Fritz Aquatics PRO - F/2 Algae Food PTA - 16oz

A nice dense chemostat culture of Tetraselmis on this two part media. Running at f not f/2 concentration (i.e. twice as concentrated)

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.

I have been growing phytoplankton for years, and have used many fertilizers from proper f/2 formulations to miracle grow and miracid. I have had by in far the best luck with the widest variety of phytos using Fritz's f/2 formulation. Pro-tip; keep in fridge to keep possible bacteria contamination to a minimum.

I grow phytoplankton to feed my corals and decided to try this two part, I experimented with other brand F2 and the results are amazing, this yield a very concentrated deep green culture.

Doesn't grow my plankton like a regular F2, this one requieres a second component
