Great aquarium supplement
I was struggling to keep my aquarium plants alive so I started looking for supplements that could help. I read a lot of reviews that said this product was extremely helpful in keeping plants alive so I decided to give it a try and I was extremely pleased with the progress of my plants. My plants have been flourishing since I started using this and id recommend it if you think your plants need some added support.

Highly Recommended – Plants and Fish Thrive!
I’ve used Seachem Flourish Freshwater Plant Supplement (500ml) before, and it’s always my go-to. A local store with beautiful plants and a great quarantine process for fish highly recommended it, and I can see why. Pros: - Keeps plants thriving and continuously growing. - Works for all types of aquatic plants - Doesn’t require large doses depending on tank size Cons: - Needs to be refrigerated Since using this, my tank has become even more beautiful—lush, green, and full of life. My fish thrive in a well-planted environment with plenty of hiding spaces, making them more active and comfortable. I also have a separate tank for growing plants, which I sell to a store while quarantining fish before adding them to my main tank. This supplement has been essential in keeping both my plants and fish healthy. Would I buy it again? Absolutely.

Great product, but copper kills shrimp
Great for plant growth. Most Seachem products are awesome AF. Use carefully. Overuse can cause iron buildup in substrate, then collapse of bacterial flora. Even conservative dosing is lethal to caradinia (including amanos) & neocaradinia shrimp. At $6 each and a minimum population of 10-15 shrimp, that's an expensive mistake ($60-$90 + sales tax!). Please consider prominently writing "not for shrimp tanks" in product descriptions & on product label.

Does What It's Supposed To
This fertilizer is pretty much what you'd expect from a plant supplement - it adds nutrients to your tank so your plants can thrive. The instructions are straightforward enough, though I did have some trouble figuring out which cap thread was which at first (I guess they all look the same when you're tired). Anyway, I followed the recommended dosage and my plants seem to be doing well. One thing I noticed is that it makes the water a bit cloudy initially, but that cleared up after a few hours. Not sure if that's normal or not, but it didn't cause any issues (kind of like when I spilled coffee on my keyboard once - everything still worked fine). All in all, Flourish is a solid choice for keeping your plants healthy and happy. It's easy to use and does its job well, so no complaints here.

Amazing for live plant aquariums
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.

Truly Easy to Use
I recently started using Seachem Flourish in my planted aquarium, and I'm really impressed with the results. This product is packed with a broad range of essential micronutrients, which has made a noticeable difference in the health and growth of my plants. Before using Flourish, I had some issues with slow growth and yellowing leaves, but those problems have significantly improved. The dosing is straightforward, and the solution mixes well with my tank water without causing any cloudiness. I've found that it really helps in keeping my plants vibrant and lush, which adds to the overall beauty of the aquarium. One thing to note is that it’s designed for tanks with a good amount of light and CO2 supplementation, so make sure your setup is compatible to get the best results. Overall, I’m very satisfied with Seachem Flourish. It’s become a staple in my aquarium maintenance routine and has helped me achieve a thriving, healthy aquatic environment.

Il prodotto è ottimo e fornisce tutti gli elementi base. Per esperienza personale suggerisco di dosare sempre il Flourish con Potassium e le varie boccette con gli elementi aggiuntivi ossia dosare sia i Macro che i Micro. Osservare le piante aiuta a capire le loro necessità e con questi prodotti si può intervenire in modo mirato. NB: Vanno integrati per massimizzare la fertilizzazione delle piante.
