Brightwell Nano Code Part B 17 oz. (500 ml)
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 forms an integral part of aragonite, the mineral secreted by reef-building organisms.
Used in conjunction with NanoCode A, it promotes stable water chemistry and improves the rate of biogenic aragonite formation. Contains no phosphate, silicate, or organic material. Iodide is not included as it is unsuitable for indiscriminate dosing.

FAQ
What is the role of NanoCode B in a nano reef aquarium?
NanoCode B increases pH stability and contributes to the formation of aragonite, a mineral secreted by reef-building organisms. When used with NanoCode A, it supports stable water chemistry and enhances biogenic aragonite formation.
Does NanoCode B contain any harmful substances?
No, NanoCode B contains no phosphate, silicate, or organic material. Iodide is not included because it is unsuitable for indiscriminate dosing.
Can NanoCode B be used alone in the aquarium?
It is recommended to use NanoCode B in conjunction with NanoCode A for optimal results. Using it alone may not provide complete water chemistry support.

I’ve been using NanoCode B with NanoCode A for two months now. My nano reef has shown better pH stability and the coral growth seems more active. No signs of algae or phosphate buildup. Simple to dose and effective.

The product works well in maintaining stable water chemistry. I noticed a slight improvement in aragonite formation on the substrate. It’s easy to mix and store. Would recommend for small reef setups.

After switching to the NanoCode pair, my tank’s pH has stayed consistent even during water changes. No additives or impurities detected. Clear and reliable performance for a nano system.
