## Overview

Mercer of Montana’s 16oz Nannochloropsis Phytoplankton is a premium, lab-cultured microalgae designed for reef aquarists and marine invertebrate enthusiasts. Cultured under sterile conditions with industry-standard nutrients and optimal salinity, it delivers high-density, vitamin-rich live phytoplankton that promotes vibrant coral and healthy filter feeders. Refrigeration extends its viability up to 30 days, making it a reliable, potent choice for propagation or direct feeding.

## Description

Your purchase of Live Phytoplankton includes one 16 ounce plastic bottle. Nannochloropsis is a beneficial microalgae found throughout the world’s oceans. This live phytoplankton has been cultured from a pure sample cultured in agar, using the industry-standard Guiliard f/2 formula fertilizer to promote exponential growth, high nutrient retention, and longer viability. The genus Nannochloropsis is widely accepted as the standard of reef keeping aquarists, to promote growth and vibrancy of corals, invertebrates, and other livestock. This live phytoplankton may be used as an inoculant to propagate additional quantities, if desired. We adhere to the highest standards of sterile laboratory protocols, to ensure that each bottle of dense, vitamin rich Phytoplankton is contaminant-free. Our phytoplankton is cultured using saltwater made from reverse osmosis deionized resin (RODI) water and Instant Ocean saltwater mix, at a salinity of 1.020 sg. Directions: To obtain best results, we suggest the daily addition of 3-4ml to every 100 gallons of saltwater in your system, pouring directly into the display tank, or associated sump. This phytoplankton may be fed to your livestock directly, in order to target specific recipients, if desired. Storage: To extend the viability of the contents past the 7-day growth cycle, remember to refrigerate contents immediately upon receipt and invert bottle once daily. In this manner, contents should retain potency for up to 30 days. Phytoplankton to be used as an inoculant should be used within 7 days of receipt, to assure maximum density.

Review: Very good - Great phyto. Very concentrated compared to other live phyto. Cultured fast.
Review: High quality Phyto - I have purchased from Mercer several times now and have always received top quality Phyto. I have had a reef aquarium for over 20 years and until recently have purchased Phyto from several other online sellers . I bounced around from seller to seller because of the unreliability of the various vendors poor quality Phyto cultures . I am elated having found Mercers . Mercers cultures are always rich and viable. I use the to produce my own cultures at home and have never had a problem growing out Mercers culture. I believe it is of the highest quality Phyto available at the moment.

## Questions & Answers

**Q: When opening the bottle it has a funny smell to it just wondering if that’s normal for it to have a weird odor?**
A: I’m pretty sure that’s normal, but if the color is way off and it smells REALLY foul it may have died in transit.. I would just keep an eye on it the next few days, I’d it turns browner it’s probably dead

### ⭐⭐⭐⭐⭐ Good product.
*by J***M on March 13, 2024*

Packed well. No smell & fresh. Must shakes the bottle 1-2 days, whether use or not. Keep refrigerator and will last longer. Don't over dose, will increase NO3 & PO4. Always dose less than what requires.
