Tetraselmis Starter Culture Set - Live Phytoplankton & PhytoPheed Concentrated Guillard's Formula f/2 by Mercer of Montana

This is after culturing it /I use it for my feed my pod that I also culture worth the money just wish they had phyto only and not the kits

Very green and dense, very lively under the microscope and came with helpful instructions for starting cultures. Will definitely buy again.

Cultures came when they said they would. Packaged well. I noticed large particles in both bottles that did not dissolve with shaking. Since I am new to phytoplankton culturing I used them both anyway assuming it was just clumps of phyto. Day two both cultures crashed. Could it have been me? Sure. Maybe bad cultures, maybe. Hard to say. I am still using the fertilizer so I hope that's not where the contamination was because I used it on my new culture which is so far doing great. Fingers crossed.

Very dense product - much better than those folks from Colorado. Plus, this Montana boy likes to buy stuff from other Montanans

Already split culture and it was nice and dark green. This is going to save me a lot of money by culturing myself, which is super easy. Great product.

The phytoplankton was very clean and I was able to start a Tig copepods culture without any problems. The f/2 fertilizer that came in the package is very effective when starting up a new phytoplankton culture.

I have bought a few different phyto bottles over the year... this was the best by far.

Works great and comes at a great price!
