Buying guide

Before you add to cart

Ask us anything
How do I choose the right piece?

Start with the job it needs to do: create a focal point, add shelter, build height or connect other forms. Then consider the footprint and open swimming space in your layout.

Does it need prep before it goes in?

Rinse each PLA or PETG piece before use. Dry-fit the layout outside the tank first, then secure the arrangement, plant and flood slowly.
