Northwater Aquatics · MMXXVI
A studio for planted aquariums
The studio · Seattle & remote worldwide
Planted aquariums,
considered.
Design, installation, and quiet stewardship across six traditions of the planted-aquarium form.
The Studio
Northwater is a studio for planted freshwater aquariums. We design, install, and quietly tend to the kind of tank that breathes in a room, not the kind that announces itself.
One brief. One studio. No equipment markup. We work with beginners and the design-curious, in the Seattle area and remotely worldwide.
Styles
Six languages of planted aquariums.
An education in form, before you commission a brief. Each style page covers origin, philosophy, plants, livestock, and the kind of room it tends to live in.
Style I
Iwagumi is governed by restraint. A single dominant stone, the oyaishi, sets the composition. Two to four secondary stones support it, never echo it. The visual rhythm is asymmetric and grounded in the rule of thirds. Plants are minimal and carpet the foreground. Everything points to the silence of the arrangement.
Intermediate
IIwagumi
Japanese stone, considered.
Style II
Where Iwagumi distills, Nature Style layers. A focal point, usually driftwood or a stone arrangement, sits in the foreground or one-third position. Behind it, plants build in tiers from short carpets to mid-ground shrubs to tall stems at the back. The viewer's eye is led from the front foreground toward an implied horizon. The result feels like a slice of forest brought indoors.
Intermediate
IINature Style
A forest cross-section, in glass.
Style III
Jungle tanks let plants grow as they will. Tall stems break the water surface. Floating plants soften the light. The hardscape, if any, disappears behind growth within months. There are no rigid rules of composition; the goal is the felt quality of an overgrown, undisturbed corner of the world.
Beginner-friendly
IIIJungle
Quiet wildness, slow grown.
Style IV
A Dutch tank is composed in rigid terraced rows, called straat (streets), each row a single species set in deliberate contrast to its neighbors. Color, texture, and leaf shape are orchestrated. There is no driftwood and no stone. Plants alone do the work.

An underwater garden, terraced.
Style V
A biotope tank is an exercise in restraint and accuracy. Wood, leaf litter, and almond bark steep the water into amber. Substrate is minimal, often just fine sand. Plants are sparse to absent, as they would be in nature. The livestock comes from a single geographic region, and water chemistry is matched to the source.

Style VI
These tanks treat negative space as a primary element. A single piece of driftwood, or a careful stone composition, dominates the visual field. Plants appear only as moss veils, tiny epiphytes on the wood, or sparse stems in the substrate. The tank reads as sculpture you can keep alive.

The Approach
How a Northwater tank comes to be.
Four chapters, from the first conversation to the moment the light comes on.
- IChapter
We begin in conversation.
A short brief, a few photos, and an honest conversation about the room you want this tank to live in. No fishkeeping experience required. That's why we exist.
- IIChapter
We design the aquascape.
A complete plan: tank size, equipment, hardscape, planting, and a stocking sequence that respects the cycling timeline. Every recommendation verified before it reaches you.
- IIIChapter
You order the materials.
You purchase directly, no markup, no middleman, no inventory we're trying to move. We hand you a shopping list and the trusted sources we'd use ourselves.
- IVChapter
We install and quietly tend.
When everything has arrived, we come on site or guide setup remotely. Optional stewardship through the first month. The part beginners need most.
Engagements
Begin where it fits.
From a single plan to a full hands-on install. Materials always purchased by you, never marked up by us.
In their words
Northwater transformed our living room. The attention to detail, creativity, and ongoing care are second to none, our aquarium is truly the heart of our home.
