Seachem Safe is the complete and concentrated conditioner for both fresh and salt water.

Safe removes chlorine, chloramine and ammonia.

Safe converts ammonia into a safe, non-toxic form that is readily removed by the tanks bio-filter.

Safe may be used during tank cycling to alleviate ammonia/nitrite toxicity.

Seachem Safe detoxifies nitrite and nitrate, allowing the bio-filter to more efficiently remove them.

Safe is non-acidic and will not impact pH.

Safe will not over-activate skimmers.

Use at start-up and whenever adding or replacing water.


To remove Chlorine: use 1 measure to each 60L (15 gallons*) of tap water (removes 1 ppm).

Chloramine: use 1 measure to each 75L (20 gallons*) of tap water (removes 1 ppm).

Ammonia: use 1 measure to each 11L (3 gallons*) of tap water (removes 1 ppm).

Do not overdose!

For reference, 1 measure = 100 mg.

To detoxify nitrite/nitrate in an emergency situation use up to 5 measures to each 40 L (10 gallons*). Use fish to gauge toxicity reduction as test kits will still show presence of nitrite/nitrate even when detoxified.

May be added to aquarium directly, but is better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. If temperature is 30C (86 F) cut dosing in half.

Certain items, such as glass aquariums & large cabinets, require special handling and must be sent out on a pallet, this is at a cost starting from £19.99 on some pallet deliveries depending on location. We don't offer free pallet delivery unfortunately (unless stated) due to the delicate nature of the glass aquariums and insurance required to transport.

We will contact any pallet delivery purchase before dispatch to arrange a suitable delivery date for you to receive the goods. We will not dispatch a aquarium pallet delivery until we have booked a delivery date with you the customer.

Note that the pallet delivery service is a drop at kerb only service, the drivers are not insured to handle goods into homes and you are required to dispose of the pallet.
