Aquascaping, Design & CO2

A riparium sits somewhere between aquarium, flooded forest edge, and botanical display. This exploratory build article looks at how hygrolon, terra tape, driftwood, and controlled moisture systems can turn a calm planted tank into a living above-water ecosystem.

A faster way to create a lush planted tank: combine designed hardscape with ready-grown Wabi Kusa for an instant, plug-n-play aquascape.

Wabi-Kusa is a simple, living plant form that grows over time. Discover how it works and how you can use it in your space—from bowls to aquariums.

Iwagumi aquascaping may look simple, but it is one of the most disciplined styles to master. Built on stone placement, balance, and restraint, it teaches how to create powerful layouts using less.

Not all aquascaping rocks are safe. This Singapore-focused guide explains exactly how rocks affect pH, KH, and GH—and how to choose stable stones for planted tanks, CO₂ systems, and shrimp setups.

Why does the same pH give completely different CO₂ levels? This guide explains the relationship between CO₂, KH, and pH in planted aquariums—so you can avoid common mistakes and build a stable, thriving tank with confidence.

Choosing the right CO₂ system can make or break your planted tank.
This guide explains how diffusers, atomizers, and reactors actually work — helping you pick the best setup for healthy plant growth, clean aesthetics, and long-term efficiency.

Learn how to build a smooth, continuous underwater sand waterfall using a simple airlift system. This guide covers the physics, piping design, and external air pump setup to help you create a clean and reliable loop with confidence.

Not sure whether to use aquasoil, root tabs, or liquid fertiliser? Learn how each works, their key differences, and how to choose the right combination for a healthy planted aquarium.

Not sure whether to use root tabs or liquid fertiliser in your planted aquarium? Learn how aquatic plants absorb nutrients, the key differences between substrate and water column feeding, and why most tanks need both for healthy, balanced growth.

Starting a planted tank can feel overwhelming, but it becomes simple when you understand the essentials. This guide explains what equipment you really need — from lighting and CO₂ to filtration and substrate — and how each part works together to create a healthy, balanced aquascape.

Aquascaping is the art of arranging aquatic plants, rocks, driftwood, and substrate inside an aquarium to create a natural underwater landscape.

In a CO₂-injected planted tank, the goal is to keep CO₂ dissolved in the water for as long as possible so plants can use it for photosynthesis. However, many filters create strong surface turbulence, which causes CO₂ to escape into the air. This reduces CO₂ efficiency and can lead to unstable plant growth and algae problems.

Utricularia gibba is one of the hardest to remove once it's lodged in your mosses or hairgrass.

Red stem plants are arguably the most demanding of plants in the hobby but they are also the most striking..
