Tetraselmis Phytoplankton (16oz) Cultured

I purchase phytoplankton from algae barn and this is a better price and you can grow more to supplement your aquarium needs. it is a single species.

I don’t know exactly what’s inside the bottle but it’s very good

Great cultures as always. Keeping copepods and BBS well fed.

I bought a bottle of this a few months ago and used it to start my Tetra Phyto cultures. I can honestly say that this is by far the best phyto I have used to start a culture. I have tried a few single strains from larger companies to start my cultures and the phyto would settle heavily in the first day or two. For some reason, this culture stays suspended in the water column and I haven't had a single crash. I also harvest copepods and feed them this tetra phyto exclusively.

This juicy green elixir is probably the best you can ask for. I have ordered from a few other brands and let me just say Mercer gives you what you pay for. No thinned out phyto juice here, no sir... this is the real deal. no disappointments. 10/10 will order again. Thank you for a fine product.

I’ve used several and Mercer is a quality product

Never had a single issue, over several orders from these folks.

Excellent stuff.
