initial alkalinity in the aquarium is below 7 dKH (2.5 meq/L), add this product at the maximum rate of 5 ml per 10 US-gallons daily until the desired alkalinity is attained, then dose daily or weekly as needed (see below). Note that each aquarium has different requirements for calcium and carbonates (which largely constitute Alkalinity or Buffering Capacity, hence pH-stability); therefore, it is not uncommon for unequal amounts of NanoCode A & B to be required for obtaining and maintaining the desired calcium concentration and alkalinity. To determine the daily dosing rate for alkalinity maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in alkalinity by 1.67 (when measuring alkalinity by dKH; divide by 0.60 when measuring by meq/L); multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable alkalinity.

Caution: Contains carbonate and bicarbonate salts; harmful if swallowed. If swallowed: give water, get medical attention. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
