ThriveCaps | Aquarium Root Fertilizer Tabs Caps 60 Count

I love these capsules. They don't dissolve like the API ones while you're trying to get them in the substrate. If you pinch them and let the air out, they do not float. I've been using these about 3 months now, and have not had any come back up. My plants are all looking very healthy and green, and are growing much faster now. Also super cost effective!

Plants are growing like crazy, and it the tabs haven’t messed up my water quality. This is in a gravel substrate too, so you know they’re good of these tabs are all my root feeder plants need.

These fertilizer tabs do the job, but there’s nothing particularly great or bad about them. They work as expected, but they don’t stand out in any way. Just average, nothing to really love or dislike.

Works well to keep certain plants to thrive in a gravel tank. They do float so you have to be careful when inserting them. I use a long, bent arm tweezer to push into the gravel.

I’m in the middle of redoing my aquarium. I had pool filter sand while using seachem flourish tabs. The tabs turned my aquarium into a swampy mess and my sand smelled horribly like sulfur. I couldn’t get rid of the smell and my plants started dying back . I had to take action before all of my plants died off. I got rid of the pool filter sand then replaced the with black diamond blasting sand instead. Looks and smells better already. Hopefully these tabs are worth the while. Never using flourish tabs again, my old sand was perfect before

My plants love it! I take a needle and carefully poke a tiny hole in both sides of capsule before I bury it in the substrate. That way it doesn't try to float up especially in sand substrate.

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 have two tanks - one moderately planted with gravel and sand, and one heavily planted with sand. I swap plants back and forth sometimes, and the plants definitely grow better in the heavily planted, sanded tank. I figured root tabs might help the moderately planted gravel sand tank, and I have a couple of plants in the sanded heavily planted that would benefit as well. I started with Seachem Flourish tabs from my lfs just to get started. Pricey per tab. NilocG is well regarded in the community, so I checked them out. The full set of nutrients and price per tab made the purchase a no-brainer. I put several in at strategic locations throughout the larger, moderately planted tank. I quickly noticed a significant rise in nitrates. I suspected the NilocG tabs, and a bit of research confirmed this. This did not occur with the Seachem tabs. I guess that's the trade-off for a full set of nutrients. If you're dosing an all-in-one liquid fert, is a full dose of ferts necessary at the roots, or is just supplemental adequate? I don’t know. In the moderately planted, gravel and sand tank they seem okay. I have good target spots to put them; plant growth has been good lately. The ones under gravel seem to stay down under the weight, and I put it under a rock at the one sand spot. The other tank, however…I can't get the capsules to stay down at all. Ever. If my life depended on it. Can't do it. Tried every technique here including punching holes, and some others I thought up. They either erupt as I'm wrestling with them, or they will gradually crest out of the substrate. They semi-dissolve quickly, so if you don't get them in right away, trying to push them back will just rupture them. They attract my corys, though, and they're fun to watch. Besides the fun corys, about they only thing these are good for in my sanded, heavily planted tank is releasing fertilizer into the water column and jacking up my nitrates.

Tres bon produit pour les racines des plantes et pour la santé des plantes.

Pour mes plantes bon pruduits

My plants seem happy. People who complain about these floating either don't have enough substrate or aren't following the directions and shoving them in deep enough.

Great product. My plants have doubled in size in a month
