Montorchid Slow-Release Root Tabs, 100 Tabs

Montorchid Root Tabs are slow-release fertilizer tablets for freshwater planted tanks. The pack holds 100 tabs at 1g/tab. Montorchid says nutrients release steadily over 2-3 months.

Nutrient profile

The NPK ratio is 1:0.5:2.8: low nitrogen, low phosphorus and high potassium. The aim is to feed plants while limiting excess nitrogen and phosphorus that can feed algae. That makes them a fit for tanks with fish already supplying nitrogen.

How many to use

Montorchid’s guide: place 1 tab with a minimum 5-inch spacing on the tank bottom, about 5 tabs for 5-gallon tanks and 10 tabs for 10-gallon tanks. Adjust by 1-2 tabs depending on plant density.

Start low

For the first application, Montorchid suggests starting at 80% of the recommended dose, watching plant growth, then moving to the full dose. That is a careful way to avoid overloading a tank.

White haze is normal

After placing tabs, a little white suspension may appear in the water. Montorchid says this comes from slow-release trace elements such as manganese and zinc and clears in 3-4 hours. Burying tabs deeply keeps it minimal.

Placement tips

• Push tabs well down near roots with tweezers.
• Keep the 5-inch spacing to spread nutrients evenly.
• Prioritize heavy root feeders like swords and crypts.

Fish and shrimp

Montorchid describes the tabs as safe for fish and shrimp. As with any fertilizer, avoid overdosing in small shrimp tanks.

Compared with others

ThriveTabs carry more nitrogen and phosphorus. API ROOT TABS come in a smaller box. Choose Montorchid when you want a high-potassium, slow-release option in bulk.

Write the date on the bag each time you add a round, and plan the next one a little before the 2-3 month mark so roots never go without. Spread the tabs across the whole planted area rather than in one spot.
