Reef Salt Box 5x5 kg — Individually Sealed Bags of Fresh Reef Salt - Aquaforest

Aquaforest Reef Salt Box 5×5 kg — five individual bags of reef salt for maximum freshness

The Reef Salt Box 5×5 kg bundles five individually sealed 5 kg bags inside one cardboard master box. Each bag stays sealed until opening — the go-to option for reefers who prep water in advance and refuse any freshness compromise. The Reef Salt recipe stays the same: amino acids and vitamin C, balanced macros for SPS and LPS reefs.

The box holds 25 kg of salt and makes about 170 US gal (645 L) of reef water — more than a quarter of regular water changes on a 65 US-gal reef, or a strategic reserve for multi-tank households.

Why the 5×5 kg packaging

• Peak freshness — four bags stay factory-sealed while only one is opened and being used.
• Multi-tank setups — handy for households mixing 5 kg batches at a time.
• Bulk buyers — better per-kg price than a 2 kg bag, without the long air exposure of an open bucket.
• Frag shops and stores — each bag opened on demand with no waste.

Frequently asked questions

How long does an opened 5 kg bag stay usable?

Resealed into its original zip bag and kept dry, an opened 5 kg bag lasts several weeks without notable degradation. The whole point of the 5×5 kg format is that the other four bags remain factory-sealed.

Are all five bags from the same production batch?

Yes — the five bags come from the same packaging batch. The lot number is printed on each individual bag for traceability if needed.

How much total water does the 5×5 kg box cover?

25 kg of salt make about 170 US gal (645 L) of reef water at 33 ppt salinity. On a 65 US-gal reef running 10 % weekly water changes, that's about 26 weeks of coverage — more than six months of standard operation.
