Step by step
The Tank Planner walks you through tank size, archetype, equipment, water chemistry and stocking, then gives live verdicts on size, chemistry, compatibility between species, equipment, bioload, lighting and structural weight.
Substrate and structure
The planner is substrate-aware, with pH, KH and density effects factored in, and it estimates the weight and floor load of the finished tank. It ends with a personalized seven-phase setup guide from hardware through cycling, stocking and maintenance.
