    I attended the AGA conference last spring and collected samples of several brands of ferts to try. Thrive was the clear winner for my tank! I saw significant growth and color saturation. My plants perked up within hours of dosing!

  2. David (verified owner)

    Unless you plan to make your own ferts it is hard to find a product that works as well as Thrive. Thrive was a game-changer for my planted tank. If you are struggling with plant growth then look no further.

    I have used this for a couple of years now. I am on my 5th gallon of it. It is great. I dose it automatically 1 hour before the lights come on and start my co2 2 hours before the lights come on. This combo has worked great for me.

  3. Shannon Montgomery (verified owner)

    I saw results almost immediately everything seems greener or more red even plants that usually lay down are up and happy I will definitely be ordering more soon.

  4. Nick Sarfaty-Jackson (verified owner)

    An amazing all in one liquid fertilizer, repeat customer and very happy.
    This is an excellent product and its probably the best deal for a comprehensive liquid fertilizer out there!

  5. Collin Abler (verified owner)

    Feeding 6 tanks….. way more economical than any other fert I’ve found for planted tanks!!!!
    Look no longer, if you have been looking for something fantastic and just feel as if you haven’t found the right thing……this is that right thing, but the biggest bottle and a dosing bottle and you cannot go wrong!!!

  6. Mark (verified owner)

    This is my second order of Thrive – first bottle lasted about 6 months (I’m dosing 3x weekly). Used on my 40 gallon dirted low tech with mix of stems and heavy root feeders. Plants are doing exceptionally well with algae being kept at bay. The dosing pump is a very nice addition for simplicity plus Thrive doesn’t need to be refrigerated 3 months after opening.

  7. Penny Crowley (verified owner)

    Long time dry fert user- I had a large tank. When I switched to a nano cube, I switched to Thrive. SO MUCH EASIER. One pump 2x a week and my plants are growing with no algae! Thanks Colin, for such a great product!

  8. Robert parker (verified owner)

    This here is good stuff. Will keep your plants happy and perky without bothers your fish. And at a price that won’t break the bank. Can’t beat it. Plus you can always message Colin and he is very helpful.

  9. Jordan (verified owner)

    Great product that is easy to use! Results within the second day following the instructions. Using in 5 gallon tank with half pump after 50% water change on Monday, Wednesday, and Friday.

  10. Jason Paull (verified owner)

    Was looking for an easy to use, reasonably priced all-in-one product. Thrive has been great for all my tanks!

  11. Melanie Downs (verified owner)

    I just dosed my 40 gallon long today for the first time. I had some beautiful plants I ordered come in today and was excited to use the Thrive. I belong to a planted aquarium group on Facebook and Thrive was highly recommended when I asked for the best fertilizer. I am new to planted aquariums and so excited to use Thrive. Since I just dosed I haven’t seen the results yet but the pictures I saw of people’s tanks who used Thrive were absolutely beautiful and so green and healthy.

  12. Thomas Morris (verified owner)

    Ive only dosed twice and the plants are growing like crazy! Highly recommend!

  13. Travis (verified owner)

    1st time user. Will definitely refill when the time comes. All my plants look much better within a week. Lots of new growth and old growth repaired. I used the regular Thrive in a tank with a few shrimp and see no harm to the shrimp. Would definitely recommend!

  14. Anonymous (verified owner)

    As others have mentioned, the killer aspect of this is the convenience of being just one bottle. Having a pump top is something I’ve always thought would be best for liquid ferts and this one works great. I have a somewhat new (>1 year) low-light tank and after an initial big growth spurt when all the plants were added things slowed dramatically. It was evident I wasn’t going to be able to get away with only dosing flourish carbon. First dose of Thrive showed results the same day. 90% of the plants with dropping leaves perked up. Algae has woken up some, too, unfortunately. I waited about 5 days before dose two and things perked up even more. But given the algae response I think once a week will be good. Summary: great 1-bottle solution for ferts. Mixing powders and multiple capfulls of multiple bottles is just silly in comparison.

    Ive only used this product for roughly a week so my review should not hold as much weight as others. That being said, im very happy so far. Shipping was very very prompt and arrived from across the US in 3 days, including a Sunday. The product composition is superior to Seachem Flourish. The product was recommended to me from Luke Westcott at Fintastic Fish in Bellevue, NE. Thank you colin.

  16. amy lund (verified owner)

    No more 10 bittles on the shelf for fertilizing. Love this easy to use no more measuring.

  17. Cindy (verified owner)

    Aquarium newbie – I started using Thrive for several months in a planted 20g tank. All plants immediately perked up within a few days of first use, and with the EI method I’ve kept the tank healthy and stable. Easy to use, and customer service was great. The pump dispenser was omitted from my original order – Colin sent it to me ASAP when I contacted him. Will definitely buy again.

  18. Susan Jackson (verified owner)

    I love this! So easy to use and perfect for my plants. Just a pump per 10 gallons. My plants have never looked better. They have great customer service!

  19. chad Hopkins (verified owner)

    Fast shipping, great product, easy to dose. Will be buying more

  20. Leslie Adams (verified owner)

    Ive used this fertilizer for over a year, in both a play sand planted tank, and a flourite planted tank, and had nothing but great healthy growth. I even experimented by stopping the fertilizer for 2wks, just to see if there was any difference, and my plants growth slowed down considerably. I do not use Co2 or grow lights, just a regular fluorescent light. I highly recommend!!.

  21. andy (verified owner)

    Dosed my tank for first time about 3 days ago, plants are all ready shooting new roots and stems.

  22. Anonymous (verified owner)

    I am an experienced aquatic gardener, and have used dry fertilizers to make y own stock solutions for years. That certainly works. But Thrive is so EASY!!! Even when I’m away, I can safely tell care-givers “3 pumps in this one, 7 pumps in that one.” Results are undeniably good. I am recommending this products to all beginners now. No confusion about how much of what to feed, just pump it in! 🙂

  23. (verified owner)

    I have noticed a bit more purling after about 6 days. Small new growth. BBA still seems to be hanging on but not advancing.
    Definite improvement and I would recommend this product.

  24. Jacob Fuchs (verified owner)

    Makes liquid dosing extremely simple and easy. The plants love it.

  25. Adam Coker (verified owner)

    I have been using Thrive in my 46g low tech/medium light tank for 2 weeks now and I can already see a huge difference in my plants. Not only do they look healthier but they have a lot of new growth. I had been using all of the Seachem Flourish products and Thrive is not only easier to use but it works 10x better. I also got great customer service when I had a couple of dosing questions. I received a message back in less than a hour. Where can you get customer like that anymore and you are actually getting what you pay for? I have just found the last fertilizer I will ever buy!!!

  26. Alex – (verified owner)

    Very happy with my purchase! Plants love it! Would definitely recommend to anyone in the hobby!

  27. Anonymous

    It has been a couple of weeks since I received my order. I haven’t noticed a major difference in plant growth as they were healthy to begin with and are slow growers, but I do love this product regardless. Gone are the days of having to deal with measuring and mixing. I also do not miss having to deal with the mold problem which always bothered me.

    I would definitely recommend this product to anybody in the planted tank hobby whether they are a newbie or a veteran with years of experience.

    Been a customer for several years and have always have been very satisfied with NilocG Aquatics products and service.

    Thrive is no exception to this, very impressed with the quality and ease of use to a single fertilizer to provide EI levels. I have been mixing my own from dry frets from NA for a long time but getting things consistent and stable for long durations can be tough when mixing your own. Thrive just simplifies it and makes it so much more concvient.

    Thanks NA!

  29. (verified owner)

    It’s a great product! Very straightforward and easy to use.

  30. Rob D (verified owner)

    I’m almost out of my first bottle, I switched from excel and have seen my melt problems with swords dissappear and new growth. Since using it growing plants has become easier and the plants thrive(no pun intended). Alage has almost totally disappeared but enough left for my guppies, platties, shrimp and octos to feed on. Plants are greener with strong stems and better roots. Will be time order more. Test it out and see the difference for yourself. Easy to use no mixing or messing around, just squirt in the required amount and see your plants become fuller and healthier. Crypts look great, java fern full of babies, I really can’t say enough good about Thrive. So you be the judge and try it out, I think you will be happy you did. I actually adjusted how much I used less and more to see if it mattered, I used a little less then directed and things are still growing well.

    Been using for a while now and plants combined with C02 have been doing great, good product and great price.

  32. Corey Walther

    After using Seachem for months I decided to give nilocg a try. I have seen more growth in 9 days of nilocg than over a month with Seachem.

  33. Harvey Williams

    Added this product 6 days ago for The first time..after 24hrs..I noticed that the BBA.WAS TURNING RED.And dying..after 48hrs I noticed My Ludwigia.was more redder ang sprouting new good looking far so good…will update any good or bad things happening…

  34. Gabe

    I was using an API fertilizer and my plants slowly started looking bad. So I decided to try this and literally the morning after I dosed my plants started growing healthier. I still can’t believe it. I gotta see what happens long term but so far I love it.

  35. Marie

    I’ve been using this about two weeks. Previously I was using eight different bottles of SeaChem products. I got great results from those, but I love not having to haul out all of those bottles! Being that it’s been such a short time, I can’t say that this is “so much better” but I have not seen any negative effects on my plants. If the growth even stays the same this product will be worth it!!

  36. Eric Carroll

    After years of experimenting with various fertilizers (often falling back pps pro or ei) I decided to give Thrive a try, hoping that its ease of use would out weight any functional shortcomings. I was extremely pleasantly surprised when, after several months of use, I found that not only was it easier to use than any previous method i had tried but the results surpassed every other method. I am now a devoted convert and I have convinced many friends to try Thrive as well and each is just as happy as I am.

  37. Cyndi

    I’ve noticed considerable growth since using this product. Everything is so green and red. Will be sticking with it!

  38. Kevin B

    I’m not a chemist and I have other things to do than sit with little spoons and measuring devices concocting fertilizer dosings. Instead, I bought Thrive and a pack of the clay capsules and couldn’t be happier with the results; new tank and plantings but only two weeks into it and the plants/grass are exceeding my expectations at this point in the process. I am injecting CO2 as well, to be fair, but I firmly believe that the combo of these ferts and CO2 make my tank an ideal environment for my plants to thrive.

    On another note…I want to really underscore the great customer service the folks at NiLocG provide…emails are answered promptly with thoughtful responses the guided my selection…and they were spot on.

    I never used liquid fertilizers before (always dry) but this product is awesome. I do a couple pumps a few times a week and that’s it. Its a major time saver and is just as effective.

  40. Ben

    Im in love with this fertilizer! I was skeptical at first dosing twice a week. Now my plants are green, healthy looking and im seeing new growth within 2wks of using this product. I look forward to future and more purchases!!!

    Just ordered and received my 2nd bottle of this. I’ve had nothing but amazing results since switching to this from the standard dry EI and DIY EI liquid ferts, also from this site. My tanks have been completely balanced since switching to Thrive as well.

  42. Joe Turrigiano

    Just started using but can see results in just first 3 days plans are thriving that looked as if they were melting before the use of this product.

  43. john eldredge

    This is the easiest and most effective method I’ve used yet. I didn’t want to be mixing and measuring, this is just 1 pump per 10 gallons. Growth increase is phenomenal. I was using seachem products, I run 6x 54watt t5 ho and co2. My Val’s have doubled in thickness, my swords are putting up a leaf a day, my red lotus and red stems are RED! I have 25 varieties in my 120 gallon tank, they have all improved. They were pretty good before, but now they are great! Thanks for a great product! I need a 55 gallon drum of this stuff!

  44. Mike

    Ordered on a Sunday and received it Wednesday. Switched from EI dosing and have already seen improvement in some plants can’t wait till it really kicks in.

  45. jose rivera

    Thanks to ppl from the planted tanks on Facebook helped me find a great product an all in one product only thing it was smaller then expected but over all I’m pleased with the product I’m a customer

  46. Rob Jones

    Well I have only been using thrive for a few days. I can’t give it 5 stars yet. But so far it seems to be working well. Would I recommend? Yup what do you have to lose? Thrive has been a crave for awhile. My plants have done just fine while being on thrive 100%. I believe it is shit hot and will continue to use it daily. It is simple to use which is like!!!! Just aim and squirt, no more syringes!!!!

  47. John in Ohio

    bought on recommendation that with it being a 3 part all inclusive plant fertilizer, noticed after one application, a dramatic difference in color and new growth stimulation. Highly recommend and will be buying more when needed, this is my NEW FOREVER all inclusive aquarium plant fertilizer. Thanks NilocG

  48. Donovan Maxwell

    At the moment it is too soon to be able to tell any real difference in the plants in the tank. The directions and label are clear and easy to understand. The packing the product was shipped in was good and shipping was prompt. Communication with the owner was quick and easy and he answered my questions quickly. After a few weeks I’ll post another review once I’ve had the fertilizer going long enough to judge the results.
