Received my order very fast and was packaged. Nice nicely.
Love the rhodo culture. Two very dark harvests so far. Pods and rotifers love it. NPS and sponges seem to be responding well too.

Shake well before using, our recommended dosing for concentrated phytoplankton cultures is 2ml of each part per 1 gallon of phytoplankton culture. Do not mix parts together as this will cause cloudy cultures, only add both parts once you're ready, add each measurement at different times to the culture.
This product does not contain silicate, a required nutrient for diatom phytoplankton cultures, please add our silicate mix separately.

Great fertilizer with great results
First order and came in safe and well packaged!
I spoke to Skyler about a good beginner's phyto. He recommended chlorella and tetra strains fed with Fritz 2 part. I'd gone with two different strains and f2 from another supplier previously and didn't fare too well. So far, I've done two harvests using the Fritz 2-part and am currently growing out my third harvest. Very good results!

Reef Legends is the real deal. Not sure where to start, honestly. Deep knowledge, high-quality cultures, and real support when it comes to phytoplankton. The guidance and consultations alone were worth it. Huge thanks for the quality and the help 👍
Magnificent phytoplankton, super green, and all the pods arrived alive.Thank you for the candies.
Just wanted to say thanks for all the help and support getting my first culture started! Great customer service and support! I probably would have failed several times starting out on my own.
I’ll definitely be a customer for a long time.
2nd time ordering from these guys and every batch have been great! The price, packaging and speed of delivery will not disappoint
After two failed attempts to culture R. Salina, I had given up. After watching Skyler's video, I mustered up the courage to try again. He explained there is a difference between phyto for feeding and phyto for culturing. I followed his procedure, and 9 days later I harvested. 1.5 quarts. The extra steps I took to sanitize everything, and to sterilize the media made a big difference. Thank you, Skyler!!!
