Using the trusted Guillard’s 1975 F/2 formula, it separates vitamins and trace elements into two stable solutions to ensure longevity and effectiveness.

## Description

Part a of a two-part growth medium for algae growth. Microalgae is an important food source for aquatic animals. Penaeid shrimp, fresh-water prawns, Artemia sp., Bivalve mollusks, etc., Have been successfully raised utilizing algae. Mass cultivation of microalgae requires a mixture of vitamins and minerals to supply nutrients for maximum growth. Our special formulation in two solutions (solution “a” and solution “b”), keeping separate vitamins from trace elements, allows for storage without the decomposition of vitamins or precipitation of trace elements. This pre-made formula allows the aqua culturist to devote time to culturing organisms, instead of agonizing over analytical balances. F/2 algae food supplies essential vitamins and minerals in a complete, easy to use liquid form in the concentrations according to Guillard’s 1975 f/2 formulation. F/2 algae food, used as directed, allows fast growth rate and high cell densities to be achieved.

## Questions & Answers

**Q: Is this good for chaetomorpha sp. and other brackish water microalgae?**
A: I use it to grow Nanochloropsis in brackish water.  I add 1/2 strength "Instant Ocean" salt to the final mix.  I also add sodium bicarbonate and sodium carbonate to improve growth.  Works well.

**Q: Can you mix part A and part B together in one container and store? Or do you have to keep both parts seperate?**
A: Keep em separate until you are actually using them or it forms a weird sludge.

**Q: Does this work for growing bioluminescent dinoflagellates?**
A: Along with  Part B to make the F/2 formula, yes it should help feed them.

**Q: Adding the 5ml of both parts to 10 gal of water, does that make ready to use water? or just the f2 that I then does my water with?**
A: I am dosing fresh made saltwater at 5ml per 10 gallons of a and b and then growing phytoplankton in that water. Hope that helps.

*by S***N on January 27, 2018*

Worked for growing the algae, but you have to guess how often to use it, as their are no instructions for this on the product label. I called and left a message with the company and am waiting on a reply to this question of how often to use the directed amount.

### ⭐⭐⭐ Creates Sludge after Mixing
*by M***6 on February 9, 2019*

When I mixed the two components together in equal amounts by volume, within 2 days I found a cloudy "goop" occupying the bottom 10% of the sterile glass container. I do not know if this is good or bad, but it looks terrible. I am using the part of the mixture without the sediment and it seems to be working okay, I am not sure if it is as effective as other sources of F2 I have bought in the past though. I do know those other sources did not drop out this ugly sediment. In the attached pictures, first shows immediately after mixing. Second shows 1 hour after mixing. Mixture was transferred from 500ml Lab flask to just emptied clean water bottle when first mixed.
