ThriveCaps | Aquarium Root Fertilizer Tabs Caps 60 Count

These aquarium plant root tabs are an excellent, affordable option for anyone looking to nourish their plants without breaking the bank. They’re easy to use and provide a noticeable boost to plant growth. My plants have been thriving since I started using them, and the results are impressive. They seem to provide just the right amount of nutrients.

Great healthy plant growth.

They tend to float up to the top every once in awhile but it's no big problem and they work good.

First thing I noticed when I received my new order of root tabs was that the bottle was different and smaller. Suspicious and a little stressed, I opened it to see it packed with the familiar root tabs I've come to love and trust. I didn't count them, but I can definitely estimate that they put 60 in there.My swords love these and I've never seen them grow bigger and greener on anything else. Awesome price for a reliable product.

These things work really well from I can tell about them. My plants always look great. Although I do use aqua soil. I freeze it and then insert into root area. However I do not go without these for too long. Compared to API Root Tabs you get quadruple the amount for the same price (more than quadruple I believe) and Ive never had a bad experience with this. In face the capsule is easier to put in as soon as the API brand hits the water starts dissolving (not bad but you can see it start) but with the thrive caps no such dissolving. A+++

UPDATE 6/25/24. Today I decided to finally get some new plants to replace all of the other ones that died after using this product. The oily bubbles that I mentioned in my previous review took months to dissipate even with water changes and me cleaning out the canister and sponge filters. Today, I emptied about 30% of the water to make placing the new plants a tad bit easier. I'd like to mention that normally when I clean the tank, I just lightly run my fingers across the sand and poke holes with my finger deeper in the sand throughout. The tank was already clean so all I needed to do was plant today. As I inserted the plants which must have been in a lot of the same spots where I had plants before, I unearthed lots of residual fertilizer that was placed 8 months ago. I thought I had gotten rid of it but deep in the sand, there was more. I sucked out all I came across and continued to plant. 2hrs later, I went to look at my oasis and something was off. The plants were all still planted, the fish looked happy but something was off. Then it hit me. There wasn't a Panda Corey in sight and they're usually moving about on the bottom. After closer inspection, I see that one was eaten with a few remnants scattered about and 3 were dead under a piece of wood. All was well until I disturbed the old fertilizer that was buried deep in the sand. The water parameters are still good so no spike there and the larger fish appear to be fine. Also no oily bubbles so I assume that comes from the capsule and not the contents. Whatever the case, save yourself the headache and buy something else.ORIGINAL POST- I've purchased these 3 times and this last bottle was definitely different from the others. Normally you have a hard time getting them to stay down but this time they actually sank. You would think that's a good thing but no! When you push it in the sand it disintegrates on contact and you have fertilizer going everywhere. A day after using, I noticed that 4 of my plants were not looking too good. A day after that, they were almost transparent and a day after that, what was left of them was mush. When I went to remove them, they were so soft that they just fell apart and I had to catch the debris with a net. In my other tank, I only have 1 plant. I see that this ones bulb is starting to look rather mushy towards the top. I've also lost 4 fish over the last week. Seeing that the only change to the tank is the use of this fertilizer, I can only assume that it is whats killing them. I've had them for almost 2 years so these sudden deaths are quite alarming. There's also oily, thick bubbles on the surface of the water. I have been using the all-in-one liquid fert for years with no problem but I'm done with the capsules.

I was gifted a huge Amazon sword plant and it was going yellow from lack of nutrients. I have gravel in my tank and didn't want it to die. I used 2 of these capsules and buried them in the gravel next to its roots. By the next day half the yellow leaves were gone! The next few days the yellow leaves were gone and the plant grew. Super happy with this product!

I'm not sure whose idea it was to enclose the fertilizer in a gel cap with air inside, but this is not ideal. The goal is to shove the capsule into the substrate. This is very difficult, when the capsule floats. Also, about 20 minutes after inserting the capsule, the casing pops out and floats to the top, leaving the fertilizer behind. This is weird and undesirable.My first batch of root tabs, from API, sank. I will probably put this product on the back shelf as a backup, and buy different root tabs that sink.
