A reef tank planned right is half the problem solved.

Most reef tanks that develop chronic problems started with improvisation. Glass off-square, undersized sump, weak return pump, lighting that does not cover the footprint, stocking plan without compatibility — each decision becomes a headache (and lost money) six months later.

The ReefFlow Aquarium Planner is a step-by-step wizard: dimensions and net volume, compatible equipment selection (light, return, skimmer, ATO, doser), aquascape, stocking plan with compatibility checks, total budget and maturation timeline. You leave the wizard with a document — not a surprise box.

Output is exportable (PDF) and saved to your account. Use it as a shopping checklist, share with your LFS, or convert it into an active tank when you start.
