Why it earns its place

Less spreadsheet wrangling, fewer call-backs, sign-off you can defend.

Stock survives the load

Oxygen and ammonia balanced to your biomass and feed rate, so the system carries the fish, not luck.

Biofilter sized right

MBBR / fixed-film media volume matched to the nitrogen load — no crashes, no over-build.

Water you can afford

Make-up and exchange rates that keep quality up and pumping costs down.

Every result, on your letterhead

One click turns any calculation into a clean, fully customisable PDF report — branded with your company logo, ready to drop into a submission, quote or design pack.

  • Your logo, company name and project details on every page
  • Inputs, results and the method, all documented
