I guess it's working?
I have a 3 Gallon Aquarium for Blu my Betta. He has a few tank mates, a snail and aquatic frog. I decided to switch out the fake decor and make his environment more like he would have in the wild. So my black thumb self decided to add live plants to his aquarium. I know more than I did when I started and when I set up my 10 gallon I will use different substrate. I used gravel which has no nutrients for your plants to thrive in. I didn't know this. I don't overfeed my fish so they weren't getting much nutrients from that. So yes, they were not looking the healthiest. At the advice I obtained from FB groups I belong to, I started to treat with Flourish and CO2 boost, both bought here on Amazon. My plants have been looking healthier! I bought some frog bit and other plants from a seller here on Amazon and the plants arrived dead. Only a few (very very few) survived but were not in the best shape. This morning I'm seeing baby frog bits. yay. And some seeds I had planted which weren't growing have started to sprout! So I'm guessing this treatment is having a good effect on my plants. I recommend.
Thank you for your feedback

5.0 out of 5 stars Amazing for live plant aquariums
Reviewed in the United States on July 21, 2019
Am new to aquariums and learning as I go. Have had my tank for about 3 months now and found advice on how to set it up and keep it healthy very varying depending on whom you were talking to. But after getting my tank set up with water wanted to dress it up a bit before purchasing my fish to start the cycling. Thought live plants would be a great addition and also create a more true bio-system for my aquatic pets once they arrived. But my plants weren't doing well after the first week and found this online in several bulletin boards as the item to get to help them get the nutrients they needed without harming animals I put in my tank.

I have a 29 gallon tall tank purchased from a local box store, it came with everything I needed for a basic starting point to improve as I could afford to. I purchased 7 plants one of which died before ordering this product. My levels were out of whack, I check them once a week and as needed to keep track of what worked and what doesn't for me personally. But after using this product for one week noticed new growth, after two weeks the plants that were stressed and turning yellow in color have greened back up. Since have added 5 red eyed tetras and 3 albino cory cats to the tank and everyone is doing well. My numbers are safely within perimeters and it is beginning to look more and more like the tank of my dreams. I did develop a minor issue with black mold but did a total black out for 48 hours and added 5 mystery snails to clean what I missed after physically removing all I could. I also found this locally since then and plan on continuing to use it in future tanks and my current one.

Has proven safe for all creatures in my aquarium, makes my plants look and grow very well. Would recommend this to any novice aquarium keeper for a safe and easy solution. I add 1/2 a capful twice a week to my tank near my water filtration outlet to keep it in the water without overdosing the water. From everything I read it stays in the water for 24 hours. I only feed my fish every other day to minimize overfeeding and so far am loving my aquarium and regretting not trying this sooner. My previous experiences with having an aquarium have not done as well as this one. Am glad I kept trying and trusted in quality products to help me overcome any issues that have arisen.
