ThriveCaps Aquarium Root Cabs – Premium Root Fertilizer for Live Plants – Slow Release – Strong NPK + Micros – Safe for Shrimp & Snails – 60 Count

I’ve been using this for month and I would not get another root fertilizer. It does exactly what it’s supposed to do and it’s easy to apply. Super effective and the plants love it. Good sized tablets. Providing nutrients for a long time

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.

They are great when they work. Although they are very floaty, all my fish, shrimps, and snails go absolutely crazy as soon as they smell those fertilizer tabs in the substrate, and all dig my substrate upside down, and feast on it within half an hour. To be honest, I don't know what I should do.

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.

These are awesome for my planted aquarium! They're a good value and my plants are thriving. Well worth the money!

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

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.

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!

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
