Thrive Aquarium Liquid Plant Fertilizer – All in One Planted Tank Plant Food - Two(2) 500ml Bottles

Excellent and cost-effective. I'm using this in a 20 gallon long tank. Had some jungle val I put in the tank in March, 6 months later it had barely grown any - and from what I've seen and heard, that's super unusual for val, and did not fit my vision for my tank. Started using this in September (and added more root tabs too), and the val is doing beautifully now, as are my anubias and swords, even the buce is starting to grow! I dose 2 pumps at water changes, and do not add if I skip a water change. Everything is looking nice and healthy and green! My windelov is pumping babies out all over the place too!

This fertilizer is amazing. I have a low tech tank, aka an led light thats on for about 5 hrs a day and no co2 or anything of the sorts. I have a bacopa, Java fern, and amazon sword. Even though the amazon sword is technically a root feeder, all 3 types of my plants have EXPLODED in size, I'm talking 2x almost 3x size compared to before. I was dosing *ahem* flourish before with no results. This stuff really does work great.

I Have a 55-gallon planted aquarium. Was using Sea Chem fertilizer with limited success. Have been using Thrive since September and the plants never looked better. I dose a bit less than they recommend, 5 pumps 3 times / week. The nitrates are around 10 ppm, the pH slightly below 7.0 and minimal algae problem. I am very satisfied with Thrive fertilizer.

my first tank had no hope. plants dying left or right. after about a month of having the tank i started using this fertilizer and it saved all my plants. my tank is now so luscious and green. it’s also very beginner friendly. 10/10 recommend. 100000% worth it

My plants love this stuff and so did the green algae. Had to back off on the dosage to once a week. This of course was no fault of the fertilizer.

My husband bought this and says it works great on the plants in his aquarium. Nutrients seem to be very balanced. The plants are thriving.

Great fertilizer and easy to use.

My plants absolutely love this stuff and it is so easy for me to use. I admit I am pretty forgetful and lazy when it comes to fertilizing, so the Thrive line of liquid fertilizers are right up my alley. I have several low tech, heavily planted tanks and I definitely noticed a difference in my overall plant health within a week of using this stuff. This is like plant crack ;P I have new growth everywhere and my floating plants are going bananas, which is good news for my trio of goldfish. The 3 little piggies love to nom on the trimmings. For those with invertebrates: My amanos, nerites, and bamboo shrimp do just fine dosing this, the original version of Thrive. I do my 25-30% water changes about every other week. I do dose more than the amount recommended for low tech setups, but I also spread the dosage out over 4 days instead of dosing all at once. My tanks are heavily planted riparium style with both emergent and submerged growth, quick growing vals, swords, crypts, and out of control floaters. They are understocked critter wise and I have a hard time keeping even my nitrates above zero. Your mileage may vary, of course. If your tank is lightly planted with mostly slow growers like anubias, mosses, and java fern, my schedule is not going to work for you. Everybody’s tanks are different, so you need to use your best judgement and figure out what works best in your tank. I can only share what works for me in my situation. :) In my opinion though, as long as you have an etablished, adequate sized, and healthy growing plant mass, and keep up on your water changes, I don’t forsee a problem with the low dose of copper in this fertilizer harming invertebrates. NilocG Aquatics also makes a shrimp specific fertilizer, Thrive S, for those that are still worried. I have used that one in the past for the greater part of a year and it works pretty darned well. I would think it might work especially well for overstocked tanks where one might have a problem with nitrates building up (it adds a lower level of N with each dose).

Works well

You can’t use this product blindly you have to test for nitrates. My water changes rate from weekly to every 10 days @ 50%. When the product arrived I was 5 days since a water change. I read some of the bad reviews of people getting algae, and having to do multiple water changes to control algae, etc. I read a great review where the user said test nitrates. Using this product in 3 planted tanks. 120gallon, 90 gallon, 45 gallon. I used to used seachem products. It was okay but you had to do a lot of testing and dose nitrogen and phosphorus on top of comprehensive because comprehensive is week. It’s expensive and I went away from it because it takes a lot of time. Great results though. I went to comprehensive alon and it garbage. Let’s talk about this product. It is potent. Tested tanks before adding and all 3 tanks we 0 ppm nitrate. I added this product as per directions since I was at 0ppm. A day later I tested the water and there was a slight increase in nitrates but not what I had hoped for. So initially I wasn’t impressed with the products. Couple of days later nitrates easily over 10ppm but safe. Fast forward, do my next water change. Wait two days test water before adding and bam already at slightly over 10ppm nitrate. I couldn’t imagine what happens to users that don’t test and add this product blindly. Test water. Use caution. This product is potent and works really well at providing results in your planted tank.

It's a pretty good all-in-one fert, fairly good value compared to some others. I would suggest starting with the 500ml bottle and getting a 2L bottle later for refills. I would also suggest ignoring the instructions on the bottle and instead dose using a digital TDS meter. Reason being the bottle's instructions give a heavy dose which I found results in high nitrates that can stunt plant growth and cause issues with green dust algae. What I'd suggest instead is to measure your tap water with a TDS meter and dose ferts daily to maintain your tank at a TDS that's about 20-40ppm higher than your tap water. Ensure you do a minimum 50% water change weekly to keep nurtrient levels stable long-term. In my case, my tap water's TDS is 165ppm, at the start of the week my tank's TDS is 185ppm, at the end of the week, tanks TDS is around 205ppm. Then at the end of the week, I do a ~50% water change to bring the TDS back down to 185ppm. To maintain these levels on my heavily planted medium-high light 60 gallon tank, I dose about 2ml daily which is comparable to the bottle's low-medium light dose.

It works well, not the best one out there

Beautiful stuff, and my results were instantaneous. Lasts fast longer then I anticipated, which has been a welcomed surprise. Just alternate with flourish advance, or another supplement. I literally use this product 2 to maybe 3 times a week and flourish advance in between. His bazooka atomizers are crap stay away from them they basically rot in the water from poor manufacturing and no amount of bleach in this world will clean them... Then the co2 is forced into big bubbles that flow from the seams.
