    Very Impressive Fertilizer, Because I Used This Thrive Line Products In 2Years ago. Growth Rate & Colour are Very Faster For My DUTCH Tank

  2. Rob (verified owner)

    This product (Thrive+) is working very well. My plants went from a lacklustre green to a very intense vibrant green within a week of using it. I would definitely recommend the product.

    I used to dose dry fertilizers and have had great success with that for over 10 years. When I started my new high tech tank just over a year ago I figured I’d give this a try and see how it goes. I was amazed at the results and never went back to dry ferts. Thrive + really does save you so much time and simplifies the process for both beginners and advanced hobbyists alike.

    We have been using thrive for close to a year now and have had excellent results. Definitely recommend

    It’s so convenient! But I found I have to dose double the reccomended amount daily or else I see deficiencies and slowed growth in my high tech tank.

    I wish it had some ferrous gluconate.

  6. Doug W Pluta (verified owner)

    Everything my heavily planted tank needs for optimal growth. Easy to use…

  7. kevin (verified owner)

    I have nothing but great experience with this product. I will continue to use, and suggest to anyone inquiring about planted aquariums.

  8. Corona Ken (verified owner)

    Very happy with Thrive +. Was able to see significant improvement in plant growth within one week of application. Tried others, this is the best.

    Easy to use all in one fertalizer with great results

  13. charles Walsh (verified owner)

    I was using another all in one fertilizer before I found Thrive and the difference is nothing short of amazing! Everything is green and my black beard algae is almost completely gone! Even the color of the fertilizer was a darker, richer color. I assume it has far more iron in it. Thumbs up from me!

  14. Ron Greene (verified owner)

    Easy to use and very consistent.

    I love Thrive+ and so do my plants! I am new to planted tanks and having an all-in-one bottled fertilizer has made things much simpler for me. My plants look great!

    This is an excellent product that covers all macro and micro nutrients. What I like the most is that its one bottle, versus juggling 6+ bottles. I’m surprised seachem didn’t jump on this boat. Plants even after the first few treatments are doing wonderfully. I am seeing positive growth and spreading. I strongly recommend.

  17. Corey Walther (verified owner)

    No worries about measuring the right amount, just use the squirt bottle and be on your day. Will continue to use and recommend.
