Add tropical greenery to your aquarium without taking over the tank.
The Mossari Small Aquarium-Mounted Wicking Pot is a compact self-watering planter designed to fit both rimmed and rimless aquariums. Built from aquarium-safe materials, it mounts securely to your tank and uses passive capillary action to draw water upward into the root zone.
No pumps. No plumbing. No daily watering.
This smaller format is ideal for nano tanks, tighter setups, or hobbyists who want to experiment with above-tank plant growth without committing to a larger planter.
How the Aquarium Wicking System Works
A wick extends from the planter into your aquarium water. As the plant uses moisture, water is continuously drawn upward and distributed evenly throughout the substrate.
This creates a stable, consistently moist root zone that supports steady growth without the harsh wet-dry cycle of traditional watering.
The Small Wicking Pot works especially well for compact tropical plants that prefer consistent moisture, including small trailing vines, creeping species, ferns, and lightweight foliage plants.
Substrate Options – Choose Your Growing Strategy
Customize your planter with one of two wicking substrate blends depending on how you want your aquarium system to perform.
Enriched Wicking Substrate – Added Nutrient Support
Designed for growers who want stronger establishment and added nutrient buffering in the root zone.
Includes:
• Coco coir, perlite
• Worm castings
• Kelp meal
• Neem meal
• Gypsum
Why upgrade to Enriched?
Worm castings provide gentle plant-available nutrients and beneficial microbial activity that support root health.
Kelp meal supplies trace minerals and natural growth compounds that encourage fuller foliage and stronger development.
Neem meal contributes organic matter and supports a balanced root-zone environment.
Gypsum provides calcium for structural plant support and helps maintain substrate structure.
This option is particularly helpful for lightly stocked aquariums, new tanks, or smaller systems where nutrient levels may be lower.
When used properly in a Mossari wicking system, amendments remain primarily concentrated in the root zone rather than freely washing into the aquarium.
Inert Wicking Substrate – Full Feeding Control
Designed for fully aquarium-driven nutrient systems.
Includes:
• Coco coir
• Coco chips
• Perlite
No added fertilizers or amendments.
Plants rely entirely on nutrients drawn from aquarium water. Ideal for established tanks with steady nitrate production or growers who prefer complete nutrient control.
How Much Does 6 Cups Fill?
One 6-cup bag fills:
- One Large Aquarium-Mounted Wicking Pot
- Large Wicking Pot – Self-Watering Planter
- One Oasis Planter
- Two Small Aquarium-Mounted Wicking Pots
- Two Soma Planters
Designed for Plant and Fish Health
The wicking system separates the plant root zone from direct water flow. Water moves upward through capillary action rather than pouring through the substrate.
This helps:
• Maintain stable root moisture
• Avoid heavy nutrient dumping into the aquarium
• Allow plants to assist in nutrient uptake from tank water
Why Choose Mossari
Mossari planters are engineered specifically for aquarium integration. They are not modified pots or generic clip-on containers. Each design is built around wicking performance, structural stability, and long-term durability in humid environments.
The Small Wicking Pot gives you flexibility to test new plants, expand vertically, or add greenery without overwhelming your aquarium footprint.
Create a Living System
Add compact tropical plants above your tank. Reduce manual watering. Turn unused vertical space into a functional plant-aquarium display.
