Give your rooted plants a direct line to the nutrients they crave. These root tabs pack a complete blend of nitrogen, phosphorus, potassium, and trace elements — with a low-N, low-P, high-K ratio dialed in specifically for healthy, vigorous plant growth rather than feeding algae.
 
Simply press a tab into the substrate near the root zone, where each 0.8g tab slow-releases nutrients for 2–3 months of consistent feeding — no dosing schedule to remember, no guesswork.
 
Best of all, these tabs are fully shrimp-safe, making them a great fit for planted shrimp tanks where water sensitivity is a real concern. Hobbyists have used them successfully in caridina shrimp setups without any casualties — and some have even reported increased breeding activity after fertilizing, a good sign of a healthy, low-stress environment for your colony.
 
Each jar holds 80 tabs, with one tab covering roughly 10cm of substrate, giving you plenty of fertilizer on hand for a heavily planted tank or several smaller setups.
