Can natural sea water be delivered?
No. It is collection only, from Marine Spec in Suffolk, and we do not post it. Message Harry on WhatsApp, or email info@marine-spec.co.uk, to arrange a time.
Questions first? Contact us, or read delivery and returns for the rest of the range.
What salinity and parameters should I expect?
Salinity is 34 to 36 ppt. The other common parameters are in the table. They are a guide, so test the water yourself before it goes in your tank.

Where does it come from?
The Jurassic Coast. It is sourced in 25 litre quantities for marine aquariums. The supplier states that natural seawater holds over 11 million forms of live beneficial bacteria per gallon, and is naturally enriched with calcium, iodine, magnesium, cobalt, potassium and zinc.
How do I collect it?
We run Marine Spec from home in Suffolk. Message Harry on WhatsApp, agree a time, and let us know before you set off.
Need water for top ups too?
We also sell 0 TDS RODI water for top ups and mixing salt, on the same collection only basis. Both sit in the water collection.
