Saltwater is a different hobby
A saltwater tank — reef or fish-only — runs on chemistry a freshwater logger was never designed for: alkalinity, calcium, magnesium, and salinity as first-class parameters, dosing as a daily practice, and livestock whose compatibility and care differ completely from community freshwater fish. An app built freshwater-first fights you on all of it.
Reef Trak starts from the marine side: the parameter panel, target ranges, dosing tools, calculators, and species catalogs are all saltwater-native. FOWLR keepers get the same benefit — marine-appropriate tracking without coral-specific clutter.
What's inside
Free to start, honest to own

Saltwater aquarium app — FAQ
What is the best saltwater aquarium app?
One designed marine-first: full saltwater chemistry, dosing tools, marine livestock catalogs, maintenance reminders, and multi-tank support. Reef Trak is built exclusively for saltwater and reef keeping.
Does Reef Trak work for FOWLR tanks?
Yes — fish-only-with-live-rock tanks get the same marine parameter tracking, maintenance, livestock, and equipment tools; you simply use the parts your tank needs.
Does it handle quarantine tanks?
Yes — every tank gets its own complete history, so display, quarantine, frag, and nano systems each stay organized separately.
Is there a web version?
Yes — the Reef Trak WebPortal at reeftrak.com gives you big-screen charts, reports, and management alongside the iPhone and Android apps.
