Fauna Marin Professional Sea Salt
Fauna Marin Professional Sea Salt is a German made reef salt developed alongside coral farmers for tanks that need steady, repeatable water chemistry. It carries the full range of macro and trace elements corals use to grow, blended to track natural seawater, and it is ready to use about 5 minutes after mixing. Build your reef with corals and saltwater supplies.
Why This Salt
- Full spectrum of macro and trace elements dosed for coral growth
- Every batch is ICP tested by independent labs and Fauna Marin's own in-house lab, so parameters stay consistent from one mix to the next
- Made from pharmaceutically pure salts and low in unwanted impurities
- Mixes fast and clear and plays well with skimmers, reactors, and modern filtration
- Reef range calcium, magnesium, and alkalinity straight out of the mix
Target Parameters
Values when mixed to 35 ppt (about 1.0264 specific gravity). Confirm your own number with a refractometer, since source water and mixing gear can shift the result.
| Salinity | 35 ppt (1.0264 specific gravity) |
| Calcium | 410 to 440 mg/l |
| Magnesium | 1,250 to 1,340 mg/l |
| Alkalinity | 8.0 to 8.5 dKH |
| pH | 8.0 to 8.4 |
How to Mix
- Mix with RO or RO/DI water for the most consistent results
- Add salt to water slowly with a powerhead running, never water to salt
- Circulate and aerate until fully dissolved and clear
- Confirm salinity with a refractometer and target about 1.0264 (35 ppt) for reef tanks
- Let the batch stabilize and match your tank temperature before a water change

FAQ
Is this a reef salt or a fish only salt? It is a reef blend with elevated levels for coral growth, and it works well for fish only and FOWLR tanks too.
How much salt do I use per gallon? Roughly a half cup per gallon lands near 35 ppt, but always confirm with a refractometer because mixing containers and source water vary.
Do I need to mix it before adding it to the tank? Yes. Mix and aerate in a separate container until the water is clear and stable, then check salinity before dosing.
Where is it made? Fauna Marin Professional Sea Salt is made in Germany.
