Fritz F/2 Algae food two part.
For intensive algae culture in fresh or marine water.
Vitamin and mineral content ratios equal
Professional research concentration
Complete algae growth media
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.
All bottles are filled from 5 gallon buckets that we purchase.
8 ounce bottles do approximately 125 gallons of culture media.
16 ounce bottles do approximately 250 gallons of culture media.
32 ounce bottles do approximately 500 gallons of culture media
Gallon jugs are bottled from Fritz directly, these are meant for commercial applications and not hobbyist friendly. Gallon jugs are shipped via ground as 2nd day rates have increased
Approximately value is based on our recommendation of fertilizer per gallon. Fritz recommendation is 1 ml per 1 gallon.
*All bottles come with batch number and expiration date

Vendor leaves a lot to be desired. needs serious work on customer service skills. don't bother as other vendors sell the same stuff and have much better response when you have issues. Not worth the votes of my dollars anymore that's for sure
Hey Tom,
Not only did I answer your email, I took your phone call about questions on a Saturday. We talked, I asked you for a video on Saturday of your setup. You sent a video on Monday, a week that is absolutely crazy. Your emails are very demanding, I am sorry you had an issue with the feeding strains trying to culture them. Growing phytoplankton is not for everyone and it’s not my responsibility to give anyone advice on how to grow them. You want my time when it’s convenient for you and expect me to hold your hand. Have a great day and thanks for leaving a review!

Ordered the two part fritz f/2 with my culture order. Fast shipping and awesome customer service. My go to for live feeds now.
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!
