Saltwater aquarium app

A saltwater aquarium app built for marine tanks, not adapted to them

A saltwater aquarium app should be marine-first, yet most aquarium apps are freshwater tools with a salinity field bolted on. Reef Trak is built saltwater-first: marine chemistry, reef dosing, marine livestock catalogs, and the workflows salt tanks actually need.

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.

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.
