I was trying to get some frogbit going in my 17 gallon planted betta tank, but I'm afraid Sir Henrick just doesn't poop enough to fertilize all the plants there. My poor frogbit was slowly starving. I saw that this fertilizer contained nitrates, which is the end game of the cycle of fish poop, and what plants crave. I added this "liquid fish poop", and within just a week, I had new growth on my frogbit. 6 weeks out from starting to fertilize with this, and my frogbit are looking better than ever, with many new leaves regularly popping out. Unless Sir Henrick suddenly grows an extra stomach and starts to poop more, I will be using this fertilizer regularly, and will definitely be buying it again.
