Sea Salt 7.5 kg Bag — Marine Salt for Fish and Soft Corals - Aquaforest

Aquaforest Sea Salt 7.5 kg — marine salt for fish and soft corals in an economy bag

The Sea Salt 7.5 kg is Aquaforest's entry-level marine salt, built for fish-only aquariums (FOWLR) and soft coral tanks. Unlike Reef Salt, this salt does not aim for the elevated macro targets that drive SPS growth — it delivers parameters aligned with natural ocean water without extra amino acid or vitamin C enrichment. Ideal when budget matters or when livestock does not require the tight parameters of an SPS reef salt.

The 7.5 kg bag makes about 50 US gal (190 L) of marine water at 33 ppt salinity (1.025 SG). Convenient format for 40-100 US-gal tanks that don't burn through salt at an SPS pace.

Which aquarium Sea Salt suits

• Fish-only aquarium (FOWLR) — fish + live rock, no demanding coral.
• Soft coral tanks — leathers, mushrooms, zoas, xenia that don't need elevated macros.
• Quarantine and hospital tanks — neutral salt for observation or treatment.
• Budget-conscious aquarists — cost-per-gallon advantage.

Official preparation

• Dissolve about 380 g of salt per 10 L of RO/DI water to hit 33 ppt (1.025 SG).
• The 7.5 kg bag makes about 190 L of marine water.
• Dissolution temperature: 24 °C (75 °F).
• Vigorous stirring for about 15 minutes.
• Refractometer check — target 33-35 ppt depending on livestock.

Frequently asked questions

Can Sea Salt be used on an SPS reef?

Technically the dissolved salt gives viable marine water, but Aquaforest positions Sea Salt for fish and soft corals. Macro parameters (Ca 360-400, dKH 8-9) are below SPS targets. For an SPS reef, choose Reef Salt or Reef Salt+.

What's the cost-per-gallon difference vs Reef Salt?

Sea Salt is Aquaforest's entry-level format, usually cheaper per kilo than Reef Salt. On a FOWLR with regular water changes, annual savings can be significant with no downside for the targeted livestock.

Should I test parameters after mixing?

Yes — regardless of which salt you use, refractometer salinity check is essential before pouring into the tank. Occasional Ca, KH and Mg checks confirm the shipped batch holds the published parameters.
