This guide is written as an operating framework. Exact limits still depend on the organism, system volume, equipment and local rules.
Use the right zone
Marginal plants, lilies, submerged oxygenators and floating plants need different water depths and anchoring. Place each plant for its growth form.
Contain runners and roots
Baskets and physical barriers make maintenance possible and reduce damage to liners or drains.
Prevent complete surface cover
Floating plants can block gas exchange and shade submerged growth. Harvest before they form a sealed mat.
Check weed status before buying
A plant sold online or interstate may be restricted locally. Use current official weed and biosecurity sources.
Dispose on land, sealed and dry
Never throw living fragments into drains, creeks or dams. Dry or securely bag material according to local rules.
