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

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.

Awesome!I had used this bottle first: https://www.amazon.com/dp/B0CFK2PHMH?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1It was mostly just water, my phyto was a light green water color. As soon as I switched to this the phyto turned a super beautiful dark solid thick emerald green.Awesome product! Fritz rocks.

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.

Great fertilizer. I am feeding my phytoplankton with this, part A and B. I have had no issues and it has been working perfectly.

Works well for phytoplankton culture.Use a s directed or your culture may crash.

Using this along with PTA and it has made a huge difference in growing phytoplankton. On the left is what grew using miracle gro, on the right is what grew using Fritz. I must say I’m pleased.Side note: I haven’t yet put the grown phyto in my tank after using this product so I’m not sure what additional effect it may or may not have on the tank. So far so good.

Ordered this to start culturing phyto. First one I received had the seal opened and smelled like sea water. I asked for a replacement.Next one I got was completely destroyed. Got another replacement.Third one I got yesterday looks like it was run over but the seal is intact. I will be testing it today to see if it actually works. Will update with pictures after.Update. 1 star. Third bottle is also not correct. Color in the bottle should be light pink and is instead clear, and likely used seawater. Never buying for this seller for any product again

didnt seem to do anything.
