Product Description

ThriveCaps | Premium Root Zone Fertilizer Capsules | 60 Tabs New and Improved: ThriveCaps are a very similar product to the previous ThriveTabs, with a few improvements. These capsules dont require any additives to make them stick together which allows them to be smaller and more concentrated while still delivering similar nutrient levels. Another improvement has to do with ThriveTabs causing clouding in some tanks. I changed the formula a bit to reduce this. I had a few people who had clouding issues with ThriveTabs try ThriveCaps. None of them had the same clouding issues!!!! ThriveCaps - Substrate additive for planted aquarium Contain Micro and macro elements as well as other minerals ThriveCaps are nutrient rich capsules which are intended to be placed in the substrate of a planted freshwater aquarium. They will provide a long lasting nutrient source essential for healthy plant growth. ThrivedCaps are a blend of dry Thrive mix, iron rich clay and mineralized top soil. How To Use? Place a capsule at the base of each plant or space out around the tank every 5-6" in a grid pattern. Push down to the bottom of the substrate as far as you can. Replace every 3-4 months or as needed.

good if you can get them to stay down
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.
